为充分发挥跨流域引水与区域水资源效益,城市供水水库群的联合调度成为水资源优化配置的关键。本文以深圳市西部城市供水系统的铁岗—石岩水库群为例,针对水库群供水＂多对一＂关系和水库群联合供水调度,建立水库群联合供水调度模型。本文首先针对＂多对一＂关系,分别采用主供水库添加联合调度线和构造＂聚合水库＂的方式建立供水调度模型;在石岩和铁岗水库调度图中分别设置提水线和提水限制线;然后将石岩—铁岗水库共同承担的供水任务分为4种供水方案,并采用模拟-优化的方式对水库群的调度规则进行求解。最后对各方案的调度效益进行对比与评价。

英文摘要：

To maximize the benefits of water diversion and regional water resources, reservoir joint operation has become a key method for improving system efficiency. This paper describes a case study of the Tiegang-Shiyan multi-reservoirs in the water diversion and supply system for the west of Shenzhen. First, we analyzed the operation policies for common water users（i.e. several reservoirs supply water to the same users） and the pumping station of the system. The operation policies for common water users were formulated based on two methods. One adds an operation line on the operation chart of the main supply reservoir; the other constructs an equivalent aggregated reservoir by which the operation policies are worked out. The operation policies for the pumping station were formulated by setting a pumping line and a limit line on the operation chart of the multi-reservoirs. Then, the total volume of water supply by the multi-reservoirs to common water users was examined using four schemes. For each of the schemes, a progressive optimality algorithm（POA） was used to optimize its parameters of operation policies. Finally, using the operation policies already determined, we simulated the water supply and diversion operation in the four schemes, and evaluated and compared their efficiencies and benefits.
