摘要
针时某起由山火引起的线路跳闸事故,结合线路故障巡视、气象资料、地理环境等因素,确定故障位置,分析故障原因,最后在研究山火导致线路跳闸机理、分析山火多发原因及总结故障特点的基础上,提出有效的防范措施,最大限度地减少山火造成的跳闸事故,确保电网安全可靠运行。
In this paper, the fault sites were determined and the reason of failures were analyzed for an actual transmission line tripping accident by wildfires, combined with fault inspection, meteorological data and geographical environment etc. factor. Finally, countermeasures were proposed in this article with research of tripping mechanism caused by wildfires, analysis cause of wildfires prone and conclusion characteristics of faults, to reduce the trip-out fault caused by wildfires to the minimum extent, moreover insure grid running safety and reliability.
