Abstract
Wildfires have become an important factor threatening the safe and stable operation of transmission lines, and large-scale wildfires can significantly reduce the air gap insulation level of transmission lines and cause line tripping. Therefore, based on the principle of cellular automata and Wang Zhengfei's model of wildfire spread, this paper analyzes in detail the effects of factors such as slope, wind speed, wind direction, and fuel type on the speed of wildfire spread and the area of the fire site, and predicts the time when the wildfire arrives below the transmission line. The results indicate that the established model can preliminarily reflect the spread law of wildfires, and has a certain guiding role for the safe and stable operation of the power grid.
