  • Introduction to Power Quality
    CHAPTER 1 INTRODUCTION TO POWER QUALITY 1.1 INTRODUCTION This chapter reviews the power quality definition, standards, causes and effects of harmonic distortion in a power system. 1.2 DEFINITION OF ELECTRIC POWER QUALITY In recent years, there has been an increased emphasis and concern for the quality of power delivered to factories, commercial establishments, and residences. This is due to the increasing usage of harmonic-creating non linear loads such as adjustable-speed drives, switched mode power supplies, arc furnaces, electronic fluorescent lamp ballasts etc.[1]. Power quality loosely defined, as the study of powering and grounding electronic systems so as to maintain the integrity of the power supplied to the system. IEEE Standard 1159 defines power quality as [2]: The concept of powering and grounding sensitive equipment in a manner that is suitable for the operation of that equipment. In the IEEE 100 Authoritative Dictionary of IEEE Standard Terms, Power quality is defined as ([1], p. 855): The concept of powering and grounding electronic equipment in a manner that is suitable to the operation of that equipment and compatible with the premise wiring system and other connected equipment. Good power quality, however, is not easy to define because what is good power quality to a refrigerator motor may not be good enough for today‟s personal computers and other sensitive loads. 1.3 DESCRIPTIONS OF SOME POOR POWER QUALITY EVENTS The following are some examples and descriptions of poor power quality “events.” Fig. 1.1 Typical power disturbances [2]. ■ A voltage sag/dip is a brief decrease in the r.m.s line-voltage of 10 to 90 percent of the nominal line-voltage.

    CHAPTER –7 CONTROL AND PROTECTION OF HYDRO ELECTRIC STATION 7.1 Introduction 7.1.1 Control System The main control and automation system in a hydroelectric power plant are associated with start and stop sequence for the unit and optimum running control of power (real and reactive), voltage and frequency. Data acquisition and retrieval is used to cover such operations as relaying plant operating status, instantaneous system efficiency, or monthly plant factor, to the operators and managers. Type of control equipment and levels of control to be applied to a hydro plant are affected by such factors as number, size and type of turbine and generator. The control equipment for a hydro power plant include control circuits/logic, control devices, indication, instrumentation, protection and annunciation at the main control board and at the unit control board for generation, conversion and transmission operation including grid interconnected operation of hydro stations including small hydro stations. These features are necessary to provide operators with the facilities required for the control and supervision of the station’s major and auxiliary equipment. In the design of these features consideration must be given to the size and importance of the station with respect to other stations in the power system, location of the main control room with respect to the equipments to be controlled and all other station features which influence the control system. The control system of a power station plays an important role in the station’s rendering reliable service; this function should be kept in mind in the design of all control features.

Improvement in the efficiency and cost in the high frequency inverter will play a major role in its applications like electrical vehicles (EV). A high voltage IGBTs are used in inverters to bear the voltage peaks across the IGBT switch at the turning off period of switch. By decreasing the value of voltage peak, can reduce the voltage rating of IGBT switch, by which the system cost will decrease. Decreasing the value of voltage peak can be achieved by decreasing the inductance of the inverter circuit which includes turned on switch inductance, DC link capacitors inductance and connecting wires inductance. By replacing the connecting wires with a laminated busbar in an inverter, the inductance value of a connecting wires can be reduced. Laminated bus bar is a parallel conductor plates separated by a dielectric medium. Upper plate is considered as positive plate and lower plate is a negative plate. In this paper it gives a detailed information about laminated busbar with different designs, using different conductive materials, their calculated inductance in ANSYS 3D FEM software and concluding with suitable laminated busbar for high frequency inverter. l 1 = l s + l bc + l ca. (2) 1 Introduction Where, ls is a connecting wires inductance of the H- bridge inverter, lbc is an internal inductance of IGBT Laminated busbar is a device used to reduce or include the switch Q1 of an H- bridge inverter and lca is an internal inductance in the power electronic circuits.
