摘　　要：针对水电站装机容量选择和确定计算方法所存在的问题,提出了基于水库能的装机容量计算方法。首先将通过分析水库水体的水能、动能和压能的分布、输移和转换形式,提出了水库能的概念。以发电量最大化和水能利用最大化为目标,提出水电站装机容量的计算方法。以红水河流域某一水电站为例进行了仿真计算。计算结果表明,水库可用水量、入库流量、洪水流量对水电站装机容量有较大影响。A method for modeling hydro energy,hydro-mechanical-electric coupling and optimum installation capacity of a large-scale hydroelectric plant is presented in this paper.This paper also presents a method for computing the optimal installation capacity of a hydro plant by maximizing the ratio of electric energy produced in a scheduling period and the water volume consumed by generation.Among these constraints,width,depth,controllable drainage area,allowable generating unit number,water flow and volume available of a reservoir is taken into consideration.A study example with several simulation cases is carried out to illustrate flexibility,adaptability,applicability of the proposed method.
