摘要
输电线路沿线走廊的雷电活动参数的统计对线路雷击故障的风险性与地闪密度相关性分析有重大的意义。基于雷电定位系统对发生在红沿河核电站周围的220 kV输电线路沿线引雷区间的地闪密度等参数进行统计分析,分析比较了2013—2017年各年的线路沿线的地闪密度情况,并结合线路经过区域的地形地貌,分段统计各个杆塔区段的落雷情况。分析结果表明,在线路近海的高山上其地闪密度较高,超出其他杆塔区段地闪密度均值的40%左右。将线路沿线雷电活动的统计结果与线路杆塔所处的环境结合起来,针对特定杆塔区域给出差异化的防雷措施,减少线路的雷击跳闸事故,提高线路的耐雷水平,保证线路安全、持续运行。
The statistics of lightning activity parameters along the corridor of the transmission line are of great significance for the analysis of the correlation between the risk of lightning strike failure and the ground flash density.Based on the lightning location system, this paper analyzes the parameters such as the ground flash density of the lightning-distribution section along the 220 kV transmission line around the Hongyanhe nuclear power station.It analyzes and compares the ground-flash density along the line in each year from 2013 to 2017. The analysis results show that the ground flash density is higher in the high mountains near the line, which is more than 40% of the average flash density of other tower sections. It combines the statistical results of lightning activity along the line with the environment where the line tower is located,and provides differentiated lightning protection measures for specific tower areas, which reducing lightning strike accidents,improving the lightning level,ensuring the safety and continuity of the line.
