摘　　要：以直驱风力发电系统为研究对象,选用背靠背双PWM的拓扑结构,针对永磁同步风力发电机机侧的控制策略进行分析。在建立永磁同步风力发电机数学模型的基础上,基于isd=0的转子磁场定向控制,设计了电流内环转速外环的双闭环控制器,并对控制原理在Matlab/Simulink上进行仿真实验,验证了该控制策略的正确性。The subject of this paper is direct drive wind power generator. It use the topological structure of back-to- back PWM converter, and mainly analyze the control strategy in generator-side of permanent magnet direct drive wind power generator. Then build the mathematical model of PMSG. Based on rotor filed oriented control, Double-closed loop control of the inner-current and the outer-voltage is designed. And then build the simulation model in Matlab/ Simulink according to the principle of control strategy. The experiment results verify the correctness of control strategy.
