面向航运和发电的三峡梯级汛期综合运用
Integrated utilization of the Three Gorges Cascade for navigation and power generation in flood season
摘要
Abstract
The Three Gorges Cascade undertakes the tasks of flood control,navigation and power generation,while they often conflict with each other in flood season.In order to solve the problem,this paper presents a flood control mode with water level-inflow-outflow boundary,and drafts the relationship between outflow and navigation rate for quantifying navigation benefit.On this basis,an integrated utilization model of multi-objective optimal operation in flood season is proposed.According to the priorities of different objectives,6 schemes of integrated utilization in flood season are drafted.With design scheme and 2009 optimal scheme,these integrated schemes are applied to the simulation in historical inflows and design floods for verifying their effectiveness.The results show that the integrated scheme which considers downstream flood control,navigation,power generation in turn has better performance when compared to 2009 optimal scheme.The navigation rate is enhanced to 83.42 ％ from 79.08 ％,the total power generation is increased to 664.42 from 644.27 billion kWh,while upstream safety and downstream safety of flood control are both ensured.关键词
