Abstract

The invention provides an electric transmission line forest fire grade forecasting method based on five factors. The electric transmission line forest fire grade forecasting method based on the five factors comprises the following steps of (1) confirming the value of a fire using high-incidence season factor alpha, (2) confirming the value of a vegetation factor beta, (3) conforming the value of a burning factor gamma, (4) confirming the value of a meteorological factor delta, (5) confirming the value of a rainfall factor epsilon, (6) calculating an electric transmission line forest fire forecasting index X, and (7) obtaining forest fire forecasting grades of the electric transmission line to be forecasted according to the forest fire forecasting index X. The electric transmission line forest fire grade forecasting method based on the five factors is practical, convenient to implement, fast, strong in practicability, convenient to operate, high in forecasting accuracy and high in reaction speed; strong guidance can be provided for a maintenance unit of electric transmission lines to set forest fire prevention strategies and deploy forest fire prevention measures, and important functions performed for maintaining the safe and stable operation of an electric grid are indispensable.

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution, and in particular relates to a five-factor-based method for predicting the grade of mountain fires in power transmission lines. Background technique [0002] With the progress of society, electricity plays an increasingly important role in human production and life. However, wildfires around transmission lines often cause transmission line trips, which poses a serious threat to the stability of the grid structure and affects normal power supply. , Seriously endanger industrial production and people's lives. [0003] At present, the known prior art includes forest fire risk meteorological level forecasting and transmission line mountain fire forecasting, and transmission line mountain fire level forecasting has not yet been carried out. In actual work, it is necessary to carry out forest fire level forecasting. By carrying out this work, the prediction accuracy of tran...
