摘要： The present patent application concerns wind turbine (100) having a rotor with a first rotor blade (140) and a pitch control system (200) with a first drive system (210) for adjusting a pitch angle of the first rotor blade, wherein the first drive system (210) is adapted to transform rotational energy of the rotor blade rotating about its longitudinal axis into another form of energy such that a counter torque against the rotating direction is induced. Further, the present patent application concerns a method for controlling a pitch velocity of a rotor blade of a wind turbine, the wind turbine comprising at least one drive system for adjusting a pitch angle of said rotor blade, the drive system being adapted to operate in a active mode, wherein the drive system rotates the rotor blade, and in a passive mode, wherein the drive system exerts a counter force against the rotating direction, when the rotor blade being rotated by another force than the force of the drive system, wherein the pitch velocity is controlled by operating the drive system in said passive mode when the pitch of the rotor blade is changed from a first position to a second position.
