【摘要】：南水北调中线工程具有输水线路长、涉及区域广、参与工程多、调水规模大、输水工况多变等特点,给工程的调度、控制和运行管理带来极大困难。工程上技术的难题在于其背后的科学机理性问题并没有完全揭示和解决,包括变化条件下多水源联合多维均衡调控机制、水量水质多过程耦合机理、多物质突发水污染应急调度模式、多闸门联合运用下的明渠水力学响应机理与控制等。为建立一套完备的技术体系来支撑其调度运行,围绕"预报-调度-模拟-控制-评价"这五个关键环节对现有研究进行分类总结;然后,在综述以往研究不足的基础上,对亟需攻关的关键技术进行了详细阐释,涵盖了水源区与受水区预报调度、总干渠冰水污染多相模拟、总干渠水量水质联合调度、中线全线自动化控制技术、调度评价技术与平台建设等多个方面;最后,文章讨论了实现中线智能调控和应急调度亟待解决的科学问题,并进行了研究总结。
[Abstract]:The middle route project of South-to-North Water transfer Project has the characteristics of long transmission line, wide area involved, more participation in the project, large scale of water transfer, changeable condition of water conveyance, and so on, which brings great difficulties to the dispatching, control and operation management of the project.The problem of engineering technology lies in the fact that the scientific mechanism behind it has not been completely revealed and solved, including the mechanism of multi-source combined multi-dimensional equilibrium control under changing conditions, the coupling mechanism of water quantity and water quality, and the mechanism of multi-process coupling of water quantity and water quality.Multi-material sudden water pollution emergency dispatching mode, hydraulic response mechanism and control of open channel under the combined use of multi-gate.In order to establish a complete technical system to support its scheduling operation, the existing research is classified and summarized around the five key links of "forecast, scheduling, simulation, control and evaluation".The key technologies urgently needed to be solved are explained in detail, including forecasting and dispatching of water source area and water receiving area, multiphase simulation of ice water pollution in total trunk canal, combined operation of water quantity and water quality of total trunk canal, automation control technology of the whole line in the middle line.Finally, this paper discusses the scientific problems that need to be solved to realize the intelligent control and emergency dispatch in the middle line, and makes a summary of the research.
