摘　　要：针对新能源场站低电压穿越问题,设计了人工短路实验方案,在110 k V香沙Ⅰ线香山变电站线路出线侧设置单瞬故障,并给目标风电场以不同的无功补偿,找出无功功率对风电场低电压穿越能力的影响,试验结果表明:在单瞬故障时风电场具备低电压穿越能力,无功补偿对提高低电压穿越具有强效力。Aiming at the problem of low voltage ride- through in new energy station, designed artificial short-circuit test schemes: to set up single instantaneous faults in the line outlet side in Xiangshan Substation, 110 kV Xiangsha No.1 transmission line, make objective wind farm different reactive power compensation, find out the influence of reactive power on the low voltage ride-through capability in the wind farm. The test results show that the wind farm possesses the low voltage ridethrough capability in the time of single instantaneous faults. The reactive power compensation has strong effect on promoting low voltage ride-through capability.
