高速动车组牵引供电系统对外射频建模仿真分析

External RF modeling and simulation analysis of high speed EMU traction power supply system

该研究的目的在于搭建一个高速动车组牵引变流器及其供电系统的模型,并通过仿真来验证其薄弱点。因此每个牵引系统中的基本组件都会被建模,包括接触网、接地回流、牵引变压器、牵引变流器等,其对外射频的仿真结果重点关注了列车在牵引供电网络中所处的位置和额定功率下的对外射频数值的峰值点。这些成果可以用于牵引供电系统的改进。

The purpose of this study is to build a high-speed EMU traction converter and its power supply system model, and through the simulation to verify its thin weaknesses. So each traction basic components in the system are modeling, including contact network, grounding, traction transformer, traction converter. Its external RF simulation results focus on the train’s position in the traction power sup-ply network and power rating of the peaks of the external RF value. These results can be used for improvement of the traction power supply system.
