A low-pressure hydroelectric power station (1) for generating electrical energy has an inlet and acceleration channel (17, 20), a turbine chamber (22) with a centripetal turbine (3) and an intake connector (10). The acceleration channel (20), the turbine (3) and the turbine chamber (22) are dimensioned such that a continuous and maximum volume flow with a maximum flow velocity flows through the turbine. The water stream has a Froude number of approximately 1. The turbine (3) has a flat and wide design. The turbine (3) is situated at a height (hu) above a downstream water level (27) that is in a range from 25 to 50% of the total drop (Hf) of the water. The power station according to the invention allows an economical construction and a fish-friendly operation. |
