大型调水工程自动化运行控制数值仿真研究

大型跨流域调水工程可以实现水资源优化配置,而为了提高渠道的运行管理水平,对这种复杂庞大的供水系统,实行运行自动化控制十分必要。在前人研究的基础理论之上,结合渠道运行控制系统的基本结构,建立了可直接应用于不同运行方式的大型调水工程运行调度数值仿真模型,并把该模型运用到南水北调中线工程的运行调度仿真计算中。结果表明,所建立的渠道自动化运行数值仿真系统可较好地实现多种运行方式下的渠道运行调度仿真计算,各种运行方式下渠道的闸门开度及水位过渡过程都较为良好。

Study on numerical simulation of automatic operation control of largescale water transfers project

The large-scale inter-basin water transfer project can realize the optimal allocation of water resources.However,in order to improve the operation and management level of canal system,the automatic operation technique is necessary for this complex and hugeous watersupply system.On the basis of basal theories studied by former authors,combining basic structure of canal operation control system,the numerical simulation mode of large-scale water transfers project was established in the paper,which could be directly used in to operation dispatch simulation of different canal operation methods,and the mode was applied to the operation dispatch simulation calculation of the middle route of China south-to-north water transfers project.The simulation results showed that the canal automatic operation control numerical simulation system had been established,which could preferably realize the simulation calculation of canal operation dispatch under various canal operation methods,and the transition processes of gate opening and water level were relatively good under all canal operation methods.
