水电站群装机容量优化选择模型及其应用

本文从电力系统和水电站群的角度出发，考虑电站的必然联系和水电群的整体运行，建立了规划水电站装机容量优化选择数学模型。该模型由水电群优化补偿调节计算子模型，水电群总工作容量优选子模型和规划水电站工作容量优化分配子模型三个子模型构成，通过三个子模型的逐步求解和多轮迭代，最后即可得到收敛的优化装机解。本文针对规划水电站工作容量优化分配子模型给出了增量判别求解方法。最后是将本模型方法应用于云南大朝山水电站

Model for Optimizing Installation Capacity of Group of Hydropower Stations and Its Application

On the view of power system and hydropower growp, this paper considers various re-lationship among each hydropower statlon for determinlng thelr installed capacity. So, an optimizationmodel is establised. It consists of three submodels called Optimal Dispatching Calculation of Hy-dropower Group, Determination of Working Capacity of Hydropower Group and Optimal Allocationof Working Capacity among Planning Stations, respectively. Through solving three submodels step bystep and round iterations, the solution of optimal installed capacity can be obtained. Moreover, the in-cremental criteria method is given to slove optirnal allocation subproblem in the third submodel. Atlast, an example of defermlnlng lnstalled capality of Dachaoshan Hydropower Station in YunnanProvince is provided. The result shows it will be bctween l200~ 1260 MW.
