Maintenance Scheduling System Considering System Security Constraints

Equipment maintenance is a very import part of power system operation. The scientific, rational and practical maintenance schedules are helpful to improve the security and economy of the power system operation and improve the modernization level and profit efficiency of the enterprises.this paper proposes a new model for distribution maintenance scheduling and try to find the most economical maintenance schedule By heuristics. Inocording to solve the security of maintenance schedules,this paper schemes out a practicality soft of static safety analysis which based on existing arithmetic and index of contingency analysis.Once more,this paper apply this soft to security of maintenance schedules.The proposed model and method of maintenance schedules and static safety analysis are applied to a practical system, and numerical results verify the correctness and validity of them.
