摘    要: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。

关 键 词:永磁同步发电机  全功率变流器  低电压穿越  无功补偿

Abstract:The control strategy for high speed wind turbine with permanent magnet synchronous generator(H-PMSG) is investigated to improve its capacity 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 is established in the software Matlab/Simulink.It has simulated two operation conditions of generator and converter when grid voltage dip by 30%(0.6 seconds),60%(2 seconds).The simulation shows that H-PMSG power track well.It could provide reactive power supporting when the grid voltages dip.The H-PMSG has a strong low voltage ride-through capability.
Keywords:permanent magnetic synchronous generator  full power converter  low voltage ride-through  reactive compensation
