摘　　要：为克服卫星和图像监测等方法在输电线路山火监测告警中存在的不足,提出一种基于新一代天气雷达组网监测的输电线路山火自动识别算法。从某地区历史山火的新一代天气雷达回波数据样本库出发,分析山火的新一代天气雷达回波特征,建立山火雷达回波的特征量集合并提出阈值判据。采用四邻域法对山火回波块进行快速识别,通过滤除背景杂波提高山火回波识别准确率,结合多线程并行分析方法,实现多部雷达组网对山火的自动识别;基于改进型杆塔定位方法,实现受山火影响的输电线路杆塔快速定位与告警。该算法在某省级电网中的应用表明其晴好天气下的识别准确率接近80%,为输电线路山火的监测告警提供一种新手段,可与卫星监测方法互为验证和补充。In order to overcome the defects of existing methods on monitoring and warning of the wild fire near transmission lines,such as satellite and image monitoring,an automatic identification algorithm of wild fire near transmission lines based on the CINRAD-net monitoring was proposed in this paper.According to a sample database of CINRAD echoes for historical wild fires in a certain area,the characteristics of the CINRAD echoes for wild fire were analyzed.Thereby,the features characterizing CINRAD echoes were constructed and the threshold criteria were given.Then,the four-neighborhood algorithm was used to automatically identify the wild fire,and the radar clutter was filtered to improve the identifying accuracy.Combined with multithread processing method,the automatic identification for wild fire was realized.Based on an improved tower location method,fast locating and warning of wild fire were achieved for transmission line towers.The application in a provincial power grid has showed that the proposed method has an identification accuracy of nearly 80%in sunny days.This paper provided a new way for monitoring and warning of the wild fire near transmission lines,which can be verification and a supplement for satellite monitoring method.
