安钢220kV变电站继电保护改造中存在的问题及解决措施

Problems and Solutions of 220 kV Substation Relay Protection Modification in Angang

针对范家庄220 k V变电站继电保护改造中存在的保护装置属淘汰产品,变电站原有设备不符合220 k V变电站标准配置等问题进行了论证,提出了直流负荷转接、110 k V PT改造等措施,为其他老旧变电站继电保护改造提供参考。

Some problems such as backward protection device and original equipment not accord with the standard exist in220 k V substation relay protection of Fanjiazhuang. The paper analyses these problems, puts forwards corresponding measures from direct current load and 110 k V PT. It can provide reference for other substations.
