摘　　要：短路故障瞬态特性的研究对永磁风力发电机的安全稳定运行具有重要意义。本文以带阻尼绕组的凸极式永磁风力发电机(Salient Pole Permanent Magnet Wind Generator, SPPMWG)为研究对象,对发电机短路时的瞬态特性进行研究。首先设计了一种带阻尼绕组的SPPMWG磁极结构,利用Maxwell软件建立SPPMWG的有限元模型,然后联合Simplorer建立其短路故障下的场路耦合计算模型,最后对不同短路故障进行仿真计算,对电机瞬态参数及阻尼绕组对短路特性的影响展开了分析。结果表明,阻尼绕组对抑制SPPMWG的短路电流及永磁体退磁起到了重要作用。The research on transient characteristics of short circuit fault is of great significance to the secure and stable operation of permanent magnet wind generator. In this paper, the transient characteristics of salient pole permanent magnet wind generator(SPPMWG) are studied. Firstly, the magnetic pole structure of SPPMWG with damping winding is designed, and the finite element model of SPPMWG is established by using Maxwell software. Then the field circuit coupling calculation model under short circuit fault is established by combining with Simplorer. Finally, different short circuit faults are simulated, and the influence of transient parameters and damping winding on short circuit characteristics are analyzed. The results show that damping winding plays an important role in suppressing SPPMWG short circuit current and demagnetizing permanent magnet.
