摘　　要：针对新型的电励磁五相双凸极发电机的结构特点和工作原理,在二维磁场有限元非线性计算分析的基础上,对外接单相桥整流发电电路的发电机发生二极管短路故障时的容错特性进行了理论分析和仿真验证。分析表明:外接单相整流桥的电励磁五相双凸极发电机在发生二极管短路故障时空载运行情况与正常时基本相同,不会由于短路相的影响发生系统崩溃,这与其他发电方式有显著不同;负载运行时输出电压有所下降,但仍有较好的容错性能,可通过提高励磁电流维持正常时的输出功率。In accordance with structural features and working principles of the novel five phase doubly salient electromagnetic generator,using two-dimensional finite element electromagnetic field analysis method,the fault tolerant characteristic is analyzed,under the condition that the shorted diode circuit faults of the generator consisted of external single phase bridge happened.The research shows that the fault no-load characteristic is the same as the normal.The fault phase has little effect on the whole system.On the load situation,the output voltage is low as the normal,which has cetain fault tolerant performance.Generally speaking,the output power stands by improving field current.
