摘要
简单探讨了广东电网继电保护日常运行中比较常遇到的几个问题,包括纵联保护的命名、双母接线变电站电压互感器检修时母线电流差动保护的处理方法、220 kV母线保护和线路主保护退出时的处理、有关旁路代路要注意的几个问题、线路单电源侧充电时的处理,并对以上问题的处理方法进行了原理性的解释。
Several common problems in daily running of relay protection in Guangdong power system are briefly discussed, which include the naming of pilot protection, handling of busbar current different protection during the maintenance of a potential transformer in a double-bus scheme substation, what to do when 220 kV bus protection and line main protection are out, points for attention as to the use of by-pass circuit, and line, etc. The solutions for the above problems are explained treatment during charging on single supply side of a 220 kV theoretically as well.
