AbstractWith increased occurrences of forest fire, the short-term reliability of power transmission lines need to be re-evaluated considering the impact of forest fire on the aging of transmission lines. How to include the impacts from forest fire on line aging in a comprehensive way becomes an important issue for the study of line failure probability. In this paper, a method is proposed to evaluate the impact of forest fire on line aging degree based on dynamic heat balance equation and Weibull distribution. The method will help maintenance staffs to assess the damage level of transmission lines. The method is tested by a contrast experiment and a case study with real meteorological data. Simulation results show that forest fire can greatly threaten the reliability of power transmission lines, while during this process, flame characteristics, wind and load ratio could be the major factors that affect the line reliability. With the results obtained, this paper also provides the system operator with valuable instructions on how to reduce the damages caused by fire to transmission lines.
