梯级水库群调控的水动力水质仿真模拟技术

Simulation techniques of hydrodynamic and water quality caused by regulation and operation in cascade reservoirs group

梯级水库群形成的巨系统的复杂性给运行管理和调控决策带来不确定性,保障水库群效益的发挥亟需先进的信息技术和水利专业模型提供支撑。以虚拟现实技术、模型计算和在线监测为基础,以水流水质的可视化表达为核心,系统分析虚拟现实技术与数值模拟的结合方式,研究梯级水库群调控虚拟环境建模方法、三维虚拟流域环境平台研发、模型和监测驱动的水动力水质虚拟仿真技术。初步以三峡工程为例,验证研发技术的可行性,为梯级水库群智能化管理和调度提供新的思路。

Complex giant system of cascade reservoirs formed by cascade reservoirs will bring great uncertainty totheir running management and control decision-making. In order to guarantee benefit development of reservoirs group,it is an urgent need to provide advanced information technology and water conservancy professional model as support.Based on the technology of virtual reality, model calculation and online monitoring, and taking the visual expressionof water quality and hydrodynamics as the core, the paper systematically analyzes the combination mode between thevirtual reality technology and numerical simulation. And then it presents the modeling method of virtual environmentfor cascade reservoirs group, 3D virtual watershed environment platform development and key techniques of virtualsimulation of water quality and flow characteristics driven by model and monitoring. The developed techniques arepreliminary application in the Three Gorges Project and proved to be feasible, which provides a new train of thought onintelligent management and dispatching of cascade reservoirs group.
