In this paper, the voltage fluctuation issue of the train body caused by the discharge phenomenon between the wheel-set and rail when the CRH2 electric multiple units (EMUs) runs through the rail insulation section is studied. Firstly, the working grounding and protection grounding systems of CRH2 EMUs are introduced, and then, we established the equivalent model of CRH2 EMUs grounding system and confirmed its parameters. Meanwhile, insulating section discharge model is also established. Secondly, the simulation results show all the car body voltages as wheel-rail discharge phenomenon occurs, and we analyze CRH2 EMUs grounding system structure itself. Finally, we come to the conclusion that the change of value of the grounding resistor shall make CRH2 EMUs train body electric potential difference at the time of isolated rail joint discharge phenomenon lower than before.
