Research On Maintenance Scheduling Optimization Of Distribution Network

The scientific, rational and practical maintenance scheduling are helpful to improve the stability of the power system operation and improve the modernization level and profit efficiency of the enterprises. By analyzing these problems and on basis of studying the current situation of the maintenance scheduling design, an optimization method has been presented in this paper. The goal function is the minimal power cutting lost load. The optimal solution can be got by Integer Programming module. The module's restriction can be established by the synchronous, mutually exclusive and ordinal need. Then an accelerated amelioration has acted on the module, which firstly reduce dimension by dealing with equation restriction, then sort the equipments by their voltage grade and related cutting lost load. By these the amount of enumerating can be reduced effectively. Lastly the global optimized solution can be got by enumerating. The practicality and efficiency of the method had been proved by the example. With the optimized method in this paper, it can make the plan more rational, decrease the loss of power cut, improve the safety and reliability of power supply system and enhance the economical efficiency and social efficiency of the enterprises. A useful attempt is made in this thesis to digitalize the production and operation of power supply enterprises.
