Abstract:
1. Wind power plant, especially a wind power plant with a horizontal axis, having a rotor ( 20 ) which can rotate about a rotor axis which is preferably horizontal and at least one rotor blade ( 30 ), preferably extending approximately perpendicular to the rotor axis, an adjusting means to adjust the at least one, and preferably each, rotor blade by means of which adjustment the torque generated at the rotor axis by the wind load is adjustable, and a stabilizing system with which the rotor ( 20 ) can be stabilized in at least one specified, particularly low-load rotational position (park position), characterized in that the stabilizing system has a coupling means, especially a control means, which can be coupled to the adjustment means, with which, in case of deviation from the specified rotational position, especially in case of rotation of the rotor ( 20 ) out of the specified rotational position, adjustment of the at least one rotor blade ( 30 ) can be initiated to generate a torque counteracting this deviation or rotation.
