摘　　要：在传统风力发电的基础上,以作为风力发电机用的无刷双馈电机为主要研究对象,进行了深入的研究,研究了无刷双馈电机的转子侧和网侧PWM变换器的控制策略,建立转子侧和网侧PWM变换器控制策略的结构模型,把功率绕组和控制绕组分别建立在各自的同步坐标系下,分别进行磁场定向和电压定向矢量控制,从而简化了数学模型,获得了适合的控制策略。最后采用Matlab/Simulink仿真软件建立相应的控制系统仿真模型,模拟三种情景,进行仿真实验,分析实验结果。In this paper, based on the traditional wind power generation, the variable-speed constant-frequency generation technology is mainly research, a comprehensive research on the BDFM with cage rotor used in the variable-speed constant-frequency wind power generation. This paper has analyzed the stator flux oriented vector control strategy and mathematic model of the BDFM as vscf wind power generator. Design the control system of Wind power generation with BDFM and the experiment of Variable-speed constant-frequency which BDFM is used in Wind power generation is finished.
