A review of risk assessment of transmission lines under wildfire disaster

In recent years, the frequent occurrence of wildfire disasters in China has seriously threatened the stable operation of transmission lines. This paper expounds the mechanism of transmission line fault caused by wildfire disaster, introduces a variety of wildfire monitoring and transmission line fault analysis methods, analyzes the technical principles, advantages and disadvantages of transmission line fire risk assessment methods based on BP neural network, naive Bayesian network and analytic hierarchy process, and summarizes and analyzes the advantages and disadvantages of three different assessment methods, so as to improve the risk assessment of transmission lines under wildfire disaster.
