A substation post-earthquake repair path optimization method and device

Abstract

This invention belongs to the technical field of post-earthquake equipment repair path and key equipment identification in substations. Specifically, it relates to a method and apparatus for optimizing post-earthquake repair paths in substations, comprising: identifying damaged equipment to be repaired in a substation after an earthquake; determining an initial repair path based on the damaged equipment using an improved genetic algorithm, and optimizing the initial repair path to obtain an optimized repair path; and repairing the damaged equipment according to the optimized repair path. The technical solution provided by this invention ensures that damaged equipment in a substation must be completely repaired or replaced before repairing the next piece of equipment, and avoids repeatedly repairing the same equipment. It satisfies the requirements of discreteness, positive integers, and no repetition of parameters, thus demonstrating good applicability to parameter optimization problems with multiple constraints. Furthermore, in practical engineering, only the earthquake damage situation of the substation needs to be investigated to quickly find the optimal post-earthquake repair path, making it more suitable for post-earthquake repair strategy decision-making.
