全链式自主可控的数字孪生浙东区域水网OA

To address the key challenges in the operation and dispatching of open and complex plain river networks,such as strong dependence on foreign commercial software,insufficient accuracy of empirical scheduling,and difficulties in multi-objective coordinated scheduling,this study investigated a full-chain digital twin water network with indigenous control and technological autonomy,considering the multi basin plain water network in Eastern Zhejiang region,complex water system structure,significant water diversion constraints in strong tidal estuaries,and diverse livelihood security needs of the Eastern Zhejiang Regional Water Network.Based on a physical water network and leveraging a full-stack information technology application innovation(ITAI)architecture spanning from underlying hardware to upper-level applications,this study established an end-to-end digital twin system covering data infrastructure,modeling platforms,business applications and other aspects.This study independently developed 16 specialized water network models,overcoming the technological barriers posed by foreign commercial hydraulic modeling software such as MIKE and HEC-RAS.This resulted in four core technologies:a coupled model for complex river network water resource dispatching,forecasting of water intake conditions in tide-influenced estuaries,water quality simulation in plain river networks,and health assessment model of water network hub projects.These capabilities enabled intelligent,full-process scheduling for forecasting,early warning,simulation,and contingency planning regarding water supply,water quality,and engineering safety.The research outcomes have played a crucial supporting role in major practical scenarios such as supporting the Hangzhou Asian Games,drought resistance and water supply security in eastern Zhejiang,and typhoon defense,providing a Zhejiang model for digital twin water network construction nationwide.
