大型水利枢纽供水调度方式是充分发挥水库综合经济效益的重要课题,如何科学控制水库供水期消落水位、兼顾其他兴利效益并减少弃水是水库供水调度研究的关键。本文以丹江口水利枢纽为研究对象,结合南水北调中线一期工程规划设计成果和中线工程水量调度方案编制要求,以满足汉江中下游、清泉沟、南水北调中线三供水对象的供水任务需求为目标制定了丹江水利枢纽供水调度图。采用设计水文系列对所提出调度图及供水调度方式进行校核,研究结果表明:该调度图具有物理机制明确、易于操作等优点,按该调度图运行可满足丹江口各供水对象用水需求,且南水北调中线调水过程更加均匀,研究成果可为丹江口水利枢纽供水调度提供指导和借鉴。

[Abstract]
The method of water-supply scheduling is an important issue concerning producing more benefits from the Danjiangkou hydro project. In this paper, a graph of water-supply scheduling was proposed for efficient utilization of water resources, based on the planning & design achievements of the Phase-I South-to-North Water Transfer Middle-Route Project and the requirements on water scheduling scheme compilation for the Middle Route Project. Meanwhile, designed hydrological inflows were used to check the proposed scheduling graph. Results showed that the graph is clear and easy to operate. The operation of Danjiangkou hydro project based on this graph can satisfy the designed water demand of all users and make the water transfer process more balanced. The scheduling graph can guide the operation of Danjiangkou hydro project.
