摘　　要：保护动作行为分析是查找动作原因、锁定故障位置、处理设备缺陷以及恢复电力供应必不可少的重要环节。文章以一起110 kV主变后备保护复杂动作案例为例展开分析,从动作前电网运行方式、监控后台报文信息时序、现场一二次设备状态测试检查等方面入手,通过层层分析繁杂的保护动作过程,分析保护动作原因,精准锁定故障位置,准确评价保护动作行为,并总结经验,归纳复杂继电保护动作后分析的思路与方法。The analysis of protection action behavior is an important part of finding the cause of action,locking the fault location,dealing with equipment defects and restoring power supply.The article takes a 110 kV main transformer backup protection complex action case as an example to start the analysis,starting from the grid operation mode before the action,monitoring the timing of background message information,on-site testing and inspection of the state of the primary and secondary equipment,etc.,through the layer-by-layer analysis of the complicated protection action process,to analyze the reasons for the protection action,accurately locking the location of the fault,accurately evaluating the behavior of the protection action,and summarize the experience,summarize the ideas and methods of the analysis of the complex relay protection after action.The idea and method of analyzing after the action of complex relay protection is summarized by summarizing the experience.
