ABSTRACT:
The invention relates to a method for operating a wind power plant with a rotor and with at least two rotor blades rotatable about a common rotor axis in a rotor blade plane, whereof each can be swivelled about a swivel axis which is roughly parallel to its longitudinal axis approximately perpendicular to the rotor axis, in which the setting or pitch angels of the rotor blades are set with respect to the rotor blade plane as a function of the operating and in particular wind conditions, in which the pitch angels of at least two rotor blades in a parking position of the rotor, in which rotor rotation about the rotor axis is decelerated, are set to different values.
