研究高速永磁同步风电机组的控制策略，提高其低电压穿越能力。在matlab／simulink环境下构建了背靠背双PWM变流器并网的高速永磁同步风电机组仿真模型。模拟了发电机和变流器在电网电压跌落30％（0．6s），60％（2s）时的运行情况。仿真结果表明：高速永磁同步发电机机组功率跟踪良好，在电网电压跌落时对电网提供无功支持，具有较强的低电压穿越能力。%The control strategy for high speed wind turbine with permanent magnet synchronous generator （H-PMSG） was investigated to enhance its capability of low voltage ride through（LVRT）.A H-PMSG model comprising of a host AC power grid with two back-to-back PWM voltage source converters was established in the software matlab/simulink. It has simulated two operation conditions generator and converter when grid voltage dip by 30%（0.6 seconds） ,60%（2 seconds）.The simulation indicated that H-PMSG power tracked well. It could provide reactive power support when the grid voltage dip. The H-PMSG had a strong low-voltage penetration capability.
