摘要
对根据IEC 61400-21标准进行测试的四款风电机组,即750 kW定桨失速型机组、2 MW变速恒频全馈机组、2.5 MW变速恒频双馈机组和运达(WD77-1500 A/1500 kW)变速恒频双馈机组的电能质量测试和评估报告进行了分析,通过比较风电机组闪变的测量值、谐波电流值,可对各种风电机组在不同方面的性能有一定的了解。
Measurement and assessment of power quality of four wind generation systems which are 750 kW stall-regulated WTGS,2 MW variable speed constant frequency WTGS,5 MW doubly-fed variable speed constant frequency WTGS and Yunda（WD77-1500A/1500 kW） doubly-fed variable speed constant frequency WTGS are made.A variety of properies of wind turbine are known by comparing the measured value of flicker with harmonic current value.
