Analysis of measured flickers contributed by a commercial wind power generation system in Taiwan

This paper presents the measured results of flickers generated by a commercial wind power generation system (WPGS) in Taiwan. The studied WPGS consisting of four identical 660 kW wind-turbine induction generators (WTIGs) is connected to an 11.4 kV bus inside a large petroleum-chemical industrial mill located at the middle coast of Taiwan. The field measured flickers contributed by four WTIGs and a single WTIG are analyzed using a probabilistic approach since the measured quantities are random in nature. According to the measured flicker results, the generated voltage flickers of -V10 contributed by four WTIGs are evidently less than the flicker limitation of Taiwan Power Company (TPC) of Taiwan.
