摘　　要：文章通过对川西锦官梯级水电站送出通道现已存在的潮流N-1过载问题,以及随着电网发展即将面临的个别站点短路电流超标问题的分析,推荐在锦东—裕隆500 kV线路加装串联电抗器,实现同时解决上述两个问题的目的。In this paper,based on analysis about the problems evolution of the Jinping and Guandi cascade hydropower stations send out 500 kV transmission lines and stations or converter station,one problem is the current N-1 overload that is already faced in the existing power grid,another problem is the short-circuit current overshoot that will be faced with the development of the power grid in two years.In order to solve the above two problems,this paper recommend to installment series reactor in the Jinping Dong hydropower station to Yulong converter station 500 kV lines.

关 键 词：N-1过载 短路电流超标 串联电抗器
