Abstract

Wind energy is becoming the mainstream source of power generation worldwide. However, as the wind speed variate, it results in power fluctuations, and power converters adversely affect the power quality of grid-connected wind turbines (WT). The power quality measurement procedure is defined in the standard IEC-61400-21. The updated standard IEC-61400-21-1 provides a uniform methodology, which will ensure the accuracy of the testing and assessment, i.e., voltage quality (emissions of flicker and harmonics). The flicker emission produced by the turbine due to rapid changes in wind speed results in fluctuating power, which can lead to voltage fluctuations at the point-of-common-coupling (PCC). The IEC-61000-4-15 standard describes the measurement specification of the flicker meter. The accuracy of the measuring methods is an essential part of the assessment of power quality in the grid-connected WT. This paper introduces the innovative procedure of flicker measurement model of grid-connected WT. Therefore, the paper deals with the verification test of the measurement procedure for the flicker, and the results demonstrated through the simulation according to the measurement and assessment standard IEC-61400-21-1.
