说明：  介绍了无刷双馈异步风力发电机的结构及其发电调速原理。从无刷双馈电机的基 本方程出发，通过坐标变换，建立了无刷双馈电机在转子旋转坐标系下的d-q 模型，并进行了Matlab 建模和仿真。
(Introduced a brushless doubly-fed induction wind turbine structure and the principle of generating speed. BDFM from the basic equations, coordinate transformation, the establishment of a BDFM rotor rotating coordinate system in the dq model, and the Matlab modeling and simulation.)
