摘要
以深圳抽水蓄能电站上库为例,根据物理模型提供的边界条件,建立了一种进出水口模型试验和直角二维数学模型的混交模型.采用发电工况试验数据对建立的混交模型进行验证,模拟了抽水工况和发电工况运行下死水位、1/2工作水位和正常蓄水位对应的库盆流态.模拟结果表明,在抽水工况运行下受地形影响,库盆和进出水口附近会产生环流区,两种工况下库盆水流流速与库水位成反比关系.该模型对同类抽水蓄能电站进出水口的设计与研究提供了参考.
A mixed model is established to simulate reservoir flow pattern of the upper reservoir of Shenzhen pumped-storage power station,in which a 2-D right-angle mathematical model is applied to simulate the reservoir flow pattern,and the results of an inlet / outlet model test supply the mathematical model with calculating conditions.The model is verified by test data at the condition of power generation.The reservoir flow pattern at dead water level,one-half of the work of the water level and normal water level are respectively simulated in the condition of pumping and power generation.The results indicate that for topographical reasons circulation flow area can be found in the reservoir and near the inlet / outlet in the condition of pumping,and that the flow velocity is inversely related to the reservoir level in both conditions.This model provides scientific reference for design and research of inlet / outlet in similar pumped-storage power stations.
