摘　　要：介绍了变速恒频双馈感应风力发电机运行的基本原理,分析了风力机功率特性和风能追踪的控制策略,对双馈感应发电机转子侧的变换器控制系统进行了建模与仿真。通过控制发电机输出有功功率来调节电磁转矩和转速,将定子磁链定向的矢量变换控制技术应用在对双馈型异步发电机转子侧变换器的控制上,获得了发电机有功功率和无功功率的解耦控制,为追踪与捕获最大风能创造了条件。电网侧的变换器使用电网电压定向的矢量控制技术来控制直流母线电压的恒定,调整了电网侧的功率因数。The paper introduces the basic principles of variable speed constant frequency double-fed wind power generator,and analyzes the wind turbine power characteristics and the wind power tracking control strategy . Then the modeling system and simulation of doubly fed induction generator （DFIG）rotor side converter control system is built. The generator＆#39;s output active power is controlled to regulate the electromagnetic torque and speed. The stator field oriented vector control technology is used in the control of double-fed induction generator rotor side converter to achieve active and reactive power decoupling control,in order to create the conditions for tracking and capturing maximum wind energy. The converter at the grid side uses the grid voltage oriented vector control technology to con-trol the constancy of the DC bus voltage and adjust the power factor of network side.
