Research on Optimization Management Method of Power System Overhaul Plan
Aiming at the problems existing in the current power system maintenance plan management,a maintenance plan management method based on multi-objective optimization is proposed.The method establishes a maintenance plan optimization model with multiple objectives,including equipment health status,maintenance resource constraints and grid operation risk,etc.The improved genetic algorithm is used to solve the model,and the optimal maintenance plan that takes into account each objective is obtained.Through simulation analysis,it is proved that this method can effectively balance the maintenance cost,equipment reliability and grid risk,and can save 15％of maintenance cost,reduce 12％of equipment failure rate and 20％of grid risk index compared with the traditional method.
