摘要
为了提高变电站母线差动保护运行的可靠性,防止母线差动保护不正确动作的发生,本文通过一例220 kV母线差动保护异常启动原因的探究,找到了CSC150母线差动保护装置软硬件方面存在的隐蔽性缺陷,为巡检母线差动保护设备提供借鉴。
To improve the reliability of the substation bus-bar differential protection operation, and prevent the occurrence of bus-bar differential protection misoperation, the CSC150 bus-bar differential protection device concealed defects existing in the hardware and software aspects is found, from the cause analysis of a 220 kV bus-bar differential protection abnormal start-up, which provides a reference for checking bus-bar differential protection device.
