Abstract

There is provided a power generation plant for obtaining electrical power from a water flow. The power generation plant includes a revolving unit having a water turbine, a directly driven electrical generator having a coaxial configuration with a generator rotor and generator stator, a gondola housing having a housing part to form a cylindrical internal opening where the generator stator is situated, a support element for supporting the revolving unit which is situated coaxially and radially inside the cylindrical internal opening to bear the generator rotor, and a bearing configuration for the running of the support element in the cylindrical internal opening. The electric generator of the power generation plant is situated asymmetrically in relation to the longitudinal extension of the cylindrical internal opening in the gondola housing and is also displaced toward the support structure carrying the gondola housing.
