摘　　要：无刷双馈电机(简称 BDFM)是近年发展起来的新型交流电机,它在大型电力驱动和风力发电领域具有很好的应用前景。在详细分析无刷双馈电机的电磁关系和稳态等效电路基础上,利用相量图对 BDFM 的能量可逆过程进行了研究,并对 BDFM 在各种速度和电动、发电状态下的功率平衡与功率流程关系进行了详细分析,为 BDFM 的控制与应用奠定了理论基础。The Brushless Doubly-Fed Machine （BDFM） is a novel AC machine developed in recent years, and it has a good application prospect in the field of large-scale electrical drive and wind power generation. Based on the detailed analysis of electromagnetic relation and steady-state equivalent circuit, the energy reversible process of BDFM was studied by means of vector graph. And aiming at the BDFM of different speed and in motor or generator state, the relationship of power balance and power flow was analyzed in detail, which establishes the theoretical foundation for the control and application of BDFM.
