Disposal decision-making method based on fault evolution path

The invention discloses a disposal decision-making method based on a fault evolution path, and the method comprises the steps: obtaining a power grid operation mode and an anticipated fault, and providing basic input for subsequent power grid safety analysis; according to the obtained power grid operation mode data, carrying out power grid safety analysis of an anticipated fault; judging whether the frequency is out of limit or not, and if the frequency is out of limit, performing frequency out-of-limit assistant decision; judging whether a condition of equipment overload or section out-of-limit exists or not; and judging whether a voltage out-of-limit condition exists or not. According to the method, hierarchical analysis and decision making of the processing decision according to the fault evolution stage can be realized, the practicability and availability of the auxiliary decision can be improved, the intelligent level of power grid fault processing can be improved, the processingof the actual fault of th
