摘　　要：建立了六相整流永磁同步发电机系统的多回路—有限元结合的数学模型。该模型不仅可以考虑磁路饱和及永磁体工作点的变化的影响,也可准确反映整流桥的各种工作状态及换流过程。利用该数学模型对一台六相永磁样机系统的定子绕组和直流负载侧电压、电流等电气量进行仿真计算,可分析六相可控整流永磁同步发电机系统的运行性能。A mathematical model was established that combines the multi-loop theory and the finite element （FE） method for 6-phase permanent-magnet（PM） synchronous generator with rectifier load system. This model not only takes consideration about the influence of armature reaction on PM working point, but also accurately reflects all kinds of working state and commutation of the rectifier bridge. Based on the mathematical model, the voltages and currents of the stator windings and DC load of a 6-phase PM prototype system were simulated digitally. The simulation results indicates that this model can be used to analyze the operating performance of the system.
