| 摘 要： | 论文通过对CRH380B型高速动车组过分相区过程的理论进行分析,得出了由于牵引变流器中问直流环节电源变化对CRH380B型动车组辅助供电系统的不利影响,主要表现在电压的大范围波动。为防止电压大范围波动不影响辅助系统的供电质量,保证辅助变流器交流输出电压频率的稳定,应用Matlab7.0/Simulink进行了系统的建模与仿真分析,仿真结果表明所设计的双闭环控制策略能快速、准确地调整辅助供电系统的电压波动,确保列车过分相时辅助供电系统输出电压幅值、频率恒定。

| Abstract: | The article analysis the process of CRH380B EMU crossing the sub-phase region, and concludes that the variation of the DC-link have an adverse effect on CRH380B EMU ＇ s auxiliary power supply system, which mainly appear in a wide range of voltage fluctuations. In order to prevent a wide range of voltage fluctuations do not affect the quality of the power which the auxiliary system supply, and guarantee auxiliary converter output voltage frequency stability. The article builds model and simulates with Matlab7.0/Simulink, the simulation result shows that the double-loop control strategy which is designed can adjust the auxiliary power system voltage fluctuation quickly and accurately, ensure that the auxiliary power supply system output voltage and frequency stably. |
