摘　　要：回流系统是电气化铁路牵引网的重要组成部分。本文从耦合多平行导线电路计算原理出发,结合工程实际对单线直供牵引网回流系统的电气特性进行了仿真计算,对牵引变电所处有无接地电阻2种工况下的电流分配和电压分布结果进行了对比分析,并得出结论。The return current system is an important part of the traction network of electrified railway. The paper, starting from the calculation principles of coupled multiple parallel conductors, in connection to the actual engineering practice, simulates and calculates the electric characteristics of return current system for single track direct power supply traction network, compares and analyzes the current distribution and voltage distribution under two types of with/without earthing resistance in traction substation, and the conclusions are obtained accordingly.
