摘　　要：在500 kV系统中装设串联电抗器可以在不改变电网结构、不影响潮流分布和电网稳定性的条件下有效地限制系统短路电流水平,从而确保断路器的正常运行。论述了上海500 kV电网安装高压串联电抗器的必要性,结合500 kV泗泾—黄渡线路串抗工程,对相关的过电压课题进行了分析,并提出了相应的建议。To install series reactors in 500 kV systems can effectively limit the short-current level of the system without having to change the grid structure and affecting the flow distribution and grid stability, thus can ensure normal operation of circuit breakers. The necessity of installing high voltage series reactors in Shanghai 500 kV grids is illuminated, and consequent over-vohage problem is analyzed for the series reactor project for 500 kV Sijing-to-Huangdu line. Relevant suggestions are proposed.
