摘要
变电站的设备检修工作不仅是保障变电站正常运行的基础,也是降低变电站全寿命周期成本(LCC),实现效用与成本相互平衡的重要途径。文中首先基于模糊时间序列法,对电气设备在寿命周期内的可靠性参数进行模糊预测,接着引入役龄回退理论,以设备LCC中检修成本和故障成本最小化为目标,建立了检修策略的优化决策模型,并运用模糊规划理论实现了模型的求解。实例应用结果显示,提出的模糊规划模型可以为变电站电气设备检修策略的制定以及变电站的全寿命周期管理提供有益参考。
Equipment maintenance in substations is the basis of normal operation as well as an important channel through which to reduce the life-cycle cost(LCC)and realize balance between the utility and the cost.Firstly,on the basis of fuzzy time series,a fuzzy prediction is made of the reliability parameters of electrical equipment in the whole life cycle.Secondly,the age reduction theory is introduced.And with minimum equipment maintenance cost and failure cost of LCC as the objective,an optimization decision model for maintenance strategy is developed.Finally,the fuzzy programming theory is used to solve the model.The application example shows that the fuzzy programming model proposed can provide valuable reference for the formulation of equipment maintenance strategy and life-cycle management in substations.
