官地水电站500kV GIS设备3/2接线出线保护配置方案

Outlet Protection Configuration Scheme of Guandi Hydropower Station 500kV GIS Equipment 3 /2 Connection

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。

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.
