摘要
电铁负荷作为两相供电整流干扰源会给电网带来严重的电能质量问题,影响供电质量和系统安全稳定运行。对220 kV莫合泉变电站的电能质量进行了现场测试和分析,发现电铁负荷对该变电站的谐波电流产生了严重影响,并给出了初步的改善建议。
As a two-phase interference rectifying power supply,electric railway load will bring serious power quality problems to the power grid,which will affect the quality of power supply and the stable operation of the power system.In this paper,the power quality of 220 kV Mohequan station is tested and analyzed.It is found that the electric railway load has a serious impact on the harmonic current of the station,and the preliminary improvement suggestions are given.
