摘要

国内一些老电站在设备改造方案决策过程中,往往偏重眼前利益而忽视设备全生命周期内的改造效益,从而导致改造效果差、重复改造等问题。以国内某水电站4号机组导水机构改造为例,从安全性、能效成本及政策适应性等方面分析了改造的必要性;此外,针对整体更换及大修两个比选方案,拟定了比选边界条件;在整个生命周期中,从一次性投入、运行成本、检修成本、故障成本及退役处置成本等方面进行了费用分析与计算,并将相关成本费用折算至费用净现值后,最终提出了最优的改造方案。

Abstract

In the decision-making process of equipment refurbishment, the owner of some hydropower plant often focuses on present profit and ignores the benefits of the full life cycle, and finally results in bad effort or redundant refurbishment. By taking the refurbishment of No.4 Unit distributor mechanism in a Hydropower Plant for example, the necessity of the refurbishment is analyzed from the perspectives of safety, energy efficiency cost, and policy adaptability. Besides, boundary conditions are assumed for the two alternative schemes which are equipment replacement or overhaul. Disposable investment, operation costs, maintenance costs, fault costs and decommissioning disposal costs are analyzed throughout the full life-cycle, and related costs are converted into NPV(Net Present Value). Finally, the optimal refurbishment plan is proposed.
