【摘要】 科学、合理、实用的检修计划有利于提高电力系统运行的可靠性,能够提高电力企业的现代化管理水平和经济效益。本文在研究供电系统检修计划制定现状的基础上,通过分析供电系统检修计划优化问题的多目标性、随机性、关系复杂性等特点,提出了一种以停电损失的负荷最小为目标的整数规划模型。本文的数学模型根据检修操作的同时性、顺序性和互斥性要求,建立了约束条件;然后对模型进行加速改进,即首先处理等式约束来降低维数,并对设备按照重要性等级和影响的负荷大小进行排序,通过这样的处理,有效的减少了枚举的次数;最后应用枚举法,得到全局最优解。通过算例验证了该方法的实用性和有效性。采用本文提出的优化方法,使编制出的检修计划更合理,提高了电力系统供电的安全性和可靠性,保证节约人力、物力,减少检修所造成的损失。

【Abstract】 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. The optimization of maintenance scheduling in power supply system has the traits, such as multiple goals, highly randomicity, complex restriction relation, etc. 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.
