国外大型调水工程渠道运行控制综述

Channel Operation Control of Overseas Inter-basin Water Transfers Projects

与常规的以经验为主的运行方式相比,考虑了水动力学影响、以多渠池串联的整个渠道系统为研究对象的渠道运行控制在增加调水工程的安全性、降低运行成本、提高输水效率等方面能取得更佳的效果。国外关于调水工程渠道控制的研究起步较早,基于非线性偏微分圣维南方程组发展了多种离散化、线性化等简化方法,建立了相应的控制模型,并从不同角度确定了其控制方法以及控制算法。参考已有的研究思路和方法,总结国外渠道运行控制的成果,对我国南水北调工程的运行控制有着重要的借鉴意义。

Compared with conventional approaches, the channel control with consideration of hydrodynamic effects in the multi-pool channel system achieved better results in increasing operating safety, reducing operating costs, improving efficiency, and other aspects of inter-basin water transfers projects. Studies abroad in this field started earlier. Various ways of discretization and linearization and such simplified methods were developed to solve the non-linear partial differential Saint Venant equations. The relevant control models were also established,as well as the control methods.control algorithms from different point of views. Based on the existing research, a summing-up of the production on channels control played an important role in the reference for operation of South-to-North Water Transfer Project in China.
