An evaluation method of wildfire risk in transmission lines based on TOPSIS and cloud model
XU Hua, Dangfei Dang · 2024
In China, the transmission lines of ultra-high voltage power grids often cross areas with lush vegetation. In order to reduce the risk of transmission line tripping and outage, this paper proposes an evaluation method of wildfire risk in transmission lines integrating TOPSIS and cloud model. An index-based wildfire risk assessment system is first built for transmission line, and the key factors are identified according to TOPSIS method. By using cloud model, the wildfire risk level of transmission line can be finally determined. The applicability is demonstrated by a case study, and the result indicates that this method has the ability to effectively assess the wildfire risk of transmission lines and accurately identify the key factors.
