Power quality performance analysis of a wind turbine is necessary to properly characterize the turbine before proceeding to grid integration. The analysis requires following strict guidelines stated in available international standards. This paper discusses the available international standards for power quality analysis along with the procedures used for different parameter calculations. The principal object of the paper is to demonstrate the difference between non overlapping block mode and sliding mode iteration methods during parameter calculations. Results indicate that the non overlapping block mode method is a faster iteration process with a similar accuracy to the sliding mode method during wind turbine characterization. The paper showed power quality parameters calculated using the non overlapping block mode method and also discusses the effect of a high number of samples on the overall analysis result. High resolution recorded data from a grid connected wind turbine in West Texas is used for the analysis.
