| 摘 要： | 对于温度成层型水库,水电站进水口分层取水方式通常被采用,目的是有选择地取用水库的不同层水体,减免下泄低温水对下游河流环境的负面影响。目前缺乏简单实用的分层取水下泄水温的预测公式。笔者针对糯扎渡水电站工程,试验模拟水库水温分布,量测下泄水温;依据大量的试验数据,建立下泄水温预测公式;所提出的公式得到了锦屏一级电站下泄水温试验数据的验证。

| Abstract: | In thermally stratified reservoir, a multi level intake structure is usually adopted in hydropower station to reduce the negative effect of releasing lower temperature water to the environment in downstream reach. And a simple and practical formula of water temperature released is need. In this paper, based on Nuozhadu Hydropower Station, a model test is conducted to model the thermal stratification of this reservoir, and measure the temperature of water released from the intake structure. A prediction formula of water temperature released is put forward based on the experimental data. The formula is validated by the experimental results of water temperature released from the intakes of Jinping No.1 Hydropower Station. |
