摘要
针对220KV新民变电站1号变压器保护动作的原因,利用故障录波装置打印的事故故障正弦波型对保护装置动作情况进行理论分析,为有效保证电力系统安全稳定运行提供参考.
The operation situation of protection device was analyzed based on the No.1 transformer＇s relay protective action of 220kv substation in xinmin,using fault sine wave printed by the device of fault recorder,which provided a reference for safe and stable operation of power system.
