摘要
文中阐述了山火对输电线路产生的影响,简述了输电线路山火监测技术的研究现状,针对目前输电线路山火监测方案存在的不足,提出采用激光雷达系统监测输电线路山火的方案。文中从激光雷达监测原理出发,分析了激光雷达系统在监测输电线路上引发的山火具有一定的有效性,并通过模拟实验验证了激光雷达系统可用于输电线路上山火的监测。进一步依据激光雷达系统存在盲区的特点,从理论上推导了激光雷达在用于输电线路山火监测时的最优安装位置。
The impact of wildfire on power transmission lines and the status of research on monitoring wlldllre arounu power transmission line are elaborated in this paper. Aiming at the present shortcomings of monitoring wildfire around power transmission line, a solution of monitoring wildfire around power transmission line based on lidar is proposed. Starting from the principle of Lidar monitoring, Lidar system used in the monitoring wildfire around power transmission is analyzed, and the experiments prove its validity. Furthermore, according to the characteristic of Lidar system＇ s dead zone, the optimal installation position for Lidar to monitor wildfire around power transmission line is derived on theory.
