摘　　要：对于采用双馈电机的变速恒频风力发电系统,多应用矢量变换方法和PI控制器进行控制,此控制方法依赖于电机参数。将模糊控制技术引入双馈风力发电控制系统。以提高系统的抗发电机参数扰动性。采用Matlab/Simulink建立了各单元模型并进行仿真。仿真结果表明:所设计模糊控制器在空载并网控制中具有很强的鲁棒性和适用性。The variable speed constant frequency（VSCF） wind-power system with doubly-fed induction generator is common controlled with vector transform method and PI controller which depends on the parameter of electric machine. The fuzzy control was used to control the doubly-fed wind-power system in order to improve the control affection in the dissertation. The simulation model is built by Matlab/Simulink to simulate. It comes to a conclusion that fuzzy-control had good robustness and applicability in the idle load grid-connection control.
