Study on water supply dispatching rules of reservoir group diversion with interval water priority
[Objective]With the development and improvement of cross-basin water transfer project,sluice dams without regula-ting capacity gradually participate in the operation together with reservoirs,which poses a greater challenge to the formulation of operation rules considering the abundant and dry characteristics of multi-basin and regulating capacity of multi-reservoirs.[Methods]This paper proposes the principle of prioritizing the use of interval water relative to reservoirs in water transfer,so as to construct the dispatching model with the minimum total abandoned water in the system,and obtain the dispatching rules by the improved genetic algorithm.In addition,taking Shihu-Longwan-Biliuhe Reservoir and Haiyuting Dam as a case study,the pro-ject of connecting the ocean to the water transfer is compared.[Results]The dispatching rule of preferential utilization of water in the interval avoids the deep damage of the system and meets the urban water supply demand with 95％guarantee rate,compared with conventional dispatching.The annual average water diversion increases by 79 million m3,and the annual average water abandonment decreases by 210 million m3.[Conclusion]It improves the utilization rate of the interval water in the upstream sec-tion of sluice dam and the water efficiency of the system.This research provides scientific reference and technical support for the operation of cross-basin water transfer system with sluice dam.
