电动车组谐波评判方式简析

Brief Analysis of Harmonic Evaluation Methods for EMU

电气化铁路牵引供电系统谐波及其评判标准一直是电力和铁路部门关注的问题。电动车组及电力机车为主要谐波源,对其评判仍没有明确的标准进行规定。本文对国内外供电系统的谐波评判标准和方法进行了简单介绍,同时结合动车组实测网侧谐波,对电动车组网侧谐波评判方式提出了相关建议。

The harmonics of the electrified railway power supply system has been a big issue of concern by electricity and railway depart- ments. As the main harmonic source, there is still no definite standard requirements for the harmonic evaluation criteria of EMU and e- lectric locomotive. In this paper, harmonic evaluation criteria and methods for power supply system is made a brief introduction. Combined with the measured EMU harmonics, some relevant proposals is put forward for the harmonic evaluation methods.
