Research on Power System Fault Recovery Strategy Considering the Spatial and Temporal Influence of Typhoon Weather

In order to evaluate the fault risk in typhoon weather and provide the fault recovery strategy quickly and accurately after the fault occurs, a method of generating the fault recovery strategy of power system considering the influence of typhoon weather is proposed. Firstly, the typhoon transit condition is simulated, and the fault probability model considering the influence of typhoon spatial and temporal characteristics is obtained according to the improved Rankine model. Then, combined with the fault probability simulation system fault scenario, the grid fault recovery model is established to minimize the system load loss, and the approximate linearization method is used to transform and solve the model. Finally, an actual urban power grid is taken as an example for analysis and verification, and the effective recovery strategy of power system under different fault scenarios is obtained.
