摘要： 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.

摘要： Method of operating a wind turbine comprising a plurality of blades rotatable along their longitudinal axes using a pitch mechanism, and comprising one or more movable trailing edge surfaces. The method includes predicting, at a first moment in time, a high load for one or more of the blades at a second moment in time. The method further comprises actuating on one or more of the movable trailing edge surfaces of these blades such that the trailing edge surfaces have a wider range of control to counteract the predicted high loads before the second moment in time, and simultaneously pitching the blades such as not to negatively affect the operation of the wind turbine. The method furthermore comprises, at the second moment in time, actuating the one or more movable trailing edge surfaces of the at least one or more blades to counteract the high loads.

摘要： The present subject matter is directed to a system and method for improving speed control of a pitch drive system of a wind turbine. In one embodiment, the pitch drive system includes a direct current (DC) motor having an armature and a series-field winding, a battery assembly having a positive terminal and a negative terminal, and a current-controlling device configured in series between the positive terminal of the battery assembly and the series-field winding. The battery assembly is configured to supply power to the pitch drive system and the current-controlling device is configured to supply current to the series-field winding so as to ensure a field flux does not equal zero. Thus, the current-controlling device has the effect of limiting the maximum speed of the DC motor.
