摘要

海南省属于热带季风气候

雷雨众多

地闪密度远高于平均值

在研究输电线路防雷时需要特别注意地闪密度对雷击故障的影响。文中依据海南省67条35、110、220 k V输电线路资料参数及海南省输电线路近8年的运行报告、事故报告和雷电定位系统的数据绘制了地闪密度图

实际雷击故障分布图

拟合了海南省雷暴日与地闪密度的分布曲线

针对CIGRE经验公式及QGDW 672—2011标准不能准确反映海南省雷电活动的不足

提出了针对海南省地闪密度的分级方法

并基于皮尔逊相关系数分析了CIRGE标准及针对海南省标准下的地闪密度与实际雷击跳闸率的相关性

对海南省的输电线路差异化防雷具有指导意义。

Abstract

For lightning protection research of transmission lines in Hainan Province

it is necessary to pay more attention to the impact of cloud-to-ground lightning density on lightning trip rate due to the particular climate.In this study

the maps of cloud-to-ground lightning density and actual lightning failure distribution were drawn according to the data of 67 transmission lines with the voltage of 35

110 or 220 kV in Hainan Province

as well as the operation reports

accident reports

and lightning positioning system data of Hainan power transmission lines in recent 8 years.And the distribution curves of thunderstorm days and cloud-to-ground lightning density were fitted.Because the CIGRE’s empirical formula and the QGDW 672-2011 standard could not accurately reflect the lightning activity in Hainan Province

a classification method of cloud-to-ground lightning density for Hainan Province was put forward.The Pearson correlation coefficient was used to analyze the CIGRE standard and the relation between cloud-toground lightning density and actual lightning trip rate of transmission line in Hainan Province.
