摘　　要：基于双PWM型永磁直驱风电系统,对机侧和网侧的变流器控制策略进行了详细分析,提出直驱永磁风电系统机侧和网侧采用PWM控制方式,可以有效地稳定直流电压,实现风能的最大捕获,以及侧有功功率与无功功率的解耦,从而实现全功率并网。利用Matlab/Simulink搭建了仿真平台,并给出了仿真结果,证明了该控制系统的正确性与可行性。Based on the back-to-back PWM converter,the control theory of motor-side and grid-side of the permanent magnet direct-driven wind power generation system was detailed analyzed.The PWM control strategy in motor-side and grid-side was presented,which can stabilize the DC voltage of the system.The system was able to obtain the maximum wind power.The active power and reactive power can be decoupled,realizing unity power factor operation.Matlab/ Simulink model was set up and the system simulation verify the validity and the feasibility.
