摘要
介绍一起由线路故障引起220kV母线母差保护动作的特殊故障,结合保护、母差保护动作情况及故障录波图,分析推断了故障的发展过程及线路、母差保护动作的正确性。
A typical fault of line breakdown caused the operation of 220 kV bus p rotection. Combined with the action of the line protection, bus protection and t he wave-record chart, this paper analyses the development course of the breakdow n as well as the validity of the action of the line and the bus protection.
