Abstract

Given the observations at the section of the Ob river below the dam location of the Novosibirsk Hydropower Station, the calculations of water level dependence on water discharge and ice hole length in winter are carried out by the model of nonstationary hydrodynamic and ice-thermal processes. Some algorithm is developed that uses the dependence and allows us to determine the optimum discharge at the dam section providing the stable functioning of the river water intakes near Novosibirsk. The results of calculations are given for various values of the roughness coefficient of the lower ice cover.

水力发电站下水池水力和热力过程的综合数学模型

摘要

根据新西伯利亚水电站坝址以下鄂毕河段的观测资料，冬季的水位依赖于排水量和冰孔长度的计算是通过非平稳的水动力和冰热过程模型进行的。开发了一些算法，该算法使用了相关性，并允许我们确定坝段的最佳流量，从而使新西伯利亚附近的河道取水口稳定运行。给出了下冰盖粗糙度系数的各种值的计算结果。
