摘　　要：多相整流发电机因其直流供电品质高、可靠性高,在船舶电力推进中得到了越来越多的应用,整流发电机的并联运行对于提高船舶电力系统的容量和安全性具有重要意义。推导了十二相同步发电机的数学模型,在MATLAB/Simulink中建立了两台带不控整流的十二相同步发电机并联运行的仿真模型。探讨了两台并联运行发电机间功率分配的控制策略,设计了电压—电流下垂特性曲线和曲线截距的自动补偿,并将其应用到励磁控制系统中。通过仿真实验,验证了该控制系统的有效性。Thanks to high DC power quality and reliability, multiphase generators are increasingly used on ship electric propulsion system, and the parallel operation of generator-rectifier systems is very important for the onboard electrical system in both capacity and safety. The paper describes mathematical equations of twelve-phase synchronous generators, models two parallel generator-uncontrollable rectifier systems in MATLAB/Simulink, discusses the control strategy of active power distribution, designs the voltage-current droop characteristic and automatic intercept compensation, and finally applies the strategy to Excitation Regulator. Simulation results demonstrate the validity of the control system.
