摘要

高比例可再生能源并网需建设更多的交直流输电网，再生能源输电不可避免经过山火高发区域。为提升输电线路的山火预防能力，文中研究了基于多维联合动态监测的输电线路山火风险预警和运行决策方法。发生山火时，通过多维联合的山火监测体系迅速确定火点，结合植被、地形、风速等因素，动态计算山火蔓延至输电线路的概率。通过试验研究坡度、风速对火焰条件下间隙击穿电压的影响。结合山火蔓延和考虑环境因素的击穿特性，计算输电线路的击穿跳闸概率，发布山火风险预警，提出对应的运行决策，对输电线路安全稳定运行具有重要意义。

Abstract

The high proportion of renewable energy grid connection requires the construction of more AC/DC transmission networks

and renewable energy transmission inevitably passes through areas with high wildfire incidence. For enhancing the ability of transmission lines to prevent wildfires

the risk warning and operation decision method of transmission line wildfires based on multidimensional joint dynamic monitoring is researched in this paper. In case of wildfire

the fire point is quickly determined through a multidimensional joint wildfire monitoring system

and the probability of wildfire spreading to transmission lines is dynamically calculated based on such factors as vegetation

terrain

and wind speed. The influence of slope and wind speed on gap breakdown voltage is studied by flame conditions through experiments. Based on the spread and breakdown characteristics of environmental factors

the probability of breakdown tripping of transmission lines is calculated

the wildfire risk warnings are issued

and corresponding operational decisions are proposed

which are of great significance for the safe and stable operation of transmission lines.
