Flood control dispatching method based on digital twin

Abstract

The invention discloses a flood control scheduling method based on digital twin and the method comprises the following steps: S1, constructing a digital twin body of a flood control scheduling system; S2, tracking and updating the digital twin body of the flood control dispatching system to obtain the real-time and synchronous digital twin body of the flood control dispatching system; and S3, based on the digital twin body of the real-time synchronous flood control scheduling system, carrying out meteorological and hydrological ensemble forecasting by using the meteorological model and the hydrological models, predicting the flood control scheduling process of the target reservoir in the next week, analyzing, studying and judging the flood control situation according to the prediction result, and providing an adjustment scheme of the current reservoir scheduling rule. The invention has the advantages that the defects that an existing flood control dispatching method cannot comprehensively reflect real-time information of flood control dispatching, the effective forecasting period of meteorological and hydrological forecasting is short and forecasting precision is not high are overcome, flood control dispatching process information can be accurately provided, flood control risks can be dynamically evaluated, and flood disaster defense work can be smoothly carried out.

Description

technical field [0001] The invention relates to the technical field of flood control scheduling, in particular to a flood control scheduling method based on digital twins. Background technique [0002] Flood is a water flow phenomenon caused by natural factors such as heavy rain, rapid melting of ice and snow, storm surge, etc. Affected by the monsoon climate and topography, flood disasters occur frequently in summer in my country, posing a serious threat to the natural environment and the development of the national economy. Therefore, it has always been the focus of scientific research in related fields to use the regulation and storage function and control ability of reservoirs to control and dispatch floods in a planned way. [0003] At present, the flood control dispatching of reservoirs is mainly divided into the following methods, one is the conventional dispatching method, and the other is the forecast dispatching method. The conventional dispatching method usually...

Problems solved by technology

However, there are also certain problems in forecast scheduling. On the one hand, in order to provide a stable initial boundary condition for the model, it is often necessary to carry out a long period of cyclic numerical integration calculations in meteorological and hydrological forecasting. In addition, the model usually requires a large number of Calculation is used to determine the optimal parameter scheme, which greatly
