摘　　要：对一起220 kV线路短路故障跳闸进行分析,找出PRS-753型线路保护装置与PSL-603型线路保护装置2套保护装置针对发展性故障动作报告不一致的原因和影响保护动作行为的现场缺陷,提出保护装置报文应用的优化逻辑,以使高压线路发生此类故障时,双重化保护装置能够准确地、完整地记录故障情况和保护动作情况,以方便继电保护人员分析处理故障缺陷。Through analyzing a 220 kV line short-circuit fault trip,the reasons for the inconsistent action reports of the PRS-753 line protection device and the PSL-603 line protection device for the development of the fault and the scene defects that affect the protection action are found out.The optimization logic of the application of the protection device message is proposed,so that the dual protection device can accurately and completely record the fault condition and protection action when such a fault occurs in the high-voltage line,so as to make it easier for the relay protection personnel to analyze and deal with the fault defect.
