摘　　要：无刷双馈发电机是一种新型的双定子绕组感应发电机,它的两套绕组(功率绕组和控制绕组)都被固定在定子上。本文提出了一种新的T型稳态模型。相对于常规Π型稳态模型和简化的内核稳态模型,这种新的T型稳态模型更适合于独立无刷双馈发电机的性能分析。基于所提出的T型稳态模型,对无刷双馈发电机的功率流和控制绕组电流特性进行了理论分析,并且通过实验验证了分析结果的正确性。该分析结果表明独立无刷双馈发电机在超同步速运行时有更优的性能,并且为进一步提高无刷双馈发电机独立发电系统的动态性能奠定了基础。The brushless doubly-fed generator （BDFG） is a dual stator winding induction generator, both windings （power winding, PW, and control winding, CW） are housed in the stator. A new T-type steady- state model of BDFG was proposed, which was more suitable for the performance analysis of stand-alone BDFIG than the conventional H-type and the simplified inner core steady-state model. The characteristics of the power flow and CW current was analyzed based on the T-type steady-state model. The analysis results were verified by experiments. The results of the performance analysis have indicated that the stand-alone BDFG has more excellent performance in super-synchronous speed and can contribute to improve dynamic performance of the stand-alone BDFG.
