The aim of the invention is to create a hydroelectric power plant that is better and less expensive than previous embodiments. Said aim is achieved by a hydroelectric power plant which supports the formation of a stable gravitational vortex which tends to be formed also in the upper reaches directly in front of the turbine inlet of conventional river stations as a lost vortex and is therefore prevented as much as possible there. The inventive hydroelectric plant, however, ensures that the necessary current-related conditions are fulfilled for reinforcing the rotational movement of the water, which is created when the water flows off, in an unimpeded manner into a stable gravitational vortex without using pressure lines and directing devices. A turbine that rotates in a coaxial manner within the gravitational vortex and is impinged upon along the entire circumference thereof withdraws rotational energy from the gravitational vortex, which is converted into electric power in a generator. In addition, the inventive hydroelectric power plant allows the body of water that is used for generating power to be aerated so as to enhance the self-cleaning properties thereof and the water temperature to be reduced during the summer while decreasing the tendency thereof to be covered with ice during the winter and improving the water quality by activating the water. |
