摘要
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。
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.
