Evaluation and prediction method for stratified water taking effect of stoplog gate
The invention relates to the technical field of water conservancy and hydropower engineering, and provides a stoplog gate layered water taking effect evaluation and prediction method in order to conveniently evaluate and predict a stoplog gate layered water taking effect. The measured data of the discharged water temperature after the stop log gate is started is compared with the measured data of the discharged water temperature without the stop log gate at the same time, and the layered water taking effect of the stop log gate is represented by the average temperature difference of the water temperature of the tail water with the stop log gate and the water temperature of the tail water without the stop log gate, so that the influence of system errors is eliminated, and the measured layered water taking effect of the stop log gate is more accurate. During prediction, a relation formula between related data and the water taking effect is obtained by adopting a multiple regression analysis method, the operation is simple and convenient, the practicability is high, and the method can be applied to actual engineering operation.
本发明涉及水利水电工程技术领域，为了便于对叠梁门分层取水效果进行评估及预测，提供了一种叠梁门分层取水效果评估及预测方法，采取“有无对比”的方法，将启用叠梁门后的下泄水温实测数据与同时刻无叠梁门的下泄水温实测数据进行对比，并以有叠梁门尾水水温和无叠梁门尾水水温平均温差来表征叠梁门分层取水效果，消除了系统误差的影响，测得的叠梁门分层取水效果更为准确。在进行预测时采用多元回归分析法获取相关数据与取水效果间的关系公式，操作简便，可实施性强，可应用于工程实际运行。
