建设数字孪生工程 赋能流域综合治理——以数字孪生太浦闸建设实践与探索为例

Construction of digital twin water projects enables the comprehensive management of basins:a case study of the construction and exploration of digital twin project in Taipu sluice

太浦闸是太湖东部骨干泄洪及环太湖大堤重要口门控制建筑物,防洪和供水效益突出,工程的控制运行要求很高。苏州管理局积极探索数字孪生水闸工程建设先行先试的道路,在太浦闸原有的基于机器学习的水位流量关系模型上融入“四预”要求,进一步实现了泄流预测、准确判断流量变化趋势等功能,并通过搭建调度运行、安全运行等“四预”应用场景,实现了太浦闸在不同调度指令下基于孪生场景的全流程动态监控和模拟,以及模型驱动下的工程运行安全隐患快速分析预警,帮助该工程在服务太湖流域、长三角一体化示范区防洪、供水、水生态环境方面进一步发挥重要作用。

Taipu sluice is the key control building for flood discharge in the east of the Taihu Lake and the important entrance of the levee around the Taihu Lake.It has outstanding flood control and water supply benefits,and the project has high requirements for control and operation.Suzhou Administration Bureau actively explored the first trial of the construction of the digital twin sluice project,incorporated the“requirements for the forecasting,warnings,drills and prevention plans”into the original water level and flow relationship model based on machine learning of the Taipu sluice,further realized discharge prediction and accurate judgment of flow change trend,and built the application scenarios of“forecasting,warnings,drills and prevention plans”such as regulation operation and safe operation.This achieves the whole-process dynamic monitoring and simulation of Taipu sluice based on twin scenarios under different regulation instructions as well as the rapid analysis and early warning of potential safety hazards in project operation driven by the model,promotes the project s function in flood control,water supply and water eco-environment in the Taihu Lake Basin and Yangtze River Delta Integrated Demonstration Area.
