摘要
针对某风电场出线开关误跳闸事件,通过跳闸时段内保护动作时序及动作情况进行原因分析,查找出该事件由小电流接地选线装置整定不当导致,并根据线路运维的实际状况提出处理措施,以供小电流接地选线装置运维参考。
In view of a false tripping event of the outgoing line switch in a wind farm, the cause analysis is carried out based on its protection action sequence and action conditions during the tripping period, and it is found that the event is caused by the improper setting of the small current grounding line selection device, and according to the actual situation of the line operation and maintenance, the treatment measures are proposed so as to offer reference for the small current grounding line selection device in its operation and maintenance.
