Experience of using the turbine-generator units of the Kolyma hydroelectric station for idle discharge of water

Abstract

Diagonal-flow turbines with the following technical characteristics have been installed at the Kolyma hydroelectric station: turbine capacity 184 MW; nominal rotational speed 214.3 min-1; maximum head i16 m; minimum operating head 94.6 m; start-up head 40 m; runner diameter 4200 mm. The units of the Kolyma hydrostation have an umbrella layout with support on the turbine cover with three guide bearings, one of which is combined with a thrust bearing.
