摘　　要：针对现存电力电容器组的不足,提出了1种基于磁控电抗器和FC的动态无功补偿装置,配合撬棒(crowbar)保护电路实现双馈风电机组的低电压穿越。在Matlab/Simulink中构建了基于控制策略的双馈风电机组模型,通过不同控制策略运行结果的仿真对比,验证了所提出的控制策略的有效性。For the insufficiency of existing power capacity bank, the dynamic reactive power compensation device based on a kind of magnetically controlled reactor and FC is proposed,together with crowbar protection circuit to achieve low voltage ride-through of DFIG. The DFIG model based on the control strategy is built in the Matlab/Simulink,and the efficiency the proposed control strategy is proposed through simulation comparison of different control strategy operation result.
