三峡为中心的长江防洪系统实时优化调度模型研究

主要介绍以三峡为中心的长江防洪系统联合调度运行的数学模型--洪水模拟模型和水库优化调度模型.前者包括水文学洪水演进模型,一维非恒定流模型,一维和二维组合洪水模拟模型,荆江分洪区与洪湖分洪区联合运用模型,用于反映洪水在河湖中的运动及防洪措施蓄泄效果;后者由总体控制模型与模糊决策,大系统解耦以及网络分析等模型组成,用于确定使库群起到最佳防洪效果的优化调度策略.

Real-Time Optimal Operation Models for the Three-Gorge-Reservoir-Centered Yangtze River Flood Control System

This paper provides a general review on mathematical models of optimal operation for the Three-Gorge-Reservoir-centered Yangtze River flood control system, divided into two parts—one dealing with flood routing simulation models and the other with optimal joint operational models for the reservoirs. The former including a hydrologic routing model, an 1-D unsteady flow model (from Yichang to Wuhan), an 1-D and 2-D hybrid unsteady flow model, and a 2-D rounting model for flood-divisions and flood-plains, is used to simulate dynamic processes of flood routing and effects of flood mitigation measures in the system, the latter consisting of an overall-control models and models of Fuzzy decision-making, large-scale system decoupling and network flows, is applied to determine optimal operational strategies for the reservoirs, to gain maximum flood control benefits.
