【摘要】：为研究湖南电网鸟害故障特征并针对性地提出防范措施,对湖南电网鸟类活动情况进行观察统计,发现湖南省的鸟类有463种,其中易引起电网涉鸟故障的鸟类主要有13种。对2006—2016年湖南架空输电线路鸟害故障进行统计分析,发现湖南电网涉鸟故障点在湖南省呈倒V形分布,这与湖南鸟类迁徙路径及电网鸟巢分布基本相符;故障点多在水源附近,发生在2:00—8:00间的鸟害故障占鸟害总次数的67.60%,发生在每年10月份至次年1月份的鸟害故障占鸟害总数的64.79%;故障类型以鸟粪类为主,占比85.92%;中相发生涉鸟故障的概率远高于两边相,约为后者2倍;鸟害故障主要集中在110和220 k V输电线路,且V型串和悬垂I串发生鸟害故障的概率相对较高;湖南电网涉鸟故障与绝缘子类型的关系不大。对湖南电网防鸟装置应用情况进行了统计和评估。提出了开展鸟类活动观测、绘制鸟害风险分布图、开展鸟害评估并采取治理措施、将防鸟害纳入新建线路可研评审的建议。
[Abstract]:In order to study the characteristics of bird damage faults in Hunan Power Grid and put forward some preventive measures, we observed and counted the bird activities in Hunan Power Grid, and found that there are 463 species of birds in Hunan Province. There are 13 species of birds that are liable to bird fault in power grid. Statistical analysis on bird damage fault of overhead transmission line in Hunan Province from 2006 to 2016 shows that bird related fault point in Hunan power grid is in inverted V shape distribution. This is basically consistent with the migration path of birds in Hunan Province and the distribution of bird nests in the power grid; most of the fault points are near the water source. Bird damage faults occurring between 2: 00-8: 00 account for 67.60% of the total number of bird hazards, and bird damage faults occurring between October and January each year account for 64.79% of the total number of bird hazards. The types of faults are mainly bird dung, accounting for 85.92%. The probability of bird related faults occurring in the middle phase is much higher than that on both sides. Bird damage faults are mainly concentrated in 110 and 220 kV transmission lines, and the probability of bird damage faults in V-type string and drape I string is relatively high. The relationship between bird fault and insulator type in Hunan power grid is not significant. The application of bird control device in Hunan power grid is analyzed and evaluated. It is proposed to carry out bird activity observation and draw the distribution map of bird hazard risk. To carry out bird damage assessment and take measures to control bird damage.
