电力机车列车供电系统接地研究

Research on Grounding Problems of Power Supply System for Electric Locomotive

详细介绍了列车供电系统多种接地方法,并给出其相应的工作原理图,利用Matlab建立电力机车列车供电系统模型,对每一种接地情况作了闭环仿真分析,通过多方面的仔细研究和论证,并结合现场的高压试验验证,找出了最佳的接地判断解决方案,为列车供电系统的接地判断提供了必要的依据。

This paper Introduced a variety of train power system grounding method, and gives the corresponding working principle diagram, use Matlab to establish electric locomotive train power system model, for each ground conditions were closed loop simulation analysis, through careful study and demonstration in many aspects, and the combination of high voltage test verification field, find out the best the ground judge solution for power supply system of train ground judge provide necessary basis.
