考虑水流演进规律的引大济湟工程水量调度研究

Study on water quantity operation of Datong-to-Huangshui River Water Diversion Project considering flow routing law

针对引大济湟工程供水调度范围广、水利设施多样以及工程调度目标复杂等难点,提出考虑水流演进过程的大系统分解协调技术,构建引大济湟工程水量调度模型。该模型基于大系统协调分解理论将引大济湟工程划分为多个子系统,利用子系统间的水力联系构建协同机制,获取各项水利设施调度方案信息,并结合一维水动力模型获取各个节点断面的水位、流量关键信息。结果表明:相比于仅通过水量分配模型获取的调度方案,采用该模型得到的方案不仅可满足供水需求,还可实现对供水过程的动态跟踪、模拟仿真,为用户提供更为精准、科学的供水调度方案编制手段,进一步确保沿线供水安全。

Aiming at the difficulties such as wide range of water supply operation,diversified water conservancy facilities and complex engineering operation objectives of Datong-to-Huangshui River Water Diversion Project,a decomposition and coordination technology of large-scale system considering the flow routing process was proposed,and a water quantity operation model for this project was constructed.Based on the coordination decomposition theory of large-scale system,the whole system of Datong-to-Huangshui River Water Diversion Project was divided into multiple subsystems,and a coordination mechanism was constructed by the hydraulic connection between the subsystems to obtain the operation scheme information of various water conservancy facilities.Combined with the one-dimensional hydrodynamic model,the key information of water level and flow of each node and section was captured.The results show that compared with the operation scheme obtained by the water allocation model,the scheme obtained by this model can not only meet the water supply demand,but also realize the dynamic tracking and simulation of the water supply process.The model can provide users with more accurate and scientific methods for preparing the water supply operation plans,and further ensure the safety of water supply along the line.
