中文摘要
2014年南水北调中线工程引水进京后,北京市将形成外调水、当地地表水和地下水多水源联合供水的格局。这为北京市的供水提供保障的同时也带来了很多的挑战。论文针对北京市多水源供水的核心区——多水源供水环路建立多水源联合调度模型,并研究了不同边界条件下的调度成本和水源组成。研究发现,建立的北京市多水源联合调度模型可以很好地满足不缺水不弃水的目标,只有考虑大宁水库防洪时才会发生弃水。提高南水北调来水和需水预报的准确度,可以有效减少密云水库的供水量和系统调度成本,同时减少双水源同时供水的时间。考虑大宁水库的防洪调度,会使密云水库供水量和系统调度成本增加,增加幅度较大。地下水的使用有利于减少密云水库的供水量和双水源同时供水的时间,但是会增加系统调度成本。密云水库的补偿供水功能和反向调蓄功能均可以有效的使用。南干渠沿线水厂和第九水厂受双水源同时供水时间较多,而其他水厂几乎没有双水源同时供水的现象。

ABSTRACT
As the Mid-route of South-to-North Water Transfer Project diverts water to Beijing in 2014, Beijing wil
l establish the water supply pattern which consists of diverted water, local surface water and ground water. It will guarantee the water supply of Beijing as well as create a lot of challenges. In this paper, joint operation model aimed at the multiple water sources operation cycle in Beijing is established and scheduling cost and water quality conditions under different edge conditions are discusd. Results prent that operation is highly reliable with no water shortage and little water dertion only by considering the flood control of Daning Rervoir. The increa of the forecast accuracy of South-to-North Water Transfer Project and water demand can reduce the water supply of Miyun Rervoir and system operation cost effectively. It can shorten the time of mixed water supply as well. Meanwhile, the total cost as well as the water supply of Miyun Rervoir will increa with a large margin when taking the flood control of Daning Rervoir into consideration. Making u of ground water will shorten the time of mixed water supply and reduce the quantity supplied by Miyun Rervoir at the expen of additional cost. Miyun Rervoir is doing well in water compensation as well as regulating water of South-to-North diversion project. The time the 9th waterworks and water plants near the south main canal receive mixed water supply is longer than that of other water plants.
Keywords:Joint operation model of multiple water sources; South-to-North Water Transfer Project; Beijing water supply cycle
