水利枢纽群安全调控技术体系

Safety regulation technology system for water control projects

鉴于我国在主要流域已建成的特大水利枢纽群的运行过程受自然环境、工程结构、调度措施等诸多不确定因素的影响,以水利枢纽安全运行约束下的效益发挥为切入点,强调了梯级水利枢纽形成特大规模水利枢纽群后联合调度产生的风险与机遇。通过对比国内外水利水电工程相关研究成果,提出开展特大水利枢纽群联合调控与安全运行科学研究的必要性,综述了枢纽群安全风险辨识机理、枢纽群联合运行机理及多目标效益协调机理等研究进展,并提出水利枢纽安全调控技术体系框架,提出考虑防洪、发电、供水、通航、生态、航运等多维安全的水利枢纽群一体化调控技术发展方向。

Mega water control projects constructed in the main river basins in China can be influenced by a lot of uncertainties,such as natural environments,engineering structures and scheduling measures during operation. The benefit of water control projects under the constraint of safety operation is taken as the starting point,risks and opportunities originated from the joint regulation and control of the mega projects made up of cascade water control projects are emphasized. Related research results of water conservancy and hydropower engineering from both home and aboard are compared and the need for scientific research on joint control and safe operation of mega water control projects is proposed.Advances in the mechanisms of safety risk identification,joint operation and multi-objective benefit optimization of mega water control projects are reviewed,based on which a framework for regulation technology systems of mega water control projects is proposed. This paper gives the development direction of the integrated regulation and control technology for mega water control projects considering flood control,power generation,water supply,navigation,ecology,and shipping with multi-dimensional safety.
