Research And Application Of Distribution Maintenance Scheduling Methods

Equipment maintenance is a very import part of power system operation. The scientific, rational and practical maintenance schedules are helpful to improve the stability of the power system operation and improve the modernization level and profit efficiency of the enterprises.According to the rules and considerations which are based and taken into account in the practical work, this paper proposes a new model for distribution maintenance scheduling which intends to find the most economical maintenance schedule without violating any restrictions and also the paper makes a deep research of GA, SA and TS. By constructing two effective instructive rules which derive from the feature of distribution maintenance schedule and introducing TS into mutation operation of GA in the earlier generations, the proposed method improves the convergence of optimization and shortens the calculation time. The proposed model and method are applied to a practical system, and numerical results verify'the correctness and validity of them.
