500kV线路串补旁路隔离开关与线路高抗隔离开关的操作顺序分析

随着超高压电网的快速建设,500kV线路串补设备及线路高压并联电抗器的应用越加广泛,变电站设备的增多导致了操作的复杂性。对同一条线路上的串补装置旁路隔离开关与线路高抗隔离开关的操作顺序进行了系统的分析,可从根本上避免误操作的发生,为电网的安全运行提供可靠保障。

Analyze on the Operation Order of Series-compensation Bypath Disconnector and High-resistance Disconnector on 500 kV Lines

Along with the high speed construction of the EHV grid,the application of series-compensation equipment and high voltage shunt reactor on 500 kV lines has become more and more extensive.The increasing of the substation equipment led to the complexity of the operation.This paper makes the systematic analysis on the operation order of the series-compensation bypath disconnector and high-resistance disconnector on 500 kV Lines for avoiding the incorrect operation fundamentally and providing the reliable guarantee for the safe operation of the grid.
