The dynamic reactive power compensation equipment in Jiuquan Wind Power Base of above 10 GW consists of three different types of compensation devices,including:static var generator(SVG),thyristor controlled compensator(TCR)and magnetically controlled reactor(MCR).The lack of experimental verif ication of performance is not conducive to voltage/var management or full utilization of device capacities.In order to solve the above problems,the compensation device performance test was performed.The test items and procedures were selected based on related national standards with the consideration for different grid structures and wind farm operation modes.The testing contents included dynamic regulating range, active power loss,dynamic response time,and harmonic voltage level.Three types of compensation devices installed in different wind farms,namely SVG,TCR and MCR,were chosen and tested.The performances were compared and analyzed according to the field test results.
