FIELD: power engineering. SUBSTANCE: electric power station has following main components: dam, water head delivery pipeline, impulse hydraulic turbine, reaction hydraulic turbine, and electric current generator. Reaction hydraulic turbine has outlet pipe unions made over arches of circumference and diffuser to which pipe unions are connected over tangential line. Electric power station is provided with cylinder-type gate valve for regulation of water flow delivered to reaction turbine. Outlet pipe unions of reaction turbine are embraced by blades of impulse turbine which is connected with cylinder-type gate valve by rope with counterweight. Station increases efficiency of turbine and ensures constant rotation speed of turbine at changing water flow rate and eliminates loss of power at changing water flow velocity. EFFECT: higher efficiency. 5 dwg, 1 ex
