基于云河地球平台的数字孪生小浪底水利枢纽工程防汛调度系统建设

Construction of digital twin flfl ood control and dispatching system of Xiaolangdiwater conservancy project based on Yunhe Earth platform

摘要:

小浪底水利枢纽作为水利部数字孪生水利建设的首批试点工程，建设好数字孪生小浪底水利枢纽工程意义重大。以具有自主知识产权的云河地球数字孪生平台为建设载体，研究数字孪生小浪底水利工程数据底板构建、水利专业模型融合、可视化模型三维可视化表达等关键技术。聚焦小浪底水利枢纽防汛调度业务，在充分需求分析、完善原型设计基础上，研发数字孪生小浪底水利工程防汛调度业务平台，将小浪底水利工程雨水情监测、汛期调水调沙、库区淹没分析等“四预”业务在云河地球数字孪生平台进行三维可视化表达，在实际应用中能够对小浪底水利枢纽真实情况高仿真模拟，取得良好的应用效果。

Abstract:

As the Ministry of Water Resources digital twin water conservancy construction of the fi rst batch of pilot

projects，the construction of the digital twin Xiaolangdi water conservancy project is of great signifi cance. This paper

applies Yunhe Earth digital twin platform with its independent intellectual property. Key technologies such as the

development of data base，integration of professional hydraulic models，and three-dimensional visualization models

are explored. Digital twin Xiaolangdi water conservancy project fl ood control and dispatching business platform is

developed based on suffi cient demand analysis and improved prototype design，which focuses on the fl ood control and

dispatching business of the Xiaolangdi water conservancy project. The“ four pre” businesses of the Xiaolangdi water

conservancy project can be visualized，such as rainfall monitoring，discharge and sand regulation during flooding

seasons，and reservoir inundation analysis. In practical uses，it can simulate the real situation of Xiaolangdi water

conservancy project with high accuracy and achieve good performance.
