| 摘 要： | 针对三峡梯级汛期防洪、航运和发电综合运用问题,提出了基于运行水位-入库流量-下泄流量边界的防洪调度方式,推求了下泄流量-通航保证率间映射关系以量化航运效益,进而建立了基于多目标优化调度的汛期综合运用模型;考虑不同的防洪、航运和发电优先次序,制定了6种不同的汛期综合运用方案,结合已有的设计方案和2009年优化方案,进行了长系列历史实测径流和典型设计频率洪水的调度模拟。结果表明,相比较于2009年优化方案,依次考虑下游防洪、航运调度和发电调度的综合运用方案,能够在确保上下游防洪安全的同时,将通航保证率从79.08%提高到83.42%,汛期梯级发电量从644.27亿k W·h提高到664.42亿k W·h。

| 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. |
