Automatic simulation processing method and device for switch operation failure

The invention discloses an automatic simulation processing method and device for a switch operation refusing fault. The method comprises the following steps: acquiring basic data used for performing simulation processing on a switch operation refusing fault in a power system; based on the basic data, multiple times of simulation processing is carried out on the switch operation refusal fault, multiple processing results are obtained, and the switch operation refusal fault is a fault corresponding to a single-phase switch when a single-phase short-circuit fault occurs in the power system or when a three-phase short-circuit fault occurs in the power system, one phase of switch cannot be switched off; and performing statistical analysis on the plurality of processing results to obtain a statistical analysis result. According to the method, the technical problem that the risk condition of power grid instability caused by switch refusal operation calculated and identified by using a traditional method in related t
