Abstract：The simulation rehearsal of water delivery scheduling in the middle route of the South-to-North Water Diversion Project serves as the foundation for precise dispatching decisions.Addressing the scheduling challenges of the middle route,such as the long water transmission line,numerous control gates,and complex operating conditions,a digital twin South-to-North Water Diversion Middle Route water delivery scheduling simulation preview platform has been developed.This platform includes intelligent data cleaning models,self-learning training models,accurate simulation models for one-dimensional constant flow and unsteady flow in the main canal,and simplified three-dimensional hydraulic simulation models for typical buildings.It achieves precise simulation of the hydraulic control scheme's effectiveness under any specified operating conditions,forming effective dispatching plans.The preview platform exhibits strong flexibility and universality,allowing users to simulate various operating conditions at different spatial and temporal scales and adapt to changes in boundary conditions such as inflow and outflow.The system possesses self-learning capabilities,continuously enhancing calculation model parameters and structure with the accumulation of monitoring data,thus improving calculation accuracy.The system provides strong technical support for safe and efficient water delivery scheduling.
