城市防洪“四预”智能调度系统建设与应用

Construction and application of“Four Pre”intelligent dispatching system for urban flood control

围绕太湖流域平原河网城市防洪“四预”智能调度系统建设,从算据、算法、算力、“四预”业务和信息融合共享等方面剖析了传统防汛信息化系统存在的问题,结合无锡大包围水工程智能调度系统实践,从多源数据资源集成汇聚、精细化河网模型构建和知识模型算法深度融合等方面提出了建设措施与技术途径,将滚动预报和调度预演作为核心关键技术,构建了“监测预报-动态预警-场景预演-调度预案”的防洪“四预”业务应用体系,全力打造水工程预报调度一体化防汛模式,对于加快太湖流域数字孪生水网工程和智慧水利建设具有重要的指导意义。

Focusing on the construction of the“Four Pre”intelligent dispatching system for urban flood control in the plain river network of Taihu Lake basin, the paper analyzes the problems existing in the traditional flood control information system from the aspects of data, algorithms, computing power,“Four Pre”and information fusion.Combined with the practice of the intelligent dispatching system of the Wuxi water reclamation project, the construction measures and technical approaches are proposed from the aspects of multi-source data resource integration and aggregation, refined river network model construction and deep integration of knowledge model algorithms. With rolling forecast and scheduling rehearsal are taken as the core key technologies, the flood control“Four Pre”business application system of‘monitoring and forecasting-dynamic early warning-scenario rehearsalscheduling plan’is built. Efforts are made to build an integrated flood control model for water project forecasting and scheduling. It is of great guiding significance to accelerate the digital twin water network project and intelligent water conservancy construction in the Taihu Lake basin.
