摘要
就220kVMD线故障跳闸,A相高频保护M站侧保护动作,而D站侧A相高频保护屏跳闸灯亮,却没有保护报文;两侧B相高频保护都仅是起动的情况,依据保护报文、录波图及保护原理对保护跳闸行为进行分析,确定故障类型为发展性故障,并且保护动作行为正确。分析过程具有一定的借鉴价值。
In this paper, according to the 220 kV MD line fault tripping, A-phase high frequency protection of M substation protection action, and D substation side of the A-phase high-frequency protection screen trip lights, but no protection at text on both sides of the B-phase high frequency protection are just starting. Based on the paper reported on the situation, the protection of recorded waveform of tripping behavior, and the principle of protection, it analyses tripping behavior to determine fault type for the development of fault, and the protection of the right moves. Analysis of the process has some reference value.
