随着国民经济的不断发展,工农业用水日益增长,但可供利用的水资源有限,使得供水与需水矛盾加剧。因此,对流域内或流域间的水库进行联合调度和管理,将有限的水资源统筹安排、挖掘潜力、充分发挥现有工程的效益、提高供水的保证程度即对水库实施优化调度很有现实意义。本文应用系统分析方法,建立了灌溉水库群优化调度的聚合分解(AD)模型,以保证在系统整体效益最优条件下得出各库的最佳运行策略,从而使水库的运行管理建立在科学的基础之上。

A sharp contradiction between water-supply and water-demand has been created because the water resources which can be used are limited and the water-demand of industry and agriculture is increasing with the development of national economy. Therefore, it is of practical significance to apply optimal regulation to reservoirs. Using systematic analysis method, the study herein establishes an aggregation-disaggregation model for the optimal regulation of multireservoirs, so as to obtain the optimal operation policy whilst keeping the whole benefit of the reservoir system optimal. Accordingly, the operation and management of reservoirs will be based on science.
