摘要
现行水电站经济运行考核评估方法根据实际来水以及初步设计和调度图(对于无调节能力电站则根据考核水位)计算考核电量,核心概念是节水增发电量。本文提出以优化挖潜为目的的新考核评估思路,提出基于"理论最大发电量(效益)"的"发电完成率"概念,采用精细模拟与优化调度耦合模型初步建立了新的评估方法。以三峡-葛洲坝梯级水电站经济运行的评估为例,对比分析了两种方法的特点。
The existing assessment method of economic operation of hydropower plant based on initial design and operation chart emphasizes an conception of increasing power output by using the water saved.In this paper,a new assessment method of accurate simulation and operation optimization is presented.In this method,a theoretical maximum output is obtained first,and then the ratio of actual output over this maximum and some other factors are used to estimate the operation level.A case study of the Three Gorges-Gezhouba cascade hydropower plants shows advantages of the new method.
