流域水循环调控水动力水质仿真模拟技术

梯级水库群形成的复杂巨系统的复杂性给运行管理和调控决策带来了不确定性,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来提供支撑。本文以虚拟现实技术、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,系统分析了虚拟现实技术与数值模拟结合方式,研究了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了新的思路。

The Techniques of Simulation of Hydrodynamic and Water Quality Caused by Regulation and Operation in River Basin

Complex giant system formed by cascade reservoirs will bring great uncertainty to their running management and control decision-making.in order to guarantee fruitfully economic profit of cascade reservoirs; it is in urgent need of advanced information technology and water conservancy professional model to support. Based on virtual reality technology, the model calculation and data from online monitoring and taking the visual expression of water quality and hydrodynamic as the core, the paper systematically analyzes the combination mode between the virtual reality technology combined and numerical simulation method. And then it presents the modeling method of virtual environment for cascade reservoirs, 3D virtual watershed environment platform development and key techniques of virtual simulation of water quality and flow characteristics driven by model and monitoring. The developed techniques are preliminary application in the Three Gorges Project and proved to be themselves feasibility, which provides a new train of thought on intelligent management and dispatching of cascade reservoirs.
