秦皇岛地区两座220kV变电站的电铁谐波治理

就如何对 2 2 0 k V变电站的电铁谐波进行治理及具体实施进行了介绍。这次谐波治理方案的主要特点是在电力系统的 2 2 0 k V变电站内进行滤波。一台 2 2 0 k V主变的低压侧安装了 4组滤波电容器组 ,分别对 3、5、7、1 1及以上谐波进行了治理。滤波电容器组投运后 ,经华北电力谐波管理站测试 ,母线电压畸变率和谐波用户注入电力系统的谐波电流均达到了国标的要求 ,主变力率得到了提高 ,取得了显著的经济效益和社会效益

Control of Electrification Railroad Harmonics of 220kV Substations in Qinhuangdao Area

This article describes how to control electrification railroad harmonics on 220kV substations. That is to put four sets of capacitor filters on the low voltage side of the 220kV transformer to control the third, fifth, seventh, eleventh, and even higher order harmonics separately. After the capacitor filters were put into operation, harmonics were measured by the Harmonics Administrative Station of Huabei Electric Company, showing that total harmonic distortion for voltage and harmonic current flowing into the electric power system from the consumer meet the national standard.
