摘　　要：针对新型内燃动车组牵引变流器和辅助变流器共用一套内燃动力包的需求,为保证发电机输出电压同时满足牵引变流器和辅助变流器在各种复杂工况下稳定运行,开发一种发电机励磁控制系统,并针对发电机特性和列车实际运行工况,设计了内燃动车组发电机励磁控制算法,经现场运行测试表明,该励磁控制系统运行稳定,在极端工况下发电机输出电压没有出现过压、欠压或振荡现象,完全满足内燃动车组运行需求。In view of the demand that the traction converter and auxiliary converter of the Diesel Multiple Unit(DMUs)share the power package,in order to ensure the output voltage of the generator can simultaneously meet the stable operation requirements of the traction converter and auxiliary converter under various complex conditions,a generator excitation control system is developed.According to the characteristics of the generator and the actual operating conditions of the train,the excitation control algorithm of the DMUs generator is designed,The excitation control system operates stably,and the output voltage of the generator does not appear overvoltage,undervoltage or oscillation under extreme conditions,which fully meets the operation requirements of the DMUs.
