摘要
介绍了列车牵引系统主电路原理,通过在半实物仿真平台上搭建列车牵引系统模型,模拟列车实际运行工况,某一时刻四象限IGBT脉冲信号丢失,观测中间直流母线电压、四象限输入电流、逆变器输出电流等关键变量故障波形,分析该故障工况对列车牵引系统造成的影响。
This paper introduce the principle of main circuit of train traction system.The model of train traction system is built on the semi-physical simulation platform to simulate the actual operating conditions of the train.At a certain time,the PMCF IGBT pulse signal is lost,the fault waveforms of key variables such as DC bus voltage、pmcf input current,INV output current are observed,and the influence of the fault condition on the train traction system is analyzed in this paper.
