摘要
针对智能变电站合并单元更换过程中一起保护装置拒动事件,分析了保护装置拒动的原因,结合智能变电站的检修机制,阐述了智能变电站正常检修和智能装置异常条件下检修处理机制,并针对各种不同设备保护装置,提出相应的检修处理方式。对今后的智能变电站设计、检修、运行提供借鉴作用。
In view of a protection malfunction accident during merging unit replacement,this article analyzed the causes of the accident. Combined with the maintenance mechanisms of smart substation, the maintenance disposal methods under normal maintenance condition and abnormal condition are described. Corresponding maintaining methods are put forward for all kinds of protective devices,which could provide references for the design, maintenance and operation of smart substations.
