摘　　要：推导并分析了Y-△混合绕组的绕组系数及谐波幅值强度,并将之用于兆瓦级的双馈风力发电机中,通过有限元仿真分析了不同定转子槽型对谐波的影响,并与普通Y绕组进行对比,指出Y-△混合绕组能提高基波分量的绕组系数,同时对某些谐波能降低甚至消除。本文介绍的分析方法有助于风力发电机的电磁性能优化设计。The winding coefficient and harmonic magneto-motive forces （MMF＇s） of Y-△ mixed winding are presented, which is applied to MW-class doubly-fed wind power generator. The effect of slot type of mixed winding and normal winding are calculated by means of finite element method. The results show that the mixed winding can improve the base-frequency winding coefficient and reduce the harmonic winding coefficient. The method presented in this paper is useful for optimal design of wind power generator.
