| Summary: | Abstract
In extreme weather, the line trip-out events caused by the wind swing of the transmission line occur frequently, severely affecting the normal operation of the power system. Since the structure of the operating transmission line is difficult to be improved, wind swing flashover risk assessment is of great significance for the operating transmission lines. In this paper, a transmission line wind swing flashover risk assessment model based on the matter-element extension model is proposed. The analytic hierarchy process (AHP) and entropy weight method are applied to comprehensively calculate the weight value of the selected assessment index. This model can assess the early warning level of a certain tower unit in the transmission line. Finally, the feasibility and effectiveness of the proposed assessment model are verified by practical examples. |
