FIELD: machine building.;SUBSTANCE: invention relates to power engineering and is designed to transform the power of river streams and tides into AC or DC electric power. The damless hydroelectric power station comprises a confuser-diffuser cylindrical-entrance water duct whereat a quick-acting gate and turbine are located. The said gate is arranged in the turbine and represents a double-acting facility operating depending upon the water flow direction in the aforesaid water duct. The said cylindrical entrance communicates via bypass branch pipes with check valves fitted therein with two buffering capacities communicating via a bypass pipeline. The pipeline houses the turbine connected to the electric generator. Each buffering capacity communicates with the aforesaid cylindrical entrance with the help of two bypass branch pipes, one being located ahead of the gate while the other one operates behind it along the stream in water duct.;EFFECT: all-season acting damless hydroelectric power station.;1 dwg
