摘要
以去学水电站为例,在充分考虑流量、流速、气温、辐射等影响因素基础上,采用一维垂向水量水温耦合模型模拟预测水库垂向水温分布规律。结果发现:下泄水温变化规律基本与水库自然水温变化规律相近;水库水温垂向分层年内变化显著,年际变化不明显,并具有明显的滞后效应。
For example as the Quxue power station,this paper uses one-dimensional vertical water yield and temperature coupled model to simulate and predict vertical distribution of water temperature in the reservoir dam site,based on a full consideration of the flow, flow rate, temperature, radiation and other factors. The results show that the change laws of discharged water temperature are similar to the natural temperature in the dam site, water temperature in the reservoir changes significantly during the year, but did not changes significantly among different years, and with a significant lag effect.
