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.
