Dynamic Mechanism of Transmission Lines for Complex Weather

This paper studies the transmission line fault mechanism analysis considering complex weather substation. Firstly, the excess penalty variable weight entropy theory is introduced to establish a complex weather risk source model considering lightning, rainfall, wind, temperature, relative humidity and other meteorological factors; Then, the model is used to calculate the corresponding comprehensive meteorological factors; Finally, based on the electrical equipment health index model, a transmission line fault rate correction method for meteorological risk sources is proposed. The actual weather data of a region in Liaoning, China are collected and simulated in IEEE118 node system, the experimental results show the effectiveness of this method.
