动车组牵引传动系统HIL仿真平台被控对象建模研究

Research on Controlled Objects Modeling of EMU Traction Drive System HIL Simulation Platform

讨论了动车组牵引传动系统HIL仿真平台被控对象正常建模和故障建模,包括牵引变压器、四象限整流器、中间直流回路、逆变器和牵引电机等,故障模型是在正常模型基础上完成的,两者均以状态方程形式实现。

This paper establishes the normal models and fault models of the controlled objects of EMU traction drive system HIL simula- tion platform, mainly including traction transformer, 4-quadrant rectifier, intermediate DC circuit, inverter, traction motor and so on. The fault models are established on the basis of normal models. They are both described by state equations.
