摘　　要：基于无刷双馈风力发电机(BDFM)特殊的结构特点和工作原理,从转子参考轴d-q模型出发,构建BDFM在同步参考系下的数学模型。通过对控制绕组进行交流励磁,对变速恒频无刷双馈发电机的有功和无功解耦控制,最终实现最大风能的有效捕捉。Based on the special structural features and operation principle of brushless doubly - fed machine （ BDFM ）, the mathematical model for BDFM is built up under the synchronous coordinates according to the point of rotor speed d - q model. By means of control winding make the AC excitation, the new strategy realizes the decoupling control of active and reactive power of VSCF （variable speed constant frequency） generator, eventually the generating operation mode with high efficiency that can capture maximal wind energy is come true.
