江西电网涉鸟故障分析及防范

为分析江西电网涉鸟故障原因及规律,通过统计2009~2016年涉鸟故障,发现涉鸟故障主要发生在农田或邻近水源低海拔地区,4~7月为涉鸟故障发生的高峰期,且鸟巢类故障主要发生在凌晨和早晨,而鸟粪类故障主要发生在夜间至凌晨。同时,涉鸟故障发生的概率还与杆塔的电压等级、杆塔结构型式、排列方式、相别和天气有关。为更好地防范涉鸟故障的发生,综合考虑鸟类分布、人类干扰度、地理环境和运行经验等要素,提出了涉鸟故障差异化防治措施。研究成果对于降低涉鸟故障率,保障电网安全运行有重要意义。

Analysis and Prevention of Bird related Fault in Jiangxi Power Grid

In order to analyze the causes and laws of bird related fault in Jiangxi power grid, the bird related fault in 2009 2016 years was analyzed, and it was found that the bird related fault occurred mainly in the low altitude areas of farmland or adjacent water sources. The peak of bird related fault appeared from April to July, and the bird''s nest fault mainly occurred before dawn and in the morning while the guano related fault mainly occurred in the night to early morning. At the same time, the probability of the occurrence of bird related fault was related to the voltage level of the tower, the tower structure, the arrangement, the phase and the weather. In order to better prevent the occurrence of bird related fault, considering the distribution of birds, human disturbance, geographical environment and operation experience and other factors, this paper puts forward differential control measures to control the bird related fault. The research results are of great significance for reducing bird failure rate and ensuring the safe operation of power grid.
