摘　　要：指出已有的电站设备维修优化理论缺乏对维修方案优化的相关研究,只能达到技术最优或者成本最经济,且没有相关的量化标准和定量论证。提出了基于价值工程的电站设备维修方案优化方法,认为该方法统筹维修技术与经济成本,综合考虑设备的设计、使用和维修等阶段,以维修方案的效用比最高为优化目标。从理论上对维修方案的内容和维修方案优化的过程进行了阐述。针对某1 000 MW汽轮发电机组的实例,,利用层次分析法等进行定量分析后得出最优的维修实施方案。For the lack of related research on maintenance optimization, existing power plant equipment maintenance optimization theory can only achieve the aim of being optimal in technology or being economic in cost. There is no relevant quantitative criteria and quantitative demonstration. To solve the above problem, power plant equipment maintenance program optimization methods based on value engineering is presented in this paper. This method takes value engineering principles into concern of the maintenance program optimization, cordinates maintenance technique and economy cost, and considers stages of the equipment design, use and maintenance comprehensively. When the maximum effectiveness of the maintenanee program is set as the optimal target, the optimal implementation plan of maintenance is concluded, by using the AHP and other quantitative analysis. In addition, the content of the maintenance program and the optimizing process of maintenance program are described in this paper theoretically. A case analysis of a 1 000 MW turbine-generator unit shows that the method is simple, effective, and easy to be implemented in engineering practice.
