摘要
结合动车组辅助供电系统的特性分析了去分相的前提条件,以标准动车组为例,利用Matlab搭建仿真模型,分析了电力电子自动过分相装置中间电压的波动情况,检验了利用电力电子开关自动过分相的适应性。
With connection to the characteristics of the auxiliary power supply system of EMU,the paper analyzes the preconditions for cancellation of the neutral section,taking the standardized EMU as an example,by establishing of simulation model with Matlab,analyzes the fluctuation of intermediate voltage of automatic electric and electronic switch for passing of neutral section,verifies the practicability of application of electric and electronic switch for automatic passing of neutral section.
