Patent ID: 7393180

Claim:
A wind power plant comprising: at least two rotor blades rotatable about a common rotor axis in a rotor blade plane; a drive mechanism for setting the pitch angles of the rotor blades with respect to the rotor blade plane; and a control device operable for controlling the drive mechanism, wherein the drive mechanism is controllable for setting different pitch angles for at least two rotor blades, wherein the control device is operable to swivel a first rotor blade about a swivel axis running approximately parallel to its longitudinal axis that is approximately perpendicular to the rotor axis to set the first rotor blade at a first pitch angle with respect to the rotor blade plane, to swivel a second rotor blade about the swivel axis to set the second rotor blade to a second pitch angle that is different than the first pitch angle, and to swivel a third rotor blade about the swivel axis to set the third rotor blade to a third pitch angle that is different than the first and second pitch angles.
