摘要
我国电力系统容量的持续扩大,使得其对继电保护装置动作正确率的要求不断提升。继电保护作为电力系统不可或缺的组成部分,是电力设备安全平稳运行的保障。然而在电力系统的实际运行过程中,常存在继电保护二次电压切换问题,这极大地影响了电力系统的正常运行。文中分析了二次电压切换回路中存在的问题,并针对异常原因提出了有效的解决措施。
Capacity of China's electric power system continues to expand,which imposes higher demands on correct op-eration of relay protection devices.Relay protection as an integral part of power system,guarantees safe and stable opera-tion of electrical equipment.However,in actual operation of the power system,secondary voltage switching in relay pro-tection often occurs,which greatly affects normal operation of the power system.Problems in the secondary voltage switc-hing circuit are analyzed in this article and effective measures to solve them are proposed.
