FIELD: electricity.
SUBSTANCE: invention relates to hydropower industry, in particular, to devices for conversion of energy of flow of fluid medium into electric energy. Hydraulic power plant of conveyor type comprises guide channel 1, working element with flexible element in form of closed chain transmission consisting of interconnected links-carriages, with units of blades, each of which contains at least two symmetrical pairs of blades. Blades are made telescopically retractable and kinematically connected to mechanism of angle of attack variation. Guide channel 1 comprises main and two auxiliary channels with shutters at inlet arranged along main channel on both sides. Auxiliary channels are separated from the main channel by movable channel chutes with guide vanes. Hydroelectric power plant can be equipped with additional guide channels 1 with working elements with formation of cascade hydroelectric power plant 47.
EFFECT: invention is aimed at increasing capacity of a hydroelectric power plant.
