A wind-driven power plant is disclosed. It comprises at least one rotor which is mounted in a support structure to be rotatable about a rotor gyration axis. The rotor is also pivotable about an upstanding axis by means of an adjusting device for wind orientation. The rotor gyration axis is mounted in the support structure so as to be pivotable about another imaginary tilt axis in a manner permitting precession of the rotor. The tilt axis interacts both the rotor gyration axis and the upstanding axis at an angle. In addition to the adjusting device for turning the rotor about the upstanding axis to account for changes in the horizontal wind direction, the plant includes at least one setting device which exerts a torque on the rotor gyration axis or on the rotor having torque vector components perpendicular to the gyration axis and perpendicular to the upstanding axis. The magnitude of these components may be controlled by means of a control device in response to the rotor rotational speed and the desired wind direction orientation movement to the exerted on the rotor in accordance with the torque to be exerted by the adjusting device and in compliance with the laws of gycoscopic precession. |
