摘要
为了减少电气化铁路对其沿线的通信系统造成的干扰 ,电牵引供电系统可以采用自耦变压器供电方式。本文分析了此系统中的机车驱动谐波污染情况 ,建立了 SS4型电力机车、牵引网及牵引变电所的模型 ,并通过 MATLAB仿真计算出在多机条件下电力机车。
Electrification railway will interfere with the communication system along the l ine.To decrease this kind of interference,the autotransformer power-supply mode can be adopted.In this article,we analyze the status of locomotive drive harmon ic pollution in the system,set up the models of SS4 electric locomotive,traction net and traction substation,and use MATLAB software to simulate and calculate t he harmonic currents and their content in the electric locomotive,traction net a nd traction substation.
