本文阐述在江河流域水力开发的初步可行性及可行性研究阶段使用的一种模型。这种模型可以对若干种可供选择的开发方案的主要参数及运行特性进行计算和最优化研究,这些开发方案也包括梯级水电站的分期建设。所使用的最优化标准的净效益是最大的。使用综合的水库“供水量”曲线,可经济地利用计算机时间对长期的开发规划进行计算。 This article describes a model used in the preliminary feasibility and feasibility study of hydraulic development in river basins. This model allows the calculation and optimization of the main parameters and operating characteristics of a number of alternative development options, including the staging of cascade hydropower stations. The net benefit of the optimization standard used is the largest. Using a comprehensive reservoir “water volume” curve, the long-term development planning can be calculated economically using computer time.
