A transmission line fault rate correction method for meteorological risk sources is proposed in this paper. Firstly, a complex weather risk source model considering lightning, rainfall, wind, temperature, relative humidity and other meteorological factors is established by introducing the overrun penalty variable weight entropy theory, and the corresponding comprehensive meteorological factors are calculated by using the model; Then, based on the electrical equipment health index model, a transmission line fault rate correction method based on meteorological risk sources is designed. Finally, the effectiveness of the method is verified by simulation experiments.
