2.4 Long‐Term Energy Yield Assessment for Operating Wind Farms

The long‐term assessment of the energy production gives an outlook on the expected long‐term energy yield of operating wind farms. It is based on a detailed analysis of the production data from the past operating period of the wind turbines. The short‐term production data is correlated with verified long‐term wind data from different sources. We have performed this kind of service for almost 100 wind farms with a total capacity of roughly 1 500 MW.

2.5 Wind Resource Assessments and Site Suitability Studies for Pro‐ posed Wind Farms

Based on solid experience in wind resource assessments, the following steps are per‐ formed within the framework of an energy yield assessment for a proposed wind farm:  Evaluation of on‐site wind measurement data by means of specific procedures de‐ veloped by Deutsche WindGuard, including a detailed check of measurement data (e.g. in‐situ calibration of the utilised cup anemometers in order to evaluate their consistency during the course of measurements, correction of mast disturbance on anemometer readings, filling of data gaps by specific correlation methods, correction of dynamic anemometer characteristics)  Long‐term correlation of on‐site wind measurement data by means of specific pro‐ cedures developed by Deutsche WindGuard, including verification of the available long‐term data by detailed comparison of different data sources (e.g. reanalysis data, data from meteorological ground stations)  Flow modelling, optional application of three‐dimensional flow models (CFD)  Minimisation of the overall uncertainty of the by deter‐ mining an optimised weighting of the available data sources using iterative proce‐ dures  Analysis of assumed wind turbine power curves for the energy yield calculation; harmonisation of power curves and predicted wind conditions regarding the utilised cup anemometer types  Detailed uncertainty analysis and risk evaluation  Assessment of the technical losses (e.g. losses due to technical non‐availability of the wind turbines, electrical losses, site‐specific calculation of icing losses in cold climate based on meteorological data, etc.)  IEC site classification (i.e. site suitability study), including evaluation of average and extreme wind conditions, flow inclination, vertical , air density, turbu‐ lence conditions (incl. additional turbulence intensity due to wind turbine wakes), etc.  Specifically developed know‐how in the field of offshore wind energy  Detailed documentation and bankable reports including solid assessment of risks and technical loss factors  Development and realisation of supplementary energy yield assessment techniques, partially with market leadership of DWG: detailed time series based wind farm oper‐ ational data evaluation, post construction energy yield assessment, calculation pro‐ cedures for loss assessments due to grid constraints, calculation procedures for time series based calculation of energy yield compensations due to offshore grid delay

An overview of the energy yield assessments of onshore sites performed by Deutsche WindGuard is shown in the table below. So far, onshore energy yield assessments have been performed for an overall installed capacity of more than 20 500 MW.

2.8 Calculation of Noise Emission in the Vicinity of Proposed Wind Farms

Deutsche WindGuard Consulting GmbH is accredited for calculation of noise emission in the vicinity of wind farms since 2012. Its staff members, however, have several more years of experience in wind turbine noise issues. In the course of wind farm planning, developers and responsible authorities need detailed and trustworthy information about the expected noise emission in the vicinity of wind turbines. Consequently, calculation of noise propaga‐ tion and emission levels at receptor locations around a designated project site forms an es‐ sential part of the approval process. In case the emitted noise of a commissioned wind farm exceeds the legal noise emission limits, individual turbines may have to be de‐rated in pow‐ er or shut down for particular time periods. Hence, the imminent loss of income for the op‐ erator strengthens the necessity of reliable noise emission predictions in the planning phase of wind farms. Wind turbine noise prediction is a complex topic. The sound power level of a wind turbine usually increases with wind speed / produced electrical power. Apart from aerodynamic noise from the rotor blades, mechanical noise can constitute another source of noise emis‐ sion. On the other hand, the noise emission perceived at a receptor location depends also on site‐specific conditions. In this context, we generally analyse the turbine locations and all relevant receptor locations during a site inspection. Laws and noise regulations differ from country to country and customers are often uncer‐ tain, how to meet these requirements. In some countries, the noise emission limits to be ob‐ served depend on how nearby buildings or structures are utilised (residential areas, indus‐ trial areas, etc.). In other countries the acceptable noise emission levels are associated to the level of the (natural) ambient noise at the receptor locations. We can find solutions and pro‐ vide concepts also in complex situations. After commissioning of a wind farm Deutsche WindGuard can also verify the actual noise emission by noise measurements on site (see chapter 6.2).

Deutsche WindGuard offers:  Obtaining of all documents needed for the approval process according to TA Lärm (Ger‐ many), ISO 9613‐2 (international), or other country‐specific guidelines  Noise calculations based on wind turbine specifications given by manufacturers or inde‐ pendent noise measurement laboratories  Calculation of sound propagation and noise emission levels  Development of concepts to reduce noise emission when exceeding the critical limits

2.9 Determination of Shadow Flicker Impact in the Vicinity of Proposed Wind Farms

Shadow flicker is one of the most important “optical emissions” from wind turbines, which must be considered during the planning phase. Rotating rotor blades cause a flashing effect by periodical blocking off the sunlight, which may cause disturbance of residents in the vicinity of wind farms. For this reason, the determination of optical emissions from wind turbines forms an essential part of the approval process in the planning phase of wind power projects. For the calculation of shadow flicker impact, factors that must be taken into account are wind turbine hub height and rotor diameter, position of the sun and the geometry be‐ tween the turbine and receptor locations. The main task is to determine the periodical shadow flicker at given receptor locations as a function of time (i.e. time of day, time pe‐ riods per month, etc.) and to provide the relevant statistics of shadow flicker periods to be utilised for the juxtaposition with the corresponding limits given by the authorities. As part of a mandatory site assessment, our experts will analyse the proposed locations of the wind turbines and all relevant receptors.

Deutsche WindGuard offers:  Determination of the maximum possible (astronomical) shadow flicker periods (worst case) and the probable time periods (considering cloud cover, etc.)  Graphical and calendric description of the shadow flicker periods at given receptor locations  Acquisition of all documents needed for the approval process, including the shadow flicker calculation  Calculation of the required turbine shutdown times in order to adhere to the limits set by authorities  Development of shutdown concepts for wind turbines to be programmed into the turbine’s control systems

2.10 Visibility Analysis

Visual impact of a wind farm is a computer based environmental impact assessment, which can be done in an early planning phase. It helps planners and authorities to in‐ crease the acceptance level of a wind farm project as it shows potential significant visual impacts. Furthermore, it helps the wider audience of an environmental statement to un‐ derstand the nature of these visual impacts through illustration. Forests, villages and other blocking elements can be included in the visual impact assessment. Up until now, we have performed visibility analysis for proposed wind farms with a combined capacity of 100 MW. Deutsche WindGuard offers:  Production of maps showing absolute and relative visibility of parts of or the whole planned wind farm (optional visibility: total height or hub height)  Production of a photomontage showing the planned wind farm in an almost realistic view, with help of digital terrain models and digitalised wind turbines montaged in a landscape photo

2.11 Ice‐Throw Risk Analysis

In the course of wind farm planning, developers and responsible authorities need de‐ tailed and trustworthy information about the expected probability of ice impact in the vicinity of wind turbines. In the absence of a legal regulation Deutsche WindGuard developed a simulation based on an empirical database to calculate the individual risk to be struck by ice‐throw in the vicinity of a wind turbine. “Individual risk” is defined as the probability for one person to be struck by ice‐throw of a piece of ice specified in mass and dimension if this person stands still and unprotected on a designated spot for one year.

Deutsche WindGuard offers:  Probability distribution of ice‐throw risk of a stopped wind turbine  Probability distribution of ice‐throw risk if the pieces of ice are thrown out from the tips of the blades (usually this results in a stop of the turbine, because of imbalances)  Probability distribution of ice throw risk of a turbine in idle mode  Calculation of the maximum ice throw distances for different wind speeds

We have performed risk analysis for ice‐throw for almost 160 turbines.

4.4 Thermographic Boundary Layer Visualisation of Wind Turbine Rotor Blades in Operation

The location of the laminar‐turbulent transition has a direct effect on the performance of an air foil. Thermography has been a valuable tool for boundary layer visualisation for several years in both wind tunnels and other applications. The use of high‐speed, high sensitivity thermal imaging systems in combination with long focal length lenses allows applying this method to megawatt range wind turbines in operation, in which the inves‐ tigated rotor blade and the measurement position are several hundred meters apart. Measurements deliver qualitative information regarding the transition location along the rotor blade, and allow comparisons between different operational states and condi‐ tions.

WindGuard Offers: A high speed actively cooled 640x512 pixels InSb‐focal‐plane‐array with a thermal reso‐ lution better than 0.025 K is used together with a telephoto lens to acquire high resolu‐ tion thermal images of rotor blades in operation. The laminar‐turbulent transition and laminar flow regions are visible on the images. The reduced field of view requires stitch‐ ing several images to obtain a single image of one rotor blade. Since incorporating this service into the WindGuard Universe, we have performed four measurements in Germany and four in Denmark.

4.5 Analysis of Wind Farm Operational Data

The data stored by the wind turbine or wind farm control system (SCADA) has been identified to be a valuable source of information for many purposes. Based on SCADA data, different analyses are possible and offered by WindGuard:

 Error statistics and fault analysis  Evaluation of wind turbine availability and associated energy losses  Evaluation of “true” wind turbine availability (independent from manufacturer’s definition availability)  Definition of technical and energetic availability  Evaluation of wind turbine non‐availability in terms of energy loss  Analysis of wind turbine control parameters, e.g. pitch angle, rotor speed, tempera‐ ture, phase shift between voltage and current  Relative power performance analyses  Long‐term energy yield assessments

5 Wind Tunnel Centre

Optimal conditions for measurements, tests and research for the wind industry and far beyond: that’s what WindGuard’s Wind Tunnel Centre stands for. The facilities for mul‐ tiple fields of application stretch out around 2.500 square meters. The Wind Tunnel Centre opened its doors in 2003 to provide high precision anemome‐ ter calibrations for the wind energy industry. With these calibrations, the accuracy of wind measurements improved significantly. As a 1 % deviation of the measurement from the actual wind speed are reflected in 3 % energy yield loss, this makes a huge dif‐ ference.

5.1 Anemometer and Wind Direction Sensor Calibration and Classifi‐ cation

Deutsche WindGuard is the leading expert when it comes to the calibration of anemome‐ ters and wind direction sensors. Our wind tunnel centre consists of four calibration wind tunnels and one climatic wind tunnel to conduct research on the process of icing on anemometers and wind direction sensors. Deutsche WindGuard also operates a re‐ search wind tunnel with the ability to vary the ambient pressure, respectively air densi‐ ty and temperature at the same time. This further expands WindGuard’s ability to assess anemometer performance and conduct anemometer classification, meeting IEC 61400‐ 12‐1 requirements, even in the newest 2016 revision.

 Four wind tunnels specifically designed for anemometer calibrations  Accredited by Deutsche Akkreditierungsstelle (DAkkS) for the calibration of ane‐ mometers according to DIN EN ISO/IEC 17025  Accredited for flow speeds from 0.5 m/s up to 38 m/s  Recognized by MEASNET  National Metrology Institute of Germany (PTB) is using wind tunnel Varel 2 as one facility to embody the German national standard for the flow speed of air. The na‐ tional standard of flow speed is hence realized through a permanently installed; PTB owned and calibrated, Laser Doppler Anemometer (LDA) within our test section of wind tunnel Varel 2  First ever accepted calibration laboratory for anemometer calibration by the IECRE  Own open field test facility for anemometer testing and classification  Classification of anemometers according to IEC 61400‐12‐1

ReferenceList_DWG_2016‐12_V04_final 61 / 89

Reference List of Deutsche WindGuard

Deutsche WindGuard is also accredited to perform calibrations of the flow direction (horizontal and vertical flow). Therefore we are able to offer calibration of wind direc‐ tion sensors (variation of relative horizontal flow angle) and 2D as well as 3D sonic an‐ emometers (variation of relative horizontal‐ and vertical flow angle). This is indispensa‐ ble when a tractable wind tunnel calibration of wind direction sensors is required.

 Accredited by Deutsche Akkreditierungsstelle (DAkkS) for the calibration of wind vanes according to DIN EN ISO/IEC 17025  Wind direction sensor calibration according to IEC 61400‐12‐1, Annex N  Variation of rel. horizontal flow direction at a range of 0 … 360 deg (continuous or stepwise)  Variation of rel. inclination flow direction at a range of ±30 deg

6 Measurements on Wind Turbines

6.1 Wind Turbine Power Curve Testing

Deutsche WindGuard is accredited as a testing laboratory for the measurement of wind turbine power curves. Apart from measurements according to accepted standards, Deutsche WindGuard has developed some additional methods to verify the power per‐ formance of wind turbines, in part without application of a costly met mast. The power performance of wind turbines often deviates from the guaranteed power curve or from that power curve, which is measured at the same type of turbine under other conditions. Furthermore, the wind turbine power performance is often not opti‐ mised. The verification of power curves in wind farms is a service that is increasingly asked for by wind farm operators in order to verify the performance guaranteed by the manufacturer or to identify potential for optimisation. So far, Deutsche WindGuard has analysed power curves of wind turbines with an overall power of around 600 MW in wind farms with a total capacity of about 6 GW. The main characteristics of our services are:  Accredited according to DIN EN ISO/IEC 17025:2005 for power performance meas‐ urements according to IEC 61400‐12‐1 Ed.1, draft of IEC 61400‐12‐1 Ed.2, IEC 61400‐12‐2 and the German Guideline TR2 (FGW) and accepted by MEASNET  Extensive experience with new technologies, like application of nacelle LiDARS, scanning LiDARs on the tower foot and numerical site calibrations  Efficient verification of each wind turbine within a wind farm by application of Inte‐ gral or Relative Power Curve Analysis  Results are well accepted by wind turbine manufacturers  Technical elaboration of guarantees regarding the verification procedure, fulfilment criteria and modes of payment  Experience with certification measurements at wind turbines from 30 kW to 7.5 MW  Hired by different wind turbine manufacturers for advice, research and development in the field of improving procedures for power performance testing: investigation of influence of meteorological conditions on power performance, new LiDAR applica‐ tions, application of nacelle anemometry, application of numerical site calibration, improvement of terms of power curve warranties, uncertainty analysis, uncertainty reduction by multiple turbine testing

6.2 Acoustic Noise Measurements on Wind Turbines

Deutsche WindGuard Consulting GmbH is accredited for acoustic noise measurements since 2012 and achieved conformity with the Fördergesellschaft Windenergie und an‐ dere dezentrale Energien (FGW e.V.) requirements for acoustic noise measurements on wind turbines.

Standardised acoustic noise measurements on wind turbines are usually performed ac‐ cording to IEC 61400‐11. Major quantities to describe the noise characteristics of a wind turbine are the overall sound power level, so called “tonality” (mostly due to mechanical noise components) and impulsivity (periodical sound power fluctuations). In individual cases, analysis of low frequency noise is of interest. We offer acoustic noise measure‐ ments according to the state‐of‐the‐art standards and procedures as well as specific analyses requested by our clients. In general, standardised noise measurements are also part of the turbine certification process.

The dominating part of the acoustic noise emission is usually caused by the aerodynamic noise from the rotor blades. Adverse effects on the overall sound power level can espe‐ cially be caused by an unfavourable design of blade tips. Another noise source is me‐ chanical noise caused by the gear box, the generator, different aggregates or the invert‐ er. In general, different noise sources can be identified by a detailed analysis of noise spectra (i.e. frequency analysis). This way, valuable indications can be provided to wind turbine suppliers or owners, on how to reduce the noise emission and how to remedy unwanted noise characteristics. WindGuard staff members look back on many years of experience gained from hundreds of commercial noise measurements and, also, various international research projects on aerodynamic noise reduction, optimisation of meas‐ urement procedures and outdoor noise propagation.

After a wind farm has been commissioned, verification of the acoustic noise emission may be requested by local authorities – sometimes at regular intervals throughout the operating period of wind farms, in order to ensure observation of the (legal) noise limits. Also, noise verification measurements are offered by Deutsche WindGuard, utilising measurement techniques specifically developed for outdoor measurements under windy conditions.
