摘　　要：在一台电励磁双凸极发电机定子上设置两套3相电枢绕组实现双通道发电,通过调节励磁电流大小使两发电通道输出相应的额定电压,并联向负载供电。用等效磁路模型对双绕组电机的电感特性进行了理论研究,并用有限元方法对其电磁特性进行仿真计算,仿真结果与分析相一致;同时介绍了双余度发电系统的硬件构成,并实验验证了系统具有很好的稳态、动态特性和可靠性。A doubly salient electro-magnetic generator （DSEG） employs two independent channels consisting of two groups three phase windings. The two channels provide power to the same load and output voltage reach the demand through adjusting the excitation current. The paper analyzed inductance characteristics of the double winding DSEG through equivalent magnetic circuit modeling, the static characteristic is obtained using finite element method and simulation results are given to prove the analysis conclusion. In addition, system hardware and experiment results for two redundancy DSEG system are presented. Experiment results show that the system have excellent static and dynamic characteristic and high reliability.
