Discuss on the Impact of High-speed Electrified Railway on Hubei Power Grid

Qin Yue-jin

Abstract

As a special user in power system,high-speed electrified railway possesses the features of nonlinearity,asymmetry,fluctuation and large power.This paper briefly describes the Wuhan-Guangzhou high-speed electrified railway,and takes Quankou traction station power quality test results for example,the load characteristics of electrified railway,the impacts of negative sequence and harmonics generated from electrified railway to power grid are analyzed.Then some controlling measures are proposed to ease the impact on Hubei power grid.
