Regulating the temperature regime of water in the lower pool of a hydroelectric station

Yagin, V. P. / Koren’kov, V. A.

Conclusions An analysis showed that the water intakes for selective withdrawal of water from a reservoir for water-supply purposes known from the scientific and technical literature cannot be used effectively for withdrawing a large quantity of water for hydrostation turbines, and the known intakes for selective withdrawal of a large quantity of water have substantial shortcomings and are in need of further design improvement. Simultaneously with this, the conclusions of the 1993 Divnogorsk conference that at present “it is impossible to freeze the Yenisei River within the Krasnoyarsk city limits” for a number of reasons is confirmed. However, under more favorable conditions than the Krasnoyarsk hydrostation, the selective withdrawal of water from a deepwater intake for hydrostation turbines, despite the high additional expenditures, can be justified and necessary. The proposed design of a floating intake of an electric power station has a number of advantages compared with the known floating intakes. In this case it recommended to direct the water that is withdrawn from the surface layer of the reservoir and passed only through one or two turbines to save expenditures to the bank part of the river, which promotes in the lower pool the formation of ice near the river banks and in its branches in the winter and their “warming” in the summer.
