摘　　要：针对输电线路附近树木生长快,发现难度大的问题,提出一种基于数字孪生的输电线路树木距离告警方法。通过视频摄像装置对输电线路下方的树木进行识别,获取树木的特征信息;构建输电线路树木的数字孪生模型,对树木的生长周期和可能造成的输电线路危害进行仿真;通过贝叶斯网络对树木可能造成的输电线路事故进行置信度分析,生成输电线路树木距离告警事件,并通过移动作业终端提醒运行检修人员进行数障处理。通过对输电线路树木距离告警的实例分析,验证本方法的有效和可行性。In order to solve the problem of fast growth of trees near distribution lines,a distance alarm method based on digital generation is proposed.The video camera device is used to identify the trees under the distribution line to obtain the characteristic information of the trees.The digital contracture model of the distribution line trees is constructed to simulate the growth cycle of the trees and the possible harm of the distribution line.The Bayesian network is used to analyze the confidence of the distribution line accidents caused by the trees to generate the distribution line accidents.The distance alarm event of the line trees is constructed,and reminds the operation and maintenance personnel to deal with the number of obstacles through the mobile operation terminal.The effectiveness and feasibility of this method are verified by the example analysis of the distribution line tree distance alarm.
