数字孪生在南水北调中线高质量发展中的应用实践

Application and practice of digital twins in high quality development of the middle route of the South-to-North Water Diversion Project

数字孪生以数字映射、虚实同步、模拟仿真、优化闭环等特性对物理空间对象进行不确定性预测以规避应急事件带来的风险,为工程建设管理提供了一种新的管控模式。南水北调工程是国家水网的主骨架和大动脉,为提升南水北调中线工程安全、供水安全、水质安全保障能力,解决运行管理中汛期交叉断面的防洪问题、水质突发污染事件的应急处置、不同时空尺度输水调度安全以及重要控制建筑物的结构安全等难题,南水北调集团中线公司积极探索数字孪生技术的应用,通过数据治理搭建数据底板,以历史场景库、预报调度规则库、业务规则知识库建立知识平台,以水利机理模型和深度学习技术建立多场景模型平台,构建了南水北调中线数字孪生平台,提升中线程的智能化水平,确保“三个安全”的工作目标实现和高质量发展,为水利行业提供经验和借鉴。

Taking use of digital mapping,virtual real synchronization,simulation,and optimized closed-loop,digital twins predict the uncertainty of physical spatial objects to avoid the risks brought by emergency events,providing a new control mode for engineering construction management.The South-to-North Water Diversion Project is the main backbone of the national water network.In order to enhance the engineering safety,water supply safety,and water quality assurance capabilities of the Project,solve the problems of flood control at flood season intersections,difficulties in operation and managements uch as emergency response to sudden water pollution events,safety of water transportation scheduling at different time and space scales,and structural safety of important control buildings,China South-to-North Water Diversion Middle Route Corporation Limited actively explores the application of digital twins technology.It has built a data base through data governance,established a knowledge platform based on historical scenario library,forecast scheduling rule base,and business rule knowledge base,constructed a multi-scenario model platform based on water conservancy mechanism model and deep learning technology,and established a digital twin platform for the middle route of the South-to-North Water Diversion Project,achieved an intelligent middle route,which ensures the realization of the work goals of“three safety”and high-quality development,and provides experience and references for the water conservancy industry.
