广东韶关电网鸟害跳闸故障统计分析及防护
|
摘要
针对广东韶关电网近年来深受鸟害故障影响,根据2003-2016年韶关电网输电线路跳闸故障情况,重点统计分析了鸟害故障数据。统计分析发现:该地区电网年均鸟害故障发生率为9.13%,鸟害故障已成为仅次于雷击灾害的输电线路跳闸第二大原因。研究表明:该地区鸟巢故障占比46.67%成为鸟害故障的首要故障类型,鸟害故障主要集中在110 kV和220 kV输电线路,发生在6-8时的鸟害故障占比26.67%,发生在3-7月份的鸟害故障占比70%。研究结果可为输电线路运行维护中的鸟害防治工作提供借鉴和参考。
In recent years, Guangdong Shaoguan power grid has been affected by bird damage. According to the fault conditions of transmission lines in Shaoguan during 2003-2016, the data of bird damage were analyzed statistically. The statistical analysis shows that the annual incidence of avian diseases in the power grid is 9.13%, and the avian disturbance has become the second largest cause of transmission line tripping after the lightning strikes. The research shows that 46.67% of the bird's nest failure in the area is the primary failure type of bird damage. The bird damage mainly concentrates on the 110 kV and 220 kV transmission lines, accounting for 26.67% of the bird damage occurring from 6:00 to 8:00,March to July bird damage accounted for 70%. The research results can provide reference for prevention and control of bird strike work in the maintenance operation of the transmission line.
