摘要
为了满足下游河道的生态需求,在电站进水塔前缘设置斜置的导水叠梁,通过调节导水叠梁的设置高度,使机组引用水尽量取自水库表层,保证引用水有足够的温度及含氧量。介绍了巴贡(BAKUN)进水口水力学模型及试验情况,分析了进水口前池的水流流速分布、水流流态,确定了导水叠梁的设置高度,并结合试验对不同工程设置导水叠梁的必要性进行了分析。
To meet ecologic demand in the downstream channel, the tower-shaped chamber is set in front of the bellmouth intake, and the inclined training stoplogs are installed at the leading edge of the intake tower, it can take water from the surface of the reservoir for unit generation by regulating height of training stoplogs, in order to guarantee the water through units to have proper temperature and oxygen content. It presents the hydraulic model and test conditions of the intake for Bakun Hydropower Project, analyzes flow velocity distribution and flow condition in the forebay of the intake, determines the height of training stoplogs, and finally analyzes necessity of setting training stoplogs in accordance with tests for different projects.
