官地水电站500 kV GIS设备3／2接线出线保护配置方案

摘要

The paper compares two possible outlet protection configuration schemes for the 3/2 connection of Guandi Hydropower Station 500kV GIS equipment, and introduces the final determination of scheme . The paper also proposes the protection configuration scheme which both can fast act to clear fault , and does not start this side of the circuit breaker reclosing for the GIS equipment outlet T zone fault .%文章对官地水电站500kV GIS设备3/2接线方式，两种可能的出线保护配置方案进行了优劣比较，对方案的最终确定做了介绍，并进一步提出了在GIS设备出线T区内故障时既能快速动作切除故障，又不启动本侧断路器重合闸的保护配置探讨方案。
