Influence Study on Electric Vehicle-traction Network System Considering Pantograph Arcing

Abstract

This article analyzes the influence of pantograph arcing phenomenon on the electrical quantity which is related equipment of traction power supply system. The Mayer arc model was improved by taking into account arc dissipation power, arc diameter, transverse blowing arc and so on, based on this, modeling was performed, the traction power supply system such as AT doublewire traction network model and CRH3 EMU load model was described mathematically later on, and simulation analysis was ultimately achieved using MATLAB/Simulink software. The study results show that the pantograph arcing phenomenon causes the harmonic components that are the voltage and current of the traction network to increase, at the same time, making the performance indexes of the DC-side voltage of the CRH3 EMU rectifier to change.
