Abstract: A flow power plant comprises a rotor rotating about a rotation axis and having a plurality of pivoting blades. Each pivoting blade is mounted to the rotor for pivoting between a position pivoted-in towards and a position pivoted-out away from the rotation axis. One separate electric machine operable both as a motor and as a generator is assigned to each pivoting blade for applying torques between the rotor and the pivoting blade. A controller separately controls the separate electric machines during each revolution of the respective pivoting blade together with the rotor around the rotation axis in such a way that a predetermined course of a pivot angle of the respective pivoting blade results between the pivoted-in position and the pivoted-out position. The predetermined course of the pivot angle is predetermined for a maximum recovery of energy from a flow flowing against the rotor transversely to the rotation axis.

The system includes a power converter that converts rotational inertia by the turbine generator into direct current (DC) power responsive to the turbine generator operating in the coast down mode.
