摘要

目前

中国已建成相当规模的直流输电网。直流输电线路的快速建设和大规模运营带来的是一系列的直流线路管理和运行问题

而直流输电线路雷害防治工作正是管理运行工作中的一个重点和难点。由于中国直流输电线路雷害防治起步较晚

且有单一线路雷击数据量偏少、计算模型存在局限性等问题

传统的计算和评估方法较难真实地反映直流输电线路的实际雷害情况。笔者正是以上述问题为出发点

搜集了大量的雷击闪络数据

整体上把握了国内直流输电线路的雷害现状

并利用数据挖掘和敏感性因素分析等手段得到了一定的直流线路雷害特征

为运行管理部门开展防雷工作提供一定的参考和依据。

Abstract

In China

a considerable scale of DC transmission networks have been built. However

the rapid development and large-scale operation of the DC transmission lines have brought a number of issues in management

of which the lightning prevention is a important but difficult issue. The existing calculation and assessment model cannot effectively reflect real lightning risk of the DC transmission lines owing to its limitation in calculation and lack of lightning data record of single DC transmission line. Therefore

the authors collected a large amount of lightning flashover data to describe the entire lightning damage status of DC transmission lines in China. Further

the data mining technology and sensitive factor analysis are employeed for discovering the lightning damage characteristics of DC transmission lines in order to provide a reference for lightning prevention.
