摘　　要：针对云南某电网近年来深受鸟害故障影响,统计2013~2022年该地区输电线路跳闸故障数据,从杆塔形式、导线空间分布、跳闸月度分布、每日时段分布等多维度开展故障原因和规律分析。统计分析发现:输电线路鸟害故障成为仅次于雷击、山火的第三大故障原因。研究表明:该地区因鸟粪引起故障为首要故障类型,鸟害故障主要集中在110 kV和220 kV输电线路,发生在11月~次年4月的鸟害故障占比88.52%,发生在21时~次日7时的鸟害故障占比89.83%。研究结果可为输电线路防鸟害工作提供借鉴和参考。In view of the deep impact of bird damage failures on a power grid in Yunnan in recent years,statistical data on transmission line trip failures in a power grid in Yunnan from 2013 to 2020 were collected,and fault causes and rules were analyzed from multiple dimensions such as tower form,conductor spatial distribution,monthly trip distribution,and daily time interval distribution.Statistical analysis shows that bird damage fault on transmission lines has become the third largest cause of fault after lightning strikes and mountain fires.Research shows that bird dropping-induced failures are the primary type of failures in this region,with bird damage failures mainly concentrated on 110 kV and 220 kV transmission lines.The proportion of bird damage failures occurring from November to April of the next year is 88%,and the proportion of bird damage failures occurring from 7:00 am on the 21st to the next day is 90%.The research results provide reference for the prevention of bird damage on transmission lines.
