摘　　要：风力发电机组大多采用异步发电机,风力异步发电机并网发电时,会产生电压波动等一系列电能质量问题。通过论述异步风力发电机和级联STATCOM的数学模型,提出在风电场出口并联级联STATCOM的方法来解决风电场并网电压稳定性等问题。仿真结果表明,该方法可以有效并迅速地解决风电场并网电压稳定问题,提高风电场低电压穿越能力以及故障恢复能力。Wind turbines mostly use asynchronous generator and would produce a series of power quality problems such as voltage fluctuations at grid-connected generation. Through the analysis of mathematical model of the wind asynchronous generator and cascade STATCOM, puts forward the parallel cascade STATCOM in the export of wind farm to solve the problem of voltage stability of grid-connected generation. Simulation results show that the method effectively and quickly solves the problem of grid-connected voltage stability and improves the low voltage ride-through capability and fault recovery capability.
