电气化铁路牵引供电对江门电网的影响及其应对措施

随着广珠铁路和广珠轻轨铁路江门支线建设的进展,电气化铁路和牵引供电等新的用户就进入江门供电局的服务范围,单相整流负载的电气化铁路对电网的影响具有其特殊性。本文从理论分析、仿真实验及工程经验三个方面探讨了电气化铁路产生的谐波、无功功率和负序电流,并阐述了其将对江门电网的影响,提出采用单相注入式混合电力滤波器与静止无功补偿器的复合补偿方案,以提高电网的稳定性和安全性。

The Effect of Electrified Railway Traction Power Supply on Jiangmen Grid and its Response

With the construction progress of Jiangmen extension of the Guangzhou-Zhuhai Railway and Guangzhou-Zhuhai light rail,new electric users such as electrified rail and traction power supply will enter into the scope of services of Jiangmen Power Supply Bureau,single-phase rectifier load on the grid of electrified railway has its speciality.This article has explored harmonic,reactive power and negative sequence current brought by electric railway from the theoretical analysis,simulation and engineering experien...
