ONima Bayan 1999 Conventional AC electric power systems are designed to operate with sinusoidal voltages and currents. However, nonlinear and electronically switched loads will distort steady state AC voltage and current waveforrns. Periodically distorted waveforms can be studied by examining the hamonic components of the waveforms. Power system harmonic analysis investigates the generation and propagation of these components throughout the system.

A short cause and effect survey on sources of harmonies and their effects on power distn bution systems is conducted.

As a basis for a power flow program different system components are modeled and the current spectnim of more common (harmonic producing) loads are not only simulated but also investigated through measurements.

In these studies after a brief review of the theoretical bais for hannonics power flow analysis, a software is developed applying Object-Oriented Analysis and Design Techniques and it has been utilized in the case studies.

Two cases are studied here fiom two different perspectives:

1. Case Study No. 1 (End User Perspective):

The Kautex-Textron case in harmonic analysis was conducted to identiG the problematic

harmonic orders in order to design appropriate power factor correction means in a

hannonicaHy rich indtistrial environment. 2. Case Study No. 2 (Power Utilities Perspective):

The Temporary Windsor Casino and the Casino Windsor case in which harmonics measurements were conducted to identim if there are any excessive harmonic injections into the local power utilities (Windsor Utilities Commission) network. ACKNOWLEDGMENTS

The main purpose of most of the active fields in power engineering is to supply the end- users (customers) with a reliable, high quality, continuous and economic source of electrical power.

In this chapter the definition of the power quaiity, its problems and the different categories of electromagnetic phenomena in power systems will be introduced in brief. The indices that are currently used for comparison and decision making are also introduced.

1.1 Power Quality Definition

The term "power quality" is a very inclusive term and encompasses a lot of phenomena in power systems. There is no global agreement on this term amongst the power system engineers.

One can Say that maintaining a certain sufficiently high grade of electric service provided cm be considered as the power quality. This is a philosophical answer but it does not include the definitiveness and precision of an answer.

But generally speaking: "Power quality wiil refer to the measure, analysis, and irnprovement of bus voltage (usually a load bus voltage), to maintain that voltage to be a sinusoid at rated voltage and frequency" [l 1.

There are five major reasons for the growing concern regarding the power quality issues:

Load equipment such as microprocessor based devices, and power electronics are more sensitive to power quality variations than products utilized previously for the same function. The increasing emphasis on overall high efficiency in power systems has introduced high efficiency devices (adjustable speed drives and shunt capacitor banks) and they in turn are major sources of increasing harmonies in the power systems.

Increased awareness of the end users.

As the power networks grow and get more interconnected, the failure of one cornponent has much more important consequences than before.

One of the most important reasons is the economical aspects of the power quality. A poor quality of power provided may cause the unwanted shut down of a system (factory, plant) which may be very expensive, on the other hand the customer billing rnay be affected by quaiity of the supply. For private utilities the quality of power supplied can be considered as a selling technique, especially with growing privatization in the power industry.

1.2 Power Quality Problems

Because of the nature of the power industry (being custorner-oriented and customer- driven) the following definition seems to be widely accepted amongst power system engineers: "Any power problem manifested in voltage, current, or frequency deviations that results in failure or misoperation of customer equipment is called a power quality problem" [2].

1.3 Classification of Power Quality Problems

The classification of power quality problems can be performed according to:

the source of the problem (e.g. converters, magnetic circuit nonlinearities,. ..)

wave-shape of problematic signal (e.g. harmonic , flicker, .. . )

frequency spectmm (e.g. radio frequency interference) Some examples of power quality problems are depicted in figure ( 1.1 ).

c = ringing froquency g - Cime d - irnpuise energy h - hipuise ampliludo

The following are a categorization of electromagnetic phenornena used for the power quality community.

Transients Impulsive Oscillating

Short Duration Variations Ins tan taneo us Momentary Temporary

Long Duration Variations Sustained Interruptions Undervol tages Overvoltages

Voltage Unbalance

Wave form Distortions DC offset Hannonics 1nterharmonics Notching Noise (wide band)

Voltage Fluctuations Flicker

Power Frequency Variations

ANS1 C84.1- 1982 and other standards more specifically depict duration and other characteristics of different categories listed above. These phenomena listed above can be described merby listing appropriate attributes. For steady-state phenomena, the foIIowing attri butes can be used:

Amplitude

Frequency

Spectrum

Modulation

Source impedance

Notch depth

Notch area

For non-steady-state phenomena, other attributes rnay be required:

Rate ofnse

Amplitude

Duration

Spectrum

Frequency

Rate of occurrence

Energy potential Source impedance

Reference [l] provides information regarding typical spectral content. duration, and magnitude where appropriate for each category of electromagnetic phenomena. The combination of these categories and their attributes provide a means to clearly describe an electromagnetic disturbance. They are also irnp~~ïtantin order to be able to classify measurcment resuits and to describe electromagnetic phenomena which can cause power qua1ity problems.

1.4 Power Quality Indices

Table (1.1) shows in bief the recommended indices in harmonic anaiysis of power systems and in conjunction with the interaction of power systern and other systems such as telephone, .. . . It is worth mentioning that some of these indices are not as critical and important as they used to be; for example, the Telephone Influence (Interference) Factor (TIF) is nowadays ignored due to digital and optical communication progresses. On the other hand, factors such as K-factor for transfomers are being more addressed both by the manufacturers and designers.

In table (1.1) the following notations are used: i as index is used for harmonic component of ith order h as index is used for harrnonic component of hth order

Wi weight of the ith harrnonic order ci weight of the ith harrnonic order

+/- as index positive or negative sequencc (respectively) In the following chapters some of these indices will be described in detail and used as scales and measures in our measurements.

* These indices cmbe decomposed in three phase cases to zero, positive and negative components. In some cases a breakdown of the even and odd harmonic components of these indices is useful.

Table 1.1 Common power quality indices Chapter 2 Harmonics in Power Systems

Conventional AC electric power systems are designed to operate with sinusoidd voltages and currents. However, nonlinear and electronically switched loads will distort steady state AC voltage and current wavefonns. Periodically distorted wave forms can be studied by exarnining the harmonic components of the waveforms. Power system harmonic analysis investigates the generation and propagation of these cornponents throughout the system.

Marrnonic studies have becorne an important component of power system analysis and design [24-261. They are used to quanti@ the distortion in voltage and current waveforms at various points in a power system and to determine whether dangerous resonant conditions exist and how they might be mitigated. Such studies are important because the presence of harmonic producing equiprnent is increasing. As harmonics propagate through the system they result in increased losses and possible equipment loss-of-Iife. Equipment cm be damaged by overcurrents or overvoltages resulting from resonances. Additionaliy, harmonics can interfere with control, communication, and protective equipment [27]. The ctment emphasis on power quality [28] has reinforced the need for harmonic studies as a standard component of power system analysis and design activities.

Interest in the analysis of harmonics and their effects dates back to the early 1900s. Subsequent harmonic modeling and analysis techniques were specialized to meet the requirements of High Voltage Direct Current (HVDC) systems and Static Var Compensators (SVC). Since the early seventies, the subject of power system harmonics has gained increasing attention due to the widespread use of static power converters 1291. Research in this area began to focus on the assessrnent of network-wide harmonic power flow. This led to the availability of fairly general techniques and software for the formulations and solutions of harmonic propagation problerns. An exarnple is the work of reference 1441. The work also spurred advances in the modeling of network components and in the collection of field experience. This chapter concentrates on the theoretical aspects of harmonies, section 2.1 provides a bnef review of some fundamental concepts.

2.1 Concept of Power System Harrnonics

Nonlinear and switched toads and sources can cause distortion of the normal sinusoidal current and voltage waveform in an AC power system. In this section, basic definitions and concepts associated with the analysis of periodic steady state wavefom distortion are discussed.

2.1.1 Fourier Scries and Harmonics

Under periodic steady sbte conditions, distorted voltage and current waveforms can be espressed in the fom of a Fourier Series. The Fourier series for a periodic fûnction f(t) with fundamental frequency o can be presented as:

The coefficients Cnand phase angles 0, for n-th harmonic are given by:

where T=2n/o and Co is the dc component of the function. The rms value of f(t) is defined as: (2-7)

In generaI, one can think of devices that produce distortion as exhibiting a nonlinear relationship between voltage and current. Such nonlinear relationships can lead to several forms of distortion as summarized below:

A periodic steady state exists and the distorted waveform cm be expressed as a Fourier series with a fundamental frequency equal to the power frequency.

A periodic steady state exists and the distorted wavefom cm be expressed as a Fourier series with a fundamental frequency that is a submultiple of power frequency.

The waveform is aperiodic but perhaps almost periodic. A trigonometric series expansion may still exist (as an exact representation or as an approximation) [45].

The first case is comrnonly encountered in harmonic studies. There are several advantages to decomposing waveforms in tems of harmonics. Hannonics have a physical interpretation and an intuitive appeal. As discussed later, the transmission network is usually modeled as a linear system. Thus the propagation of each harmonic can be studied independent of other harmonic components in the fiequency domain. Generally. the number of harmonics to be considered is smatl which simplifies the computations. Consequerices such as losses can be related to harmonic components and mesures of wavefom quality can be developed in tems of harmonic amplitudes. Certain types of pulsed or modulated loads and integral cycle controllers can create waveforms corresponding to the second category. The Fourier representation, when applicabk, cm be advantageous for the rasons cited above and measures if waveform quality can be adapted to such systems, although standards do not yet exist.

Some practical situations correspond to the third case. For example, dc arc fimaces consist of a conventionai rectifier input but the underlying process of melting is not a pex-iodic process. When reference is made to harmonics in this instance it corresponds to the periodic waveform that would be obtained if funiace conditions were to be maintained constant over a penod if time. Whiie such rnodeling obviously does not

predict the exact response, it cm, CO a certain extent, lend insight into some of the potential problems caused by the distortion producing devices.

2.2 Origin of Harmonics

There are two main sources of harmonics in conventional power systems:

1. Devices involving electronic switching: Static power converters are a typical example of such devices. The switching process is generally synchronized to 60 Hz and causes distortion on the switched waveforrns. The distortion can be studied by the Fourier Series method.

2. Devices with nonlinear voltage and current relationships: Iron core reactors are a typical example of such devices. When excited with a periodic voltage input, the nonlinear v-i relationship leads to the production of harmonic currents. Devices such as arc-fiirnaces also fa11 into this category.

2.3 Distortion Indices

The most commoniy used measure of deviation of a periodic waveform from a sinewave is called total harmonic distortion (THD) or distortion factor. THD = M,

Where Mh and Ml are the hth order and the fundamental harmonic orders respectively.

The terni distortion factor is more appropriate when the surnrnation in the equation above is triken over a selected number of hannonics. IEEE Std. 519 [24] specifies limits on voltage and current (THD) for "Low Voltage, General Distribution, General Subtransmission, and High Voltage systems and Dispersed Generation and Cogeneration".

Several other distortion indices are defined [24], each intended to capture a specific impact of harmonics. Telephone Influence Factor (TIF), the C-message weighted indices, and the VT and IT products are used to measure telephone interference. These indices have been revised by sorne utilities to reflect modem telephone cable design, changes in the coupling mechanism, and the response of modern receiving sets. The K-factor index is used to describe the impact of harmonics on losses and is usefbl in derating equipment such as transforrners [46]. Most harmonic analysis prograrns calculate and report these indices.

2.4 Power Definitions [47] Consider a two terminal device with voltage v(t) and current i(t), both of which are assumeci periodic and given by the Fourier series

The dc terrns have been omitted for convenience. The instantaneous power p(t) delivered to the device is then given by:

and contains oscillatory components at frequencies that are the surn and differences of the harmonic frequencies in v(t) and i(t). The real or active power represents the average power delivered to the device in the steady state and can be show to be:

In analogy with linear circuits with purely sinusoidal excitation it is comrnon to define the reactive power as:

The volt-amperes in the device can be defined as: Furthemore, we have an additional term, D, distortion volt-amperes, in the power triangle:

D accounts for the cross-fkequency tems inherent in S.

These definitions are used in power calculations and also in the formulation of some Iiarmonic analysis methods. Various alternative definitions and interpretations have been fonvarded and the reader is referred to 1481 for more detailed discussions.

2.5 Characteristics of Harmonics in Power Systems:

Most devices operate in an identical manner in the positive and negative half cycle, thus diminatins even order harmonics.

In balanced three-phase systems, under balanced operating conditions, harmonics in each phase have specific phase relationships. For exarnple. in the case of the third harmonic. phase b currcnts would lag those in phase a by 3x130" or 360°, and those in phase c would iead by the sarne arnount nius, the third harmonics are in phase and appear as zero-sequence components. As such, in a grounded wye system these hamonics flow in the Iines and neutraVground circuits, while in delta or ungrounded systems they cannot exist in Iine current at all. Similar analysis shows that fifüi harmonics appear to be of negative sequence, seventh are of positive sequence, etc. Therefore, the impedances and manner of connection of rotating machines, transmission lines, and transfomers must be modeled carefully for each harmonic. The harmonics produced by many devices, pariicularly solid-state power converters are well-defined 'characteristic harmonics'. An ideal, p-pulse, line-cornrnutated, converter, for exarnple, produces AC side harmonic currents of order npf: 1, n= I,2,3 .... 2.6 Sequence of Different Harmonics

Table (2.1) simply shows the tabulation of sequences for different harmonic orders. As can be seen triplen harmonics (odd multiples of the third harmonic) are of zero sequence and therefore are additive and may cause over load of the transformer neutrals in grounded wye side of the distribution transfonners.

Table 2.1 Sequences of differcnt harmonic orders

The proliferation of the triplen harmonics generated by nonlinear, single-phase loads cause special concerns for multi-grounded wye distribution systems. The triplen portion of the harmonic current will add in the neutral for loads connected phase to neutral. This is widely recognized in building wiring systems where neutral ampacity is of concem. Unfortunately, there are two more concerns particular to multi-grounded wye systems. Further, these concerns are not generally recognized.

The triplen harmonic neutral current increases the risk for stray voltage complaints especially near substations. The harrnonic neutral current also increases EMF levels near three phase distribution feeders.

Electronic loads (cornputers, televisions, stereos, compact fluorescent light bulbs, adjustable speed drive heat pumps, and electric vehicle battery chargers etc.) exhibit nonlinear characteristics. individually, these loads are too small to cause any noticeable current distortion on a distribution system. If these loads increase coIlectively, however, harmonic current levels will gradually increase and may become a signifiant problem for utiIities[49]. The interpretations discussed above do not apply to the unbalanced cases. when supplied with unbalanced voltage, most three-phase power electronic converters can generate non- characteristic harrnonics. In many cases, the three-phase hannonics do not follow the sequence order of the balanced cases. Furthemore, the nature of some harmonic problems requires the assessrnent of unbalanced harmonics. For example. zero sequence harrnonic currents generally cause much more interference with telephone circuits han positive or negative sequence harmonics. Systems with unbalanced loads and components need to be studied using a the-phase mode1 with proper representation of neutral and ground circuits.

2.7 Effect of Harmonies on Power Systems

Once the harmonic sources and their magnitudes are defined, they must be interpreted in terrns of their effect on system and equipment operation. Individual elements of power system must be exarnined for their sensitivity to harmonics on the basis of recommendations and standards such as IEEE 1 8 (shunt power capacitors)

The main effects of voltage and current harrnonics within the power system are :

Amplification of harrnonic levels resulting from series and parallel resonance

Reduction of efficiency in power generation, transmission and utilization due to

Increase in losses (Iron and copper losses)

Harmonic torque in induction motors

Aging of the insulation of electrical components and reducing their useful life

Mal-operation of devices such as:

Frequency or wave-shape sensitive devices (Adjustable Speed Drives, .. .)

Relays and protection devices (impedance due to the third harmonic) Metering devices

Interference with control devices (PF control, electronic circuits.)

Triplen harrnonic currents create special problems for multi-grounded wye distribution systems with loads comected line to neutral. Triplen harmonics, especially the third, add in the neutral with very little cancellation. The increased neutral current raises neutral to earth voltage (NEV) to levels that cm increase electric shock stray voltage complaints. Magnetic fields near these lines will be higher when tnpien hannonics are present. These two particular concems are new issues that have not been previously addressed. It is dificult to estirnate the full impact of this phenornena. Further, solutions will be needed. Five wire systems seem expensive. Strict harmonic limits are unpopular with equipment manufacturers. Local supply of harrnonic current may be needed [49].

Interference with communication systems

2.8 Harmonics Analysis Methods

Techniques used for analysis of harmonics are discussed in more detail in chapter 3. Here we want to bnefly mention other non-main-stream techniques that have been used on case by case basis.

2.8.1 Identification of Harmonic Sources Using Kalman Filter

Due to cost, the number of harmonic rneters in power systems is very limited as compared to fundamental fiequency measurements. The requirement for redundant harrnonic measurements in harmonic state estimation can not be met in most power systems. The limitation in the number of harmonic meters makes the harmonic statc estimation an underdetermined estimation problem [Il]. The quality of estimations is a function of the number and locations of the harmonic measurements. So, for a given few harrnonic meters, one of the problems needed to be solved in the harmonic state estimation is how to arrange the Iimited hamionic meters in power systems to obtain optimal harmonic state estimation. Furthemore, in a power distribution system, nonlinear load devices may be three-phase unbalanced to some extent and they may even exist in just one phase or two phases of the system. As a result, the unbatance of harmonic sources further complicates the harmonic sources identification problems.

Electric utility companies are becoming more concerned about power system harmonics and voltage distortion in recent years. Usually, the nonlinear loads or harmonic sources occur possibly everywhere in power systems and they operate at a continuously variable power levei. The locations and magnitudes of harmonic source injections depend on placements of nonlinear Ioad devices in the systems and their ratings. For these reasons, it is beneficial to estimate the locations and time-varying magnitudes of harmonic injections, eliminate them and provide high-quality electricity. Girgis and Ma show a method of identification of these harmonics using Kalman filters [l Il.

2.8.2 Wavelet Transform Analysis

This approach is based on wavelet transform analysis, particularly the dyadic- orthonormal wavelet transform. The key idea underlying the approach is to decompose a given disturbance signal into other signals which represent a smoothed version and a detailed version of the original signal. The decomposition is performed using multi- resolution signal de- composition techniques. It is shown [15] that this technique is suitable for detection and localizing disturbances with actual power line disturbances. In order to enhance the detection outcomes, the squared wavelet transform coefficients of the analyzed power line signal are utilized. The investigation is based on characterizing the uniqueness of the squared wavelet transform coefficients for each power quality disturbance [15]. 2.8.3 Statistical Approaches to Harmonie Analysis

Simulation is presentiy the most curent tool to analyze harmonic propagation conditions in large systems. Indeed, the large size of transmission networks (similar to the wavelengths of the harmonics which propagate) can be at the root of resonance phenomena and their meshed structure, multiplies the equations needed for their description. The two specific factors prevent the use of any other deterministic calculation method insofar as they entangle cumbersome and rapidly excessive mathematical expansion. However, the condition for proper operation of a simulator is an accurate description of al1 system components (lines, loads, transformers, generators, ...). Consequently "boundary-equivalent load models" must be used. They have to be computed as a function of active and reactive power transfers at the bdarnental frequency [16]. For case by case studies, a simplified approach of the phenomena appears to be a useful alternative to the lengthy irnplernentation of traditional simulation process.

The principle of this method is the transformation of a portion of the meshed transmission network into a standard ladder circuit which is easier to analyze. Insofar as it preserves the electrical properties of the selected nodes (harmonic voltages, currents and impedances), this transformation dlows al1 the magnitudes relating to harmonic propagation to be calculated without the difficulties of writing and solving complex equations linked to the system meshing. Equivalent impedances are introduced, characterizing the attenuation induced by the network.

2.9 Harmonics Damage Prevention

Different methods are suggested to prevent fiom propagation of harmonics in the power systems and fiom the sources to the other locations and customers. Several methods are suggested to evaluate the economical damage due to harmonic losses[l8, 191.

Filtering the harmonics to the ground, separation of customer and supply side harmonic contributions [17], a combination of fitters and power factor correction capacitor banks and prevents ffom unnecessary penalties, but also filters out the most significant harmonic order which is discussed in detail in chapter 7.

In this chapter we present a review of the modeling and analysis of harmonic propagation in electric power systems, two cases are studied in chapter 7. We concentrate on the theoretical aspects of harmonics modeling and simulation. Concepts and characteristics of power system harmonics. modeling of harmonic sources and network components, and techniques for network-wide harmonic analysis are discussed.

Section 3.4 presents peneral goals, formulation and solution of the harmonic propagation problem. The modeting of harmonic sources and network components are discussed in sections 3.5 and 3.6, respectively.

3.1 Power Flow (Problem Definition)

The voltage current relation of an N bus power system can be presented in nodal form of:

The computer can determine the elements of the N by N bus admittance matrix of which the typical element Y, is

Other essential information includes transformer ratings and impedances, shunt capacitor ratings, and transformer tap settings. In advance of each power-flow study certain bus voltages power injections must be given known values, as discussed below.

The voltage at a typical bus i of the system is given in polar form by and the voltage at another bus j is similarly written by changing the subscript fiom i to j. The net current injected into the network at bus i in terms of the elements Y,,of Y, is given by the summation

Let Pi and Qi denote the net real and reactive power entering the network at the bus i. Then, the complex conjugate of the power injected at bus i is

in which we substitue from the definitions of Y, and V, above

Expanding this equation and equating real and imaginary parts, wre obtain

Equations (3.1) and (3.2) constitute the polar form of the power-flow equations; they provide calculated values for the net real power Pi and reactive power Qientering the network at typical bus i . Let Pi denote the scheduled power demand of the load at that bus. Then. Pi,, = Pgi - Pdi is the net scheduled power being injected into the network at bus i. Denoting the calculated value of Pi by Pi,a,, leads to the definition of mismatch APi as the scheduled value Pi,, minus the calculated value Pi,,,, . Li kewise, for reactive power at bus i we have

Mismatches occur in the course of solving a power-flow problem when calculated values of Pi and Q, do not coincide with the scheduled values. If the calculated values P,,, and QI.,,, match the scheduled values Pish and QI,, perfectly, then we Say that the mismatches APi and AQi are zero at bus i, and we wite the power balance equations

As we shall see these two functions are cost fùnctions (targets) to be minimized in the course of a power-flow problem.

In general in power systems 3 types of buses are identified. At each bus 2 of the four quantities are specified and the other 2 are calculated

This section reviews the techniques presently being used for power system harmonic analysis. These techniques vary in terrns of data requirements, modeling complexity, problem formulation and solution algorithms. New methods are being developed and published.

Frequency scan is the simplest and most cornmonly used technique for harmonic anaiysis [l O]. The input data requirements are minimized. It calculates the frequency response of a network seen at a particular bus or node. Typically, a 1 per unit sinusoid current (or voltage) is injected into the bus of interest and the voltage (or current) response is calculated. This calculation repeated using discrete frequency steps throughout the range of interest. Mathematically, the process is to solve the following network equation at frequency n.f,:

where [I .]is the known current vector (for current injection scan) and [V ,,] is the nodal voltage vector to be solved. In a typical frequency scan analysis, only one entry of [I ,] is nonzero. In other analysis, a set of positive or zero sequence currents may be injected into three phases of a bus respectively. The results are the positive or zero sequence driving- point impedance of the network. Frequency scan analysis is the most effective tool to detect harmonic resonance conditions in a systern. It has also been widely used for filter design.

If more data are available on the harmonic source characteristics, the frequency scan analysis cm be expanded to determine additional harmonic distortion information. For example, the 1 per unit injection current can be replaced by a specific harmonic current. The current has a magnitude determined from the typical harmonic spectnim and rated load current of the harmonie-producing equipment under study: where n is the harmonic order and the subscript 'spectnun' indicates the typicai harmonic spectrum of the element, Typical spectnims of some harmonic sources can be found in a number references such as reference [24]. The system of equations is then solved only at harrnonic frequencies. The results are the hannonic voltages created by the hamionic- producing equipment. To compute the distortion indices such as THD, the nominai bus voltage at fundamental fiequency is used. ïhis approach has been extended to cases with multiple harmonic sources in sorne harmonic analysis programs. The extension, however, is approximate if the phase angles of the injection currents are set arbitrarily. Depending on the phase angles used, the effects of two harmonic sources seen at a particular bus can either add or cancel. The results can be either pessimistic or optimistic.

A fundamental frequency load flow solution is needed to extend the above approach to accurately mode1 multiple harmonic sources. Typical phase relationships between the fundamental fiequency current and the harmonic currents of the nonlinear element must be available as welL The load flow, modeling the hannonic-producing devices as constant power Ioads, calculates the fùndamental frequency current injected from the load to the system. Assuming that the current has a phase angle of O,, the phase angle of hannonic current 8, corresponding to that nonlinear element can be determined by:

where 0,-,,,, is the typical phase angle of the harmonic source current spectnim. This approach is very effective for analyzing power systems with power electronic devices. The fundamental fiequency load flow solution is also beneficial for providing more accurate information such as base voltages that can be used for distortion index calculations. The magnitudes of harmonic current sources tend to be more accurate as well since the load flow dependent base current, not the rated current, is used to determine the harmonic current magnitudes. Data requirements for this type of analysis can normdly be met.

The main disadvantage of these methods is the use of typical hannonic spectra to represent harmonie-producing devices. This prevents an adequate assessrnent of cases involving non-typical operating conditions. Such conditions include, for example, partial loading of harmonie-producing devices, excessive harmonic voltage distortions and unbaianced network conditions. Even under ty pical conditions, the voltage-dependent harmonic-producing nature of nonlinear devices may make the accuracy of typical spectrum based methods unacceptable. For some devices with nonlinear v-i reiationships, the voltage-dependency is so strong that no typical spectra exist. These considerations prornoted the development of a nurnber of advanced harrnonic analysis methods.

One of the well-known methods is the so-called 'harmonic iteration' method [50-52!. In this method, a harmonic-producing device is modeled as a supply voltage-de.~endent current source:

where (V, ... VJ are the harmonic phasors of the supply voltage, and c is a set of control variables such as converter firing angle or output power. This equation is first solved using an estimated supply voltage. The results are used as the current sources in voltage based system of equations from which bus harmonic voltages are then solved (for the fundamental fiequency, load flow equations can be used). The voltages are in tum used to calculate more accurate harmonic current sources fiom The above mentioned equation. This iterative process is repeated until convergence is achieved. One of the main advantages of this 'decoupled' approach is that the device mode1 cm be in a closed fom, a time-domain simulation process, or any other form. Reliable convergence has been reported in many case studies. although difficulties occur near sharply tuned resonances. Convergence can be improved by including the equivalent admittance of nonfinear devices into the admittance matrix [5 il.

Another method that takes into account the voltage-dependent nature of nonlinear devices is to solve system of equation and device equation simultaneously using Newton type algorithms [44, 53, 541. This method generally requires that the device models be available in a closed form or in a form wherein derivatives can be efficiently computed. In tiieory. convergence of this method is better than that of the harmonic iteration scheme if the iteration starting point is close to the solution point. A variation of this method is the formulation of the systern equation. In reference [44], system equation is formulated as a power flow equation and the control variables (firing angles) are solved based on the converter power specifications.

The various methods above have been extended to the case of unbalanced three-phase systems by recasting the system equation and the device equations in the rnulti-phase domain [51,55,56]. A multiphase (or three-phase) approach to harmonic analysis has some advantages. First is the modeling of zero-sequence harmonic flows. Even under balanced conditions, some harmonie-producing equipment such as three-phase transformers can generate zero sequence harmonics. Second is the capability of assessing the generation of non-characteristic harmonics. These harmonics, generated under unbalanced conditions, can be harmfùl since mitigation measures are normally not designed for them. Furthemore, three-phase modeling can easily represent the phase- shifiing effects of transformers on harmonics.

Besides the frequency-domain methods described above, techniques have also been deveIoped for harmonic analysis in the time domain [57]. The simplest approach is to run a time simulation until a steady state is reached. Electromagnetic transient prograrns such as EMTP have been used as such a tool. Complex techniques, such as the shooting rnethod [58] have been proposed to accelerate the convergence to steady state. One of the main disadvantages of time-domain based methods is the lack of load flow constraints (such as constant power specification at load buses) at the fundamental fiequency. In summary, the problem of harmonic analysis can be cast mathematically as the solution of a network equation and a set of device equations at fiindamental and harmonic frequencies. The network equation can be forrnulated in an admittance matrix form or in a power flow equation form. The device equations can be as simple as known current sources or as complex as control-variable dependent circuits. Which technique to use for a particular hannonic problem is, to a large extent, determined by the available data. An important consideration in harmonic analysis is to use a method cornmensurate with input data accuracy.

It is appropriate to note that a large nurnber of harmonies related problems encountered in practice need to be analyzed by a combination of the various methods. Measurements may also be an essential component in the analysis. For example, a fiequency scan is ofien used to determine the resonance fiequencies and desirable filter responses, while harmonic power flow solutions are applied to detennine distortion levels and to check cornpliance witfi hannonic limits. For cases with only one hannonic source. inclusion of phase angle information is not cntical. On the other hand, for the studies of HVDC/SVC systems or saturation of large power transformers with direct current offset, three-phase harmonic power flow analysis may be used.

3.5 Nature and Modeling of Harmonic Sources

3.5.1 Nonlinear Voltage-Current Sources

The most cornrnon sources in this category are transfonners (due to their nonlinear rnagnetization charactenstics), fluorescent and other gas discharge lighting, and devices such as arc-furnaces. In al1 cases there exists a nonlinear reiationship between the voltage and current. For devices such as core-and-coi1 ballasted fluorescent lights, the relationship can be relatively constant over a reasonabte range of excitation. In the case of transformers, on the other hand, it can be very complex if hysteresis characteristics of the magnetic materials are considered. In the case of arc-fumaces the voltage-current relationship has both a time-dependent variation depending on the stage of rnelt as well as a random variation.

The harmonic currents generated by these devices are more aifected by the waveforms and peak values of supply voitages than electronic switching devices. It is desirable to represent the devices with their actual nonlinear v-i characteristics in harmonic studies, instead of as voltage independent hamonic current sources. Both harmonic iteration and Newton methods have been proposed to more accurately mode1 these devices [593.

3.5.2. Line-Commutated Solid State Converters

By line-commutated solid-state converters we mean electronic power converters supplied from the ac system in which the switching of devices is synchronized to zero-crossings of the ac voltage or its fundamental component. Generally a periodic steady state exists. Under ideai conditions devices switch in an identical manner in the positive and negative halfcycles and thus only odd-harmonic components exist. Compared to the nonlinear v-i devices, harmonic currents generated fiom converters are less sensitive to supply voltage distortion. Harmonic current source models are therefore commonly used to represent these devices. As discussed before, the phase angles of the current sources are functions of the supply voltage phase angle. They must be modeled adequately for harmonic analysis involving more than one source. Typical devices utilizing line-commutated solid state converters include static var compensator, HVDC link and dc dives.

Static Var Compensators (SVC):

These devices normaily have large MVar ratings and are connected to high voltage transmission systems. Harmonic currents generated from SVCs may therefore affect a large nurnber of customers and equipment [60].Common SVC-related harmonic studies tend to represent the device in detail. Factors such as firingangle dependent harmonic çeneration and supply voltage unbalance are taken into account. These studies normally scan through various possibte SVC operating conditions and filter performance under each condition is evaluated.

Three-Phase Static Power Converters:

The most common form of static power converters is the six-pulse bt-idge rectifier type. It is widely used as the front end for HVDC terminals, dc drives and adjustable speed drives. The nature of the bridge cormection precludes the generation of zero sequence harmonics from the converter, even when the supply voltage is unbalanced or distorted. Several six-pulse converters may be comected in a multipulse form which allows el imination of several harmonics. The harmonic current spectmm is moderatel y sensitive to the converter firing angle.

Although equipped with a similar bridge converter front-end, harmonic currents generated by HVDC terminals, dc drives and adjustable speed drives differ significantly. This is due to the different dc link designs. ln the case of HVDC [6 11, sufficient dc link filters are available to filter out the dc link current ripples. Therefore, the waveforms of HVDC ac side current are very close to the well-known rectangular shape. In the case of dc drives, however, dc link filters are normally not present and the dc motor inductance is used for current smoothing [62]. Thus the dc drive current contains higher harmonic components. Most adjustable speed drives (the voltage-source inverter and puls-width modulated types in particular) have a large capacitor in the dc link [63]. This capacitor amplifies the dc link (converter side) current ripple. As a result, the ac side current has higher harrnonic levels (See Figure 3.1 ). Figure 3.1: Typical ccrrent waveforms of 6-pulse HVDC links, dc drives and adjustable speed drives.

Sinde-Phase Staiic Power Converters:

These converters are commonly found in electronic equipment (computers and Ws), small adjustable speed drives and others. The most common single phase power supply consists of a capacitively filtered rectifier followed by different types of regulating stages. Such a supply draws pulses of current corresponding to periods of time in each half-cycle where the line voltage exceeds the capacitor voltage. The spectnim consists of al1 odd harmonics with magnitudes depending on the shape of the pulse 1241.

Theoretically speaking, these devices can be represented Individually in network-wide harmonic studies as harmonic current sources. The problem is that there exist a number of such devices in a typical system and detailed studies using harmonic power flow programs becomes impracticai. What really is of concem in distribution system harmonic analysis is the collective effects of such devices [64].

3.5.3 High Frequency Sources

Advances in power electronic devices have created the potential for a wide range of new power conversion techniques. nie electronic ballast for Fluorescent lighting is included in this category [65]. Other possibilities include techniques for improving current waveshape and power factor, minimizing filter requirements, and minimizing switching losses. In gened. these systems employ high fiequency switching to achieve greater flexibility in the power conversion. With proper design, these techniques can be used to reduce the low frequency harmonies. Distortion is created at the switching fiequency which is generally above 20 kHz. Due to its high fiequency, the distortion generally cmotpenetrate far into the system.

3.5.4 Non-Harmonic Sources

There exist several power electronic systems which produce distortion at fiequencies that are not integer multiples of the fundamental frequency. There are dso devices whose (aperiodic) waveforms do not have a Fourier series representation. Lachg standard terminology, we will cal1 these non-harmonic sources. These sources are discussed here for completeness.

Cvcloconveners

Cycloconverters use static switches to convert a constant frequency fixed voltage source of ac power to a variable, lower frequency, controlled voltage output. Typical current drawn by the devices consists of a few periodic components whose fiequencies are lower than the source frequency. Reference [66] describes a three-phase 60 Hz to single-phase 25 Hz cycloconverter for a traction system. The distortion fiequencies for this converter include:

where f, is the input frequency, f, is the output frequency, and f, is the distortion frequency. This converter, having a fixed output fiequency, produces distortion at fixed frequencies. Doublv Fed Machine Drives

Doubly fed machines are a class of wound rotor induction machines in which, typically, the stator is fed from the utility supply, while the rotor is fed by a variable voltage, lower power, variable fiequency electronic source. In these machines, the rotor currents will be of the slip frequency. With electronic converters supplying the rotor windings, the winding currents will carry harmonics of the slip frequency. These will be coupied through the air gap to the stator, causing currents in the stator winding at fiequencies which are not harmonics of the stator fiequency. This application is more diffficult to study due to the fact that the fiequency of these currents resulting fkom slip fiequency harrnonics will Vary with the rotor speed. Therefore a system resonance at any fiequency will be excited for some particular operating speed [67].

Adius f able S~eedDrives

Adjustable speed drives may also inject non-harmonic currents back into the power system. The magnitude of these currents will depend on the design of the ASD. Reference

[68] reports harmonic currents of low magnitude at the fiequencies f = 6f; 4 f,, where is the inverter fiequency and f, is the AC system frequency. This reference cites a case study where an ASD excited a resonance at a non-harmonic fiequency.

3.6 Models for Network Components

This section summarizes the typical representations of comrnon network components for harmonic analysis.

3.6.1 Overhead Lines

The modeling of transmission lines and transfomers over a wide range of fiequencies is relatively well docurnented in the literature [29]. Typical overhead lines can be modeled by a multiphase coupled equivalent-pi circuit as shown in Figure 3.2. For balanced harmonic analysis, the mode1 can be fiuther simplified into a single-phase pi-circuit determined fiom the positive sequence impedance data of the line. The main concems for modeling overhead iines are:

O The frequency-dependency of the unit-length series impedance. Major causes of the frequency-dependency are the earth retum effect and the conductor skin effect.

The distributed-parameter nature (long-line effects) of the unit-length series impedance and shunt capacitance.

Figure 3.2: Overhead line model.

To construct a line model as shown in Figure 3.2, the unit-length series impedance and shunt admittance parameters are first computed according to the physical arrangement of the line conductors. The series impedance is composed of external and interna1 impedance. The external impedance is a function of earth return condition and the frequency of interest. This impedance is determined fiom Carson's formula 1691. The conductor skin effect is important in the calculation of the interna1 resistance because its increase with fiequency can be considerable. Sophisticated skin effects equations [70]are based on Bessel fimctions and a separate formula [69] rnust be used for stranded (compared to tubular) conductors for improved accuracy at higher frequencies. Approximate expressions are applied in several programs [70,711: where p, is the relative permeability of the cyiindrical wire, f is the fiequency in Hz and Rd, is the dc resistance in n/km.

After obtaining the unit-length parameters. matrices [Z] and [YI can be calculated by including or not including the long-line effects. If long-line effects are ignored, which is only applicable to short lines or low order harmonics cases, the [Z] and [Y] matrices are the unit-length parameters multiplied by the line length. If long-line effects are to be included, the [Z] and [Yj, the matrices should be cornputed using the well-known hyperbolic Iong-line equations [72]. For multiphase lines, the equations are in matrix form and are solved using nodal transformation [72,73].

Some guidelines cm be given as to the use of the line models discussed. Inclusion of the frequency-dependent effects requires the calculation of unit-length line constants for each harmonic fiequency. This requires much input data for harmonic analysis prograrns. The earth return effects mainly affect the zero-sequence harmonic cornponents. The conductor skin effects mainly affect the line resistance which in turn affects the damping level at resonance frequencies. Therefore, if zero sequence harmonic penetration and damping at resonance frequencies are not of significant concern, the fiequency-dependency effects may be neglected. In this case, a single unit-length [Z] matrix computed at the dominant resonance frequency is adequate.

Whether or not to include the long-line effects depends on the length of the line being modeled and the harrnonics of interest. An estimate of critical line lengths where the long-line effects should be represented is 150h miles. where n is the harmonic number. Finally. reference [73] suggests that for line lengths of 250 km for the third harmonic and 150 h for the fifth, transpositions are ineffective and can aggravate unbalance. Thus three-phase line mode1 should be considered. 3.6.2 Underground Cables

Underground cable models are very similar to overhead line models. The long-line effects of underground cables cm be represented in the same way as that used for overhead iines. The difficulty for cable modeling is the determination of unit-length parameters for a cabIe. Reference [72] provides detailed descriptions on the calculation of cable parameters. Cables have more shunt capacitance than overhead lines. Therefore. long-line effects are more significant. An estimate of critical cable lengths where the long-line effects should be represented is 90/n miles.

3.6.3 Transformcrs

Figure 3.3 shows one relatively general mode1 for a multi-winding transformer that is adequate for harmonic analysis. The resistance R, is a constant resistance that accounts for cors loss. R, and Li represent the winding resistance and leakage inductance, respectively. of winding i. Resistance qi is used to represent the fiequency dependent characteristics of short-circuit resistance and inductance.

Figure 3.3: Transformer Model.

The characteristics of a transformer that affect hannonic flows are the short circuit impedance, magnetizing characteristics and winding connections. Although the resistance and inductance components of the transformer short circuit impedance are fiequency dependent, modeling them as constant R and L is generally acceptable for typical liarmonic studies. This is because the fkquency dependent effects are not significant for the harmonic fiequencies of comrnon interest. The current source in Figure 3.3 is used to represent the harmonie-generating effects of the magnetizing branch. The value of the current source should be determined fiom the flw-current curve and the supply voltage. Indusion of the saturation characteristics are important oniy when the harmonics generated by the transformer are of primary concem. Exact replication of saturation is virtuaily impossible due to the complexities of local phenomena in the magnetic core and minor Ioop hysteresis. If a transformer is subject to a dc current injection, hannonics generated from the magnetizing branch cmbe signi ficant

Transfomers can give a +30 degree phase shifi to harmonic voltages and currents, depending on the harmonic order, the sequence, and transformer connections. Modeling phase shifiing effects is essentid if there is more than one harmonic source in the system. Three-phase representations automaticdly include phase-shifting effects. Single-phase approaches should use a phase-shifter mode1 to represent the effects.

Other factors such as the nonlinear resistance characteristics of the magnetizing branch and winding stray capacitance may also affect the harmo~cperformance of a transformer. For most trans fonners, however, the e ffects of stray capacitance become noticeable only for fiequencies higher than 4 kHz. Harmonies due to nonlinear resistance is small compared to the nonlinear inductance. Therefore, these effects may need to be considered only for extreme conditions or specially-designed transformers.

3.6.4 Rotating Machines

In synchronous and induction machines the rotating magnetic field created by stator harmonics rotates at a speed significantly higher than that of the rotor. Therefore at harmonic frequencies the impedance approaches the negative sequence impedance. In the case of synchronous machines the inductance is usually taken to be either the negative sequence impedance or the average of direct and quadrature subtransient impedances. For induction machines the inductance is taken to be the locked rotor inductance. In each case the frequency-dependency of the resistance can be significant due to skin effects and eddy current losses. The resistance normally increases with fiequency in the form of ha, where h is the harmonic order and a is in the range of 0.5 to 1 S. Figure 3.4 shows the negative sequence impedance of a 1100 hp synchronous motor as a hction of fiequency. Most rnotors are connected in delta or ungrounded star form. These motors do not provide a path for zero sequence harmonic currents.

Figure 3.4: Measured impedance of a synchronous motor.

For salient pole synchronous machines, a negative sequence fundamenta! fiequency current in the stator winding induces a second harmonic current in the field winding. The hamonic current can in huri induce a third harmonic current in the stator. A similar situation arises for the unbalanced harmonic currents in the stator winding. This harmonic conversion mechanism causes a salient pole synchronous machine to generate harmonic currents. A more accurate machine mode1 has been proposed to take such effects into account [543.

3.6.5 Passive Loads

Linear passive loads that do not produce harmonies have a significant effect on system frequency response primarily near resonant frequencies. As in other power system studies it is only practical to model an aggregate load for which reasonably good estimates (MW and MVAR) are usually readily available. Such an aggregate must include the distribution or service transformer. At fundamentd frequency the effect of distribution transformer impedance is not of concern in the analysis of the high voltage network. At harrnonic fiequencies the impedance of the transformer can be comparable to that of motor Ioads, since induction rnotors appear as locked-rotor impedances.

A general model for passive loads is given in Figure 3.5. To properly characterize this model it is necessary to know the typical composition of the load. Such data are usually not easily available. The followi~gmodels have been suggested in literature [IO] (n represents the harmonic order):

Model B: Paraiicl RL with R =v/(k.f); L=Vf/(k2nfOQ), k= O.ln+0.9.

Mode1 C: ParalEEI R,L in series with transformer inductance L, where R=V2/P: L=nR/(6.7*2%fe(Q/P)-0.74); L,=O.o73nRR*.

Mode1 A assumes that the total reactive load is assigned to an inductor t. Since a majority of reactive power cornes fiom induction motors, this model is not recomrnended. Model C is derived fkom measwements on medium voltage loads using audio frequency ripple generators. The coefficients cited above correspond to one set of studies [28], and rnay not be appropriate for al1 loads.

Figure 3.5: Basic Load Model. Chapter 4 Spectrum Analysis Through Simulation

A successfUl hmonic power flow anaiysis on a network depends on the appropriate modeling of network components. In chapter 3 modeling of distribution network components were introduced and descnbed. One of the most important components are the loads which introduce current distortions into the system and the passage of these distorted currents through the distribution network impedances imposes voltage wave forrn harrnonics on the power system.

In this chapter the loads and their modeling are being analyzed as a bais for every hamonic analysis. Here we first focus on simulation of typical industrial or harmonically rich single phase loads, and in chapter 5 with the aid of measurement we back up the results of our simulation and extend them to the real industrial and combined loads measurements.

4.1 Simulation of Loads

The voltage - current characteristics of diEerent loads in conjunction with the application of a sinusoidal voltage wave form have been used to find the resultant current wave form of different load types, varying from an ordinary fluorescent lamp to a highly excited transformer. Application of point by point method to the aforementioned wave forms resuIts in the current wave forms which is then analyzed in order to find the current harmonic spectrums.

MATLAB 5.0 has been used for the purposes of point findinç and analysis. Voltage - current characteristics have been gathered form a variety of different sources 13 0-431.

The results of these anaiysis are added to the library of non-linear loads, which is used for modeling of general loads in different cases. As a consequence application of current injection method would be facilitated. 4.2 Fluorescent Lamp

The principle of operation of a fluorescent light is based on conduction in a gaseous medium. This phenornena is intrinsically an arc which involves the passing of electrons through the gas 1381 and has a non-linear v-i characteristic as shown in figures 4.1 and 4.2.

City Street liçhting is another area where assessinç the impact of the harmonic distortion phenornenon is becoming a very important issue to distribution utiiities. In fact, over the last years significant technoloçical advances and a massive use of a wide variety of efficient lamps have started to occur.

Gas discharge and fluorescent lamps polynomial models have been developed in the past [32], 1331, and included in harmonic analysis algorithrns [34]. These models use experimental measurements to determine the polynomial coefficients. The experimental data reported in previous works, and used to build these models [34] have been based on Iaboratory measurements of a very small sample of gas discharge and fluorescent lamps (not collected from the distribution network).

Reference [30] presents new experimental measurements, perforrned on a representative number (approximately 360) real-life gas discharge Iamps including different lamp and ballast manufacturers and having several years of operat ion (in average).

The results obtained contribute to a better understanding of the harmonic distortion caused by gas discharge lamps. Also, they allow to add these lamps to the list of other non-iinear loads, for the purpose of harmonic analysis in distribution networks. 0) FLC Lqht Currem

The same principles goveming the operation of a fluorescent light are applied to the arc fumaces as they involve the same phenornena. The only difference will be in the operating dernands which may cause the arc fùmace to work in more adverse conditions causing more distortion in current wave fonn [35].

4.4 Semiconductor Based Circuits

As a consequence of the advances in power electronics technologies over the last two decades, power electronics applications have quickly spread to al1 voltage Ievels, €rom EHV transmission to Iow voltage circuits in end user facilities [39].

ComrnonIy observed power electronics applications include HVDC terminais, various static VAR compensation (SVC) systems, hiçh power AC to DC converter for DC arc fùrnaces, static phase shifter, isolation switch, load transfer switch, converter-inverter based drive technologies, active line conditioning, energy storage and instantaneous backup power systems, renewable energy integration, and numerous others covered under subjects of Flexible AC Transmission Systems (FACTS) and Custom Power Systems (CPS). The need for power electronics modeling and simulation is driven by both existing and new applications.

Power electronics modeling can be divided into two basic categories, depending on study objectives.. The first category covers al1 steady state evaluations. The focus is on the power system response to the harmonies injected from a power electronics sub-system.

50 Examples of this type include a study of the steady-state harmonic propagation in a transmission and distribution system, harmonic fiequency resonance, system voltage and current distortion, filtering design calculation and performance evaluation, telephone interference analysis and system losses associated with harmonics. In this type of study, the harmonie-current injection can often be assumed independent of the voltage variations at a point of common coupling (PCC), an electncally dividing point between the utility system and the customer circuit. Therefore, the power electronics subsystem can be ereatly reduced to a shunt circuit equivalent. C

The second type of power electronics modeling covers a much more extensive and cornplex range of practical problems. In rnany applications, operation of a power electronics sub-system depends closely upon the operation state of the connected system. To evaluate the dynamic and transient performance of a system with power electronics interfaces, the monitoring and control loops of the system, includinç detailed signal processing and power electronics device firing need to be modeled. Examples of this type of applications can be an SVC system, a superconducting Magnetic Energy Storage (SMES), active power conditioning system and various adjustable speed drives applications. When rnodeling these applications, variations of systern parameters need to be used to derive the power electronic controls so that the output of the power electronics sub-systern changes accordingly as demanded. Because in these cases, the power electronics sub-system directly affects overall system operation, a separate treatment of the supply system and the power electronics sub-system is unacceptable.

Here Our focus will be on the first type or steady state modeling of the semiconductors modelinç with an emphasis on fiequency domain simulation. (For time domain based simulation rnethods and dynamic simulation of these circuits IEEE Task Forces publications are recommended [41-431). Here techniques suggested in [39]are used to simulate typical 6-pulse and 12-pulse 3-phase thyristor converter circuits. The results perfectly match the analytical method followed in [IO].

4.5 Spectrum Analysis of a Typical Commercial Load

In order to be able to conduct a harmonic power flow study in municipal areas the effect of typical single phase loads speciaily in load centers are to be rnodeled effectively. Many studies have been conducted 130-34, 401.We have used those studies and a weighted averaçinç technique in order to corne up with the following summary.

The average is weighted according to IEEE Std. 24 1- 1974 the Gray Book[40], which recomrnends the average percentage of each type of ioads in commercial buildings.

It has been shown [37] that the losses of single-phase transfomers wi increase or decrease when operating with harmonic voltages. The K-factor cdculation takes into ac- count the existence of ohmic and eddy current losses (neglecting iron-core losses), but does not address harmonic phase shifis which cm cause the change in losses due to harmonics to be either positive or negative. In addition, the K-factor emphasizes higher- order harmonics while in [37] it was shown that at low frequencies, lower order voltage harrnonics have the greatest effect on losses.

Here the results of 1361 have been used to deduce the spectmm of current wave forrn. The B-H curves are taken from [35] and the shown results are the average of fiequently used iron core materials.

In the residential areas, an increasing number of non-linear Ioads (television appliances, microwave ovens, cornputers and other electronic elements) produce harmonic distortions! at the same time they are very sensitive to harmonic distortion. In a recent study accomplished by Electricite de France (E.d.F) [30], important levels of fifth harmonic voltage in 400 kV networks were measured, and they were mainly produced by residential loads. On the other hand there is a growing trend to use energy-efficient equipment which in some cases contributes to the degradation of power quality [3 11.

5.1 Measurement of Voltage and Current Spectrums

These are the results of measurements on some of the ordinary home appliances. The device used is a Fluke 4 1B with a 1000/l mV current sensing device. In order to rnagniQ the resoiution of measurements a 5 turn coi1 has been used, therefore al1 the current and power waveforms and values are multiplied by 5 and in order to get the true values they should be divided by 5. Also note that this will not affect the harmonic measurements and graphs. The device is able to masure up to 3 ln order harmonies and the voltage, current and power measurements and spectrums are simultaneous.

The results are directly digitized and imported into the cornputer, using a 19200 baud serial connection, coupled via an optical senal port on the system.

With the introduction of new computer techniques, many of the existing software systems have been upgraded to meet the new requirements of power system operations The consequence is that some of these systems have become so complicated that the applied software design practices are inadequate to support fiuther enhancement and maintenance. As a result, replacement of the entire system becomes inevitable.

One of the major obstacles in upgrading and maintainhg the existing software systems stems directly or indüectly fiom the applied fiction-oriented software development methodologies. In these methodologies, the primary emphasis is put on decomposing and describing system fùnctionaiity. The designed software systems are usually composed of a variety of application modules. Each of them is capable of analyzing only one aspect of power systern operations and may require data input in different formats.

Integration of these application modules is usually achieved by developing interfaces among them. Such an approach might be a direct and efficient way of achieving the pre- specified goals at the beginning. However, as requirements change, a system designed in this approach may require massive reconstruction. This problem and others have largely increased the cost of the development and have made sohare maintenance quite expensive.

Another difficulty in the enhancement and maintenance of the existing power system software lies in the way the power system is modeled in the applications. Although structured prograrnming techniques have been successfully applied in some of these applications, modeling of the studied power system remains application-dependent. In other words, how the power system is represented depends on what particular application is being developed. As requirements evolve, the designed data structure may be subject to frequent changes. Some of the fimdarnental changes may propagate to a11 of the developed modules and require tremendous efforts to debug. For a large-scale software i system, this modeling method could resuit in a catastrophic consequence; the system becornes unmanageable and has to be redesigned.

To overcome these drawbacks in the curent power system software design practices. various strategies are king investigated One example is the development of a Cornmon Information Mode1 (CIM) for the EMS environment which is an EPRI sponsored project [74]. The objective of this project is to provide a standard for al1 shared EMS data, therefore making it possible for different multi-vendor applications to work together in an EMS environment. In general, the objective of these investigations can be summarized as credting an integrated software development environment capable of supporting a wide range of power system applications and allowing expansion and modification over a long period of time. Object-onented technology, characterized as a new way of thinking about problems based on real-world concepts, has proved to be an effective tool to achieve this goal.

Object-oriented technology is a new methodology of sohvare development. Its greatest benefits corne from helping developers express abstract concepts clearly and cornrnunicate them to each other. When describing the application domain based on the objects that exist in the real world, object-oriented technology stresses specieing what an object is, rather how it is used. As requirements evolve, the feature supplied by an object is much more stable the way it is used. Thus, the software systems built on an object structure are more robust in the long run. One important concept In the object-oriented paradigm is abstraction, which supports a hierarchical description of the application domain. This capability leads to an evolutionary and incremental approach for software development. In this approach. the software system can be designed with an open architecture which allows long-terrn modification and expansion.

Object-oriented technology has been extensively applied in the area of software development. Recently, application of this technology to power system software development has been addressed. The applications include database management [75-761, GUI design [77], power system modeling [78-801, power system simulations [8 1-83] and 69 educational tool development [84]. These applications stress applying object-oriented technology to a certain aspect of power system software development and most of the efforts have been focused on using object-oriented programming techniques to develop power system applications and supporting tools. However, the essence of object-oriented technology is the identification and organization of application-dornain concepts, rather than their final representations in an object-oriented programming language. In fact, object-oriented technology can be applied throughout the life cycle of power system software development, fiom analysis through design to implementation. When applied to each of these stages, object oriented technology can help solve many of the problems facing the power systern software developers.

In this chapter we explores the prospect of applying object-oriented technology throughout the development of the software systems for power system simulations. As an dlustration of the object-oriented approach, the Object Modeling Technique, an object- oriented sohare development methodology, is introduced to develop a distribution analysis system. With this technique, a Distribution Circuit Object Mode1 (DCOM) is first designed to support the incremental development of a wide range of distribution applications. Then the object-oriented prograrnming techniques are applied to implement the designed DCOM.

6.1 Overview of the Object Modeling Technique

The Object Modeling Technique (OMT), developed by Rumbaugh et al [85], is a new methodology for the object-oriented development of software systems. The methodology involves building a model of an application domain and then adding implernentation details to it during the design of a system. It consists of the following stages:

1. Analysis: The purpose of this stage is to model the real-world system so that it can be understood. Based on the problem statement, the objects and their relationships are identified using application-domain concepts. When building the model, the object- oriented analysis stresses what must be done, rather how it is done.

70 2. Design: This includes system design and object design. The system design focuses on designing the overall system architecture, while the object design involves building a design model based on the analysis model. The design model is described with computer- domain concepts, such as data structures and algorithms-

3. Implementation: The object classes and relationships developed during the object design are finally translated into a particular programming language. An object-oriented language is usually used to implement the designed system.

During each stage of this development, the OMT uses three kinds of models to describe a system: the object rnodet, the dynamic model and the fùnctional model. The object model describes the static structure of the object in a system and their relationships. The dynamic model describes the aspect of a system that changes over tirne. And the functional model describes the data transformation of the systern. In other words, the functional model specifies what happens, the dynamic model specifies when it happens and the object model specifies what it happens to. Each model acquires details as development progresses from analysis to implernentation. Although a complete description of a system requires al1 three models, only the object model concept is addressed here since it captures the essentid features of the technique.

The purpose of object rnodeling is to describe objects, which combine both data structure and behavior in a single entity. The objects with similar properties, common operations and relationships to other objects are grouped into a class. A graphic notation of the BranchDevice class is shown in Figure 6.1 From the viewpoint of object rnodeling, there are three types of relationships among the objects, that is Generalization, Association and Aggregation. Figure 6.1 Class with Attributes and Operations

Generalization or Inheritance is a powefil abstraction for sharing similarities among classes while preserving their differences. It is the relationship between a class and one or more refined versions of it. The class king refrned is cailed the base class and each refined class is called a subclass. Attributes and operations attached to a base class are inherited by each subclass. For example, BranchDevice is the base class of Line and Transformer, and Line is the base class of OverheadWire and Undergroundcable, as illustrated in Figure 6.2. Attributes like frornBus, toBus, current and operations like impedance, PowerLoss, defined in BranchDevice, are shared by subclasses, Line and Transformer. Each subclass only describes its special feature. Generalization is usudly called the "type-Of' relationship.

Figure 6.2 Generalization (lnheritance)

Association describes the physical or conceprual connection between classes. This relationship is the exact one represented in a relational database. For example, a BranchDevicc is protected by a ProtectiveDevice, as illustrated in Figure 6.3. Figure 63 Association

Associations often appear as verbs in a problern statement and contain the features of multiplicity. The rnultiplicity specities how many instances of one class may relate to a single instance of an associated class. The graphic notations of multiplicity are presented in Figure 6.4.

Figure 6.4 Multiplicity

Aggregation is the "part-whole" relationship in which objects representing the cornponents of something are associated with objects representing the entire assembly. It is a special form of association relating an assembly class to the component class.

Verbally, the aggregation cm be descnbes as " consist of" or " contain ", For example, a Substation contains such electric devices as Buses, Transformers, CircuitBreakers and Reclosers. Figure 6.5 shows this relationship.

Figure 6.5 Aggregation The OMT is a popular software engineering approach. It is especially suitable for development of large software systems. Since its introduction. It has been successfùlly applied in the software development industry. Various commercial tools are available to support this software development approach.

6.2 Developrnent of a Distribution Analysis System Using the Object Modeling Technique

The OMT has been applied to develop a distribution analysis system for distribution power system operations. The distribution analysis system was designed to provide a variety of distribution analysis for distribution dispatchers. Since distribution automation is an evolutionary process in most utilities, it is important to the develop the distribution analysis system using an approach that supports future amendment and expansion. The OMT was selected to achieve the goal of this incremental development.

6.2.1 A Distributed System Architecture

In order to meet the open system requirements, a distributed software architecture was proposed to configure the system. As shown in Figure 6.6, each component is an independent module and interacts with others through message passing.

Figure 6.6 The Proposed Distribution Anaiysis Systern Architecture

The kernel of the system is the Distribution Circuit Object Mode1 (DCOM), which is implemented as in-memory objects. The DCOM is built to support al1 of the associated distribution applications. Obviously, a unitied representation of the distribution circuit is 74 essential for achieving the high-performance system integration. The hivo types of data needed to build the DCOM are circuit description data and system operating data. The circuit description data, derived fiom the information residing in the utility distribution databases. is used to build a static distribution circuit model. The system operating data, either accessed fiom a SCADA rd-time database or specified by users for simulations, is used to describe the operating conditions of the distribution circuits. Therefore, in the case of engineering analysis, the DCOM represents the study scenarios created by the users. When applied in on-line applications, it collects real-time information from the SCADA system and reflects the current conditions of the monitored distribution circuits.

Around the DCOM is an Application Programming Interface (MI) which generates the specific data for the applications and send the analysis results back to the DCOM. The applications can not access the DCOM directly, but only through the API. Moreover, there are no direct connections among the applications. Al1 of the communications are through the DCOM. Obviously, this distributed configuration makes the future system expansion and maintenance convenient-

6.2.2 Object-Oriented Modeling of Distribution Circuits

As described in the previous section, modeling of the distribution circuit is ~f central importance to the development of the distribution analysis system. In order to support a wide range of distribution applications, distribution circuits should be modeled at a basic or tow level as well as at various levels of abstractions.

By applying the OMT, a hierarchical object model can be built to describe the static structure of a distribution circuit. This object mode1 was identified during the analysis stage and calibrated throughout the design stage. The class diagrarn of this object rnodel is shown in Figure 6.7. As shown in this figure, the proposed object model is mainly based on the physical objects that exist in a real distribution circuit, that is, electric distribution devices. Each type of device is represented as a class, which defines both the attributes and the procedures associated with this particular type of device. Figure 6.7 CIass Diagram ofthe Designed Distribution Circuit Object Model

Through data abstraction, a hierarchy of the object mode1 can be built to describe the distribution circuits at different levels. At the top level, an abstract class, Device, is identified to represent a generic distribution device. It cames only the common attributes of al1 types of distribution devices, such as device ID, phase configuration, etc. Each Device object is associated with a CraphicEIement object and a PropertyRecord object. The former defines the graphic representation of this device on the GUI, while the latter represents the device property record stored in a relational distribution database. Through these associations, the related device parameters cm be accessed from the database and the analysis results associated with this device can be displayed in the GUI. For the on-line applications, dynamic links between the Device objects and the SCADA real-time database are also required.

The second-level object modeling is based on the physical configuration of distribution circuits. Four classes are identified and derived from the base class Device. BranchDevice represents al1 types of distribution devices that link two Buses, while ShuntDevice represents al1 types of generation and consumption devices that comects to a Bus. Distribution circuits are usually equipped with the protective devices to isolate the outage and reconfigure the circuits. ProtcctiveDevices arc normally installed on BranchDevices. In the case of a ProtectiveDevice connected as a tie device, a pseudo BranchDevice is created to carry the ProtectiveDevice. Using these associations, an 76 intertwined object network can be built to match the physical configurations of the distribution circuits in the real world. In order to rneet the requirements of a wide range of applications, the concrete device classes are derived at one or more low levels, depending on how detailed the distribution circuits should be modeled. For example. Line, Transformer and VoltageRegulator are derived fiom BranchDevice, and Load, Cogenerator and CapacitorBank are derived fiom ShuntDevice. As the inheritance hierarchy deepens, the

concrete device object is described in more detail. Only the attributes and procedures specific to this particular type of device are defined in the class.

Another reiationship modeled in the DCOM is Aggregation, which describes the circuit assembly-component relationship. This relationship is simple and straightforward: a distribution circuit contains substations and distribution feeders. Each substation or distribution feeder is composed of various types of distribution devices. Usine Aggregation. the objects in DCOM can be well organized.

The proposed DCOM is only an object-oriented description of the distribution circuits for the development of our distribution analysis system. In fact, power systems can be modeled from different object-oriented viewpoints, depending on what type of software systems we are developing and what type of power systems we are modeling. For example, the object model of distribution circuits in DMS could be different fiom that of transmission networks in EMS. Industrial power systems could be modeled differently from utility power systems. However, the design criterion should be the same: the studied power system must be modeled in a way stressing what it is, rather than how it is used.

6.2.3 Implementation of the Designed Distribution Circuit Object Model Using Object-Oriented Programming

Implementation is the final stage of the sofiware development. At this stage, a particular programming language is used to implement the object model developed during the design stage. An object-oriented language is at effective tool for implementation of the designed object models. This section focuses on the implementation of the designed DCOM using Cttand the object-oriented programming (OOP) techniques [86].

The rnost important feature of an object-oriented language is the object, a logical entity that contains both the attributes and the methods that manipulate that dam Attributes and methods specific to the object are usually defined as private or protected members, which are hidden fiom other class of objects. Access to the private attributes is normally accompIished through the public functions. This information hiding mechanism is referred to as encapsulation. Encapsulation prevents a program fiom becoming so interdependent that a small change may have massive rippling effects. In this way, the implernentation of an object cm be changed without affecting the applications that use it- The class definition of BranchDevice is given in Figure 6.8, where both data and procedures related to this object are defined in the class. class BranchDevice : pub1ic Device protected: Bus* fromBus; // Pointer to from-bus Bus* toBus; // Pointer to to-bus M3.u 1 current; // Current vector (fromBus->toBus)

...m. public: virtual M3x3 Impedance( )=O; !/ Impedance calc. method M3 x1 PowerLoss( ); // Powerloss calc. method

Figure 6.8 Example of Class Definition

Object-oriented programming languages provide strong support for the notation of inheritance. This mechanism allows a hierarchy of classes ro be built, moving fiom most general to most specific. As show in Figure 9, class Line and class Transformer are derived from the base class BranchDevice. These derived classes inherit al1 of the data 78 and code from the base class, such as fromBus, toBus, current and PowerLossO. Only specific data and code are added to define the derived class. This feature makes it possible to reuse code.

However, what makes the inheritance really powerful is an OOP mechanism, polymorphism which is also referred to as "one interface, multiple methods". It allows the the type of concrete objects involved. For example, a pure virtual hinction, ImpedanceG, is defined in the abstract class without the actual implementation. This hinction is actually impiemented by ai1 of the subclasses of BranchDevice with diffèrent methods; the line impedance is calculated according to line size and physical configurations and the transformer impedance is calculated based on the short-circuit impedance, tap ratio and grounding type. This mechanism makes it possible to develop the distribution applications, such as load flow study, at a higher level without dealing with the detailed model of the distribution circuit components. For instance, when calculating impedance, it is even unnecessary to know whether the branch is a line or a transformer, since the pure virtual hction BranchDevice::Impedance~ will be automaticaily overloaded at nin time by either tine:tlmpedanceO or Trnnsforrner::lmpedance(), depending on the type of the branch. Furthemore, this mechanism effectively restricts or minimizes the effects of the model changes on the developed applications. If we find it necessary to distinguish the overhead lines fkom the underground cables because of their difference in irnpedance computation, this change can be made by simply deriving the two subclasses and overloading the virtual function impedanceo within the derived classes. The load flow application may not require any changes, since it only handles their base class BranchDevice. class Line : public BranchDevice

protected: LineSize size; // Line size LineConfig config; // Line physical config...... public: M3x3 Impedance( ); // Line impedance calc. Method

class Transformer : public BranchDevice

protected: double tapRatio; /nap ratio complex z; //Short-circuit impedance Gtype groundingType; //Grounding type .....-. public: MSx3 Impedance( ); // Xfmr impedance calc. Method ...... -

Figure 6.9 Example of Inheritance Implementation

An Association in the object mode1 can be implernented using rnany approaches. Among these approaches, buned pointers are the easiest to implement. In this approach, an Association is simply implemented as an attribute in each associated object. containing a pointer to the related object, or to a set of related objects. For example, each Device object contains a pointer to its GraphicElement in The GUI and a pointer to its propertyRecord in the database, as itlustrated in Figure 6.10. Normaily, Associations are implemented in both directions to support bi-directional traversais.

An Aggregation cm be implernented using a collection class object, such as a dynamic array or a list. With the collection objects, a container object can group and manage al1 of the component objects. As shown in Figure 6.1 1, a generic List object based on the template technique is used to assemble various distribution devices in a container object, DistributionFeeder. class Device { protec ted: DevicelD id; // Device iD GraphicElement* graphicElement; //Association with //GUI element Property* propertyRecord; //Association with //database record ...*.... public: DeviceID ID( ) { return id;)

Figure 6.10 Example of Association Implementation

Normally, a set of methods are provided to access and manage the component objects in a container object.

c fass DistributionFeeder { private: List allBuses; // Bus container List alIlines; // Line container ..*-... Public: DistributionFeeder ( ); //Constmctor -DistributionFeeder ( ); //Destmctor Bus* Bus(Device1D); // Accessing bus based on ID

Figure 6.1 1 Example of Aggregation Implernentation Chapter 7 Case Studies

In this chapter two different cases fiom different perspectives will be studied-

The first invofves an industrial plant with a hannonically rich environment due to the abundance of the DC drives. The main goal was to increase the existing power factor to avoid excessive penalty charges paid to the utilities, but the presence of harmonies in the system prevented the utilization of conventional static (VAR compensation) power factor correction methods.

The second case is viewed from the utilities point of view (in contrast to the first one which is fiom the end user's view point), and it involves the investigation of a possible power quality pollution system. The goal is to investigate if the injected harmonic levels in the utilities network exceed the recornmended thresholds. The concem is due to the major PWM rectifiers in the casino environments which cause the injection of considerable arnounts of triplen hannonics. (For the amplitude of the mentioned harrnonic orders please refer to chapter 5 , measurement on a PC.)

For the second case three series of measurements were conducted, measurements on the temporary casino, new casino site before and after inauguration.

7.1 Case Study No. 1: Kautex-Textron

At the request of the Kautex-Textron Windsor Plant, a study of the electrical system power factor and harrnonic analysis at the blow molding machines has been carried out by Wilson, Dario & Associates during October and November 1998, in order to decrease the penalty charges and improve plant power quality.

The scope of work included the measurement of the power quality at each machine and an analysis of the harmonic contents and detemination of the best power factor (P.F.) correction means and methods. Alternatives were to be identified and analyzed to

82 determine the optimal sizes and locations for the new power factor correction and power quality improvement systems.

Analysis of the rewrded data confirmed that presence of harmonics currents injected by the machines which prevent the utilization of ordinary power factor correction capacitor banks. The data established the need for a method of either eliminating the most signifiant harmonics or the application of more mgged P.F. correction capacitor banks.

The studies showed that a combination of tuned capacitors at the larger machines and additional units at the main substation switchboards would be the most economic method to recti@ the problem.

7.1.1 Plant Electrical Supplies

The Windsor plant of Kautex-Textron is supplied from the WUC - 55M25 transmission line aIong Deziel Drive at 27,600V voltage level. The metering facilities of the Windsor Utilities Commission (W.U.C.) are situated at the 27,600V side.

Appendix D drawing is the simplified single line diagrarn of the existing plant distribution system.

There are four voltage levels in the plant, 27,600V which is the incoming level, 6OOV which is the plant distribution level, the 4001240 V level which is the blow molding machines voltage level, and the 208/120 V for general and administrative loads.

In order to isoIate the major loads from the other applications, transfonners TA and TB are used for the blow molding machines, chiller and compressed air facilities. Transformer TC has been designated for the general and administrative loads. This division has the advantage of isoIating the main harmonic generating apparatus fiom the others, therefore avoiding the interference of these networks.

The current W.U.C. billing methods apply a penalty for power factors Iess than 0.9 (90%). This is dune by adjusting the actual demand kW to a value that is equivdent to a 90% power factor. The applicable demand charge is then applied to the corrected demand KVA.

7.1.2 Blow Molding Machines Measurements Summary

Measurements were taken during normal blow molding machines operating cycles using an industrial power quality measurement device and harrnonic analyzer. (ACE 2000)

Measurements were camied out on al1 machines to justie the installation of capacitor banks or filters on each machine.

During our measurements a series of other harmonic related problems, such as excessive high temperatures in feeding transformers, melting of contactor coils insulation, heating of power distribution cables and excessive voltage drop were observed. These are additional effects of poor characteristics of voltage and curent waveforms due to harrnonics.

Tables (7.1 ) to (7.8) are the surnmaries of measurements for each machine. In Appendix A, a complete report of measurements on two typical machines is presented.

The measurement results completely back up Our simutation results.

7.1.3 Proposed Alternatives

In this section different alternatives will be analyzed regarding their feasibility, cost and efficiency of the solutions.

Adding capacitor banks to correct the power factor is the conventional method but, due to the nature of the loads in KAUTEX-TEXTRON plant it can't be done directly. The problem arises from the presence of harmonics in the system. Harmonic currents see the changing power factor correction capacitors as the least impedance path and flowing in that direction they blow out hses of the capacitor banks.

The second alternative would involve the application of harmonic filter(s) at the injection point(s) and correction of P.F. individually using ordinary capacitor banks on the secondary side of the transformer The advantages of this alternative are as follows:

better total harmoaic distortion (THD%) characteristics

a seIective high power factor (according to the settings of individuai banks)

less problems at the capacitors due to better elimination of the fifih harmonic

increasing the efficiency of distribution system by reduction of losses

increasing the efficiency by compensating some of the transformer losses (due to reduction of flow of reactive power through transformers)

increasing the lifetime of step-down transformers and distribution cables by supplying the reactive power needed at the load.

The disadvantages of this alternative are:

high costs of installation

high costs of maintenance

installation problems regarding the physical space available at each machine

high spare capacity

Long delivery time for manufacturing of the reactors

7.1.3.3 Alternative #3:

This alternative involves the application of harmonic filter(s) at the injection point(s) and correction of P.F. individuaIly using ordinary capacitor banks on the primary side of the step-dom transformers.

The advantages of this alternative are as follows: a selective high power factor (according to the settings of individual banks)

smaller unit sizes (due to higher voltage rating)

increasing the efficiency of distribution system by reduction of losses

The disadvantages of this alternative are:

persistence of transformer voltage drops and losses

high costs of instailation

high costs of maintenance

installation problems regarding the physical space available at each machine

high spare capacity

Long delivery time for rnanufacturing of the reactors

7.1.3.4 Alternative M.-

The fourth alternative would involve the application of harmonic filters on the secondary side of the transformers and the P.F. correction means centrally at the switchboards 'A' and 'B'.

The advantages of this alternative are as follows:

Moderate P.F. correction

Ease of maintenance

The disadvantages of this alternative are:

providing space at the substation providing comection feeders for the capacitor units

persistence of distribution iosses

7.1.3.5 Alternative #5:

The fifth alternative would involve the installation of active filters in order to eliminate the harmonies (by injecting them iipon the demand of the loads) and then using standard capacitor banks to bnng up the plant power factor (which can be done on individual machines or centraily at the substation).

The advantages of this alternative are as follows:

the best resulting THD% due to simultaneous elimination of up to 4 harmonic orders

The disadvantages of this alternative are:

approval of some of the units are needed by CSA

high costs (initial price and maintenance)

7.1.3.6 Alfernative #6:

The hybrid solution which is a combination of first and third alternatives. In this alternative the tuned capacitor banks are instailed for the blow molding machines 1, 2 and 5 and the rest of the plant reactive power will be compensated at the substation

The advantages of this alternative are as follows:

the most economical solution

optimized on-the-floor activities (regarding the installation of units at the machines)

availability of the feeders at the substations The disadvantages of this alternative are:

Instailation of the units for larger machines

Alternatives including a big central system of power factor correction are not feasible due to the lack of feeders and installation space at the switchboard station. It has ken cakuIated that a central capacitor bank in the order of 4,000 kVAr would be required at peak loads.

Alternatives involving the installation of filters andor capacitor banlcs on the prïmary side of machines step-down transfomers benefit smaller unit sizes but will not be favored due to:

approximately the same installation costs as the secondary units

persistence of transformer losses due to flow of reactive power through the transformer resulting in low voltage levels to the machine

(in case of primary side filters) persistence of transformer losses due to the most signi ficant harmonies

Alternatives involving the installation of filters and/or capacitor banks on al1 the machines are not economically justifiable due to the long pay back periods for the smaller machines and installation constraints at each machine.

The most economical alternative is No. 6, which is a hybrid solution providing the desired power factor and the minimum installation work load in the plant. At the same time it rnay be possible to avoid replacement of machine No. 5 step-down transformer, if faster cycle times are implemented, by compensating for the reactive power on the secondary side of the transformer. This optimum solution involves the installation of three 400 kVAr tuned capacitor banks for machines 1, 2 and 5 and an additional two 700 kVAr tuned capacitor banks at the main substation, one for switchboard 'A' and the other for switchboard 'B'.

Since, the installation of hmonic filters and the impact on the plant power factor will Vary based on the effectiveness of the equipment purchased, it is recommended that the installation be conducted in two phases.

The first phase would involve the installation of tuned capacitors at machines 1, 2 and 5. After these units have been instailed, their affect on the plant power factor and power quality should be measured.

The final design of the units at the main substation may have to be re-evaluated after the interim measurements are analyzed.

The following table sumrnarizes the alternatives and their merit and demerit points.

Another issue that was addressed was the installation problem, resarding the best location for positioninç the capacitor banks.

Table 7.7 Summary of proposeci alternatives 7.2 Case Study No. 2: Windsor Casino

As a part of the studies regarding the effect of harmonics on electricai power distribution systems, a series of harmonics related analyses were conducted on one of the classicd distribution system polluters, a concentration of pulse width modulation and electronically switched rectifiers. As exmined in chapter 5 this class of harmonic generating sources consists of electronic devices power supplies. They generate high contents of third order and other triplen harmonics. Being of the zero sequence, no matter how balanced the three phase distribution system is, they add up algebraically in the neutral of the distribution transformer (usually with grounded wye secondary configuration) and propagate into the power system. In the case of delta configuration in the primary side of the distribution transformer triplen order hmonics circulate in those windings and having a higher fiequency than the fundamental will cause excessive heating of the transformers, causing additional aging and possibility of insulation breakdo wn.

Casinos are amongst the ~O~O~OUSharmonics injection units in power industry. Accumulation of small single phase electronic devices (slot machines, .. .) will introduce high levels of triplen harmonics.

The goal of our studies was to investigate the amplitude of injected harmonics into the Windsor Utilities Commission (W.U.C.) power distribution network and to verify if the recommended thresholds are violated.

The studies showed that due to several stages of voltage reduction (step down) the readings at the Point of Cornmon Connection (PCC) were not significant (in the measurement time fiames).

It should be mentioned that al1 measurements were performed during the off peak hours of operation of the facilities and only snap shots of the waveforms were sampled. Our measurements were greatly limited by the availability of the sites. type of measurement equipment and level of access due to security issues.

95 A conclusive study not only should cover the intemal distribution system in more detail but also should be extended to months of off-peaklon-peak measurements. The existing energy meters in the new Casino Windsor site are capable of such performance provided that analysis software king available.

7.2.1 Old (Temporary) Casino Windsor

The temporary Windsor Casino was supplied from the WUC - 25M8125M12 underground cables dong the Pitt Street at 27,600116,000 V voltage level and 2SM10 (overhead) transmission lines along Janette St. at the same voltage levels.

Three transformers are on the site:

3307 and P709 fed fiom either 25M8 or 25M12 through 410 Al. XLPE cables.

P746 fed from Crawford transformer station through 500 MCM Al. Conductors which mostly fed parking lights (HID types).

Voltage levels and currents are given in summary tables 7.8 to 7.15 and voltage, current and power waveforms in figures 7.1 to 7.8.

Some main points are to be clarified:

Current transducer was not an industrial one therefore the measurements were performed on the secondary side of the transformers and always on one of the sets of outgoing cables. True current values should be calculated by multiplying the measured values by the number of the cables.

In these cases the measured power should also be multiplied by the number of cables.

In some measurements the power is measured as a negative value which is the case when the current sensor (being a directional sensor) is inserted backwards. 4. The first two transformers were feeding the Casino installations. Transformer P709 was supplying other transformers which were not accessible for security rasons.

5. It is worth mentioning that the transformer with 208/120 V secondary voltage level shows noticeabie current THDs.

6. A11 transformers are star-delta connected therefore eliminating the triplen harmonies in the secondary. Measurement: Windsor Ternporary Casino Date: 7 July, 1998 First Transformer: P709 fed fiorn feeder 25M8.

The Windsor Casino site is supplied fiom the WUC - 55M 1 onginated fiom Walker Road T.S. #1 and transmission at 27,600V voltage level and 15M8 supplied fiom Essex T.S. at the same voltage level. The metering facilities of the Windsor UtiIities Commission (W.U.C.) are situated at the secondary side of main transforrners T-A, T-B and T-C in the basement of the facility. The units are sarnpling the voltage and current using measurernent voltage and current transformers and for billing purposes, there fore (using two wattmeter-Amon's method) there are two phase to phase voltages and three line currents sampled.

Appendix D drawing shows a simplified single line diagrarn of the existing plant distribution system.

There are four voltage levels in the plant. 27,600V which is the incoming level, 4160V which is the generators voltage levels, 600V which is the facilities distribution level, and the 2O8/1 20 V for general loads.

Two sets of measurements were performed on July 6, 1998 at 8:30 A.M. (before opening of the facilities to the public) and August 17, 1998 at 8:20 A.M. afier inauguration of the Casino site.

Currents measurements were performed on the secondary side of 300/5 A current transformers and to improve the resolution a 10 turn coil was used for the first sets of measurements and unfortunately for the second set of measurements the coil was not available, therefore for the first set the true current is 6 times the measured values and for the second set 60 times. Voltage measurements were performed on the secondary side of an open delta -open wye set of potentid transfomers with 120 V phase to neutral voltage levels. Available only for phases A and C.

Measurements were taken during usual off-peak hours of the Casino due to the availability of W.U.C. personnel. Power quality measurement device and harmonic analyzer was a single phase Fluke 418 type with the ability to store up to 8 snapshots of the measurements and a 1000A current probe.

The following rneasurements show the voltage. current and power for two phases A and C with their pertinent phase voltages and phase current B with one of the other phases voItages.

The sarne format has been kept to insure the consistency with the other parts of measurements. 7.2.2.1 Ne irf WindiFor Casino Measuremenrs before Inaupuration: Measurement: Casino Windsor Date: 6 July, 1998, 8:30 A.M. Transformer A.

Table 7.32: Sumrnary of the measurement results 73 Conclusion and Suggatcd Fortber Studies in these studies a variety of loads have ken simulated (using M.ATL\B) and their harmonic contents have been analyced. Measurements were used to back up the simulation results. A rrsourceful library of current and voltage spectmns has been developed as a basis for Mer sndies.

An Object-Onented powu-flow software has hem developed and tested niccessfiilly on IEEE 14 bus system, ptoving the merits of this new software development methd. It bas been compared to a powerfiil cornmercial software (EDSA).

The measurernents pedormed on casino sites have show that harmonies injected in the Windsor Utilities network were negiigible (a! the snapshots measurernents taken).

Although not accurate for detailed engineering, current injection method is used for case study No. 1 to justify the meanirnaeats. The next steps in this ongoing project will be to perform another meanuement on the dences and design dehined fapacitor banks (combination of capacitor banks and hannonic filters) for the wbole plant to b~gthe power factor over WhImeL

It is proposed that furtôer studies and analyses to be conducted in Win- area which plenty of plants with induction and arc runiaces exist. As suggested by Sirinivasan [17] game plans can be developed to isolate customer and utilities side of the pwer distribution systern, the psibilities of adjusting the rates for power spem polluters could aIso be investigated [I 8).

Hamonics are increasingly causing probiems in industrial areas and investigating economical methods of identification and eliminatioa of them is highly sugeested.

The propagation of di fferent harmonic orders in industriai or commercial environments and their effects are highly in demand and are mostly case by case studies. Appendix A Case Study No. !
