| 摘 要： | 提出了一种基于时空聚类算法的雷电地闪活动规律分析方法.利用广东佛山地区近十年的海量落雷数据,研究雷电地闪活动路线与地形地貌、河流、高程等的相关性,提取雷电地闪活动的典型发展通道.结果表明,地闪活动易发生在河流附近,与高程关系不明显,大部分雷击杆塔故障发生在雷电活跃主通道,为输电线路的差异化防雷、预警提供重要依据.

| Abstract: | A method of lightning ground flashover activities law analysis based on time and space clustering algorithm is proposed.Based on massive lightning data of Foshan in recent ten years,the relation with topography,rivers,elevation,etc.of lightning activity are researched,and the typical develop passageways of lightning activity are extracted.The results show that lightning is easy to occur near the river,and has no obvious relation with elevation,most of lightning tower faults occur in the main lightning active passageway,the important basis is provided for different lightning protection and warning of transmission line. |

| Keywords: | lightning activities time and space clustering main lightning passageway lightning time zone elevation |
