摘要

: 首先介绍了某地铁牵引供电系统的结构、特点及牵引供电方式，对电力机车、牵引网、电缆构成的牵引供电系统进行详细地仿真建模，分析计算了各种运行工况下牵引供电系统的谐波电流水平。最后针对不同系统阻抗下 110 kV 电缆可能引发谐波电流放大的风险进行了评估。

Abstract

Firstly，the structure，characteristics and traction power supply mode of a traction power supply system are introduced，and then the detailed simulation modeling of the traction power supply system is carries out which is composed of electric locomotive，traction network and cable． The injection of harmonic current component is analyzed under different operating conditions． Finally，the risk of harmonic current amplification by the 110 kV cables is assessed under different system impedance．
