毛家村水库长期优化调度研究

Research on Long-Term Optimal Dispatching of Maojiacun Reservoir

针对毛家村水库及电站的实际情况,根据动态规划的最优性原理,建立了以水电站年平均发电量最大为目标函数,以各时段水库的发电用水为决策变量的水库长期优化调度模型;并对径流资料进行分析,建立了随机模型;对样本径流资料和模拟序列分别进行了长期优化调度计算,得到水库的最优调度过程.

With regard to the practical situation of Maojiacun reservoir and power station, an optimal model of reservoir operations is constructed on the basis of the optimal principle in dynamic programming. The objective function and the decision - making variables of this model are respectively annual average generation power and water used at every stage. Runoff hydrology data are then analyzed to set up a stochastic model. The optimal dispatching is therefore obtained through a long - term calculation of the runoff data and simulated sequences.
