Abstract: The present disclosure is directed to a lifting device for a rotor blade of a wind turbine. The lifting device includes at least one cradle and a vacuum sealing system configured with the cradle. The cradle has a profile that corresponds to at least one of the exterior surfaces of the rotor blade so as to support at least a portion of the rotor blade. The vacuum sealing system is configured to secure the rotor blade to the cradle as the rotor blade is lifted and/or lowered from a hub mounted atop a tower of the wind turbine.

Abstract: An electric power system for a wind turbine includes at least one auxiliary load bus configured to transmit electric power to auxiliary equipment. The auxiliary load bus is further configured to receive electric power having a voltage within a first predetermined tolerance range. The system also includes at least one motor-generator set coupled to the auxiliary load bus. The motor-generator set is configured to receive electric power having a voltage within a second predetermined tolerance range and transmit electric power to the auxiliary load bus in the first predetermined tolerance range.

Abstract: The present disclosure is directed to a system for controlling a yaw drive of a wind turbine when a native yaw drive control system is non-operational. The system includes an external sensor configured to detect a parameter indicative of a wind condition experienced by the wind turbine. The system also includes an external controller communicatively coupled to the external sensor. The external controller is configured to control the yaw drive based on measurement signals received from the external sensor. The external sensor and the external controller are electrically isolated from the native yaw drive control system.

Abstract: The present disclosure is directed to systems and methods for removing or installing a pitch bearing of a wind turbine. The method includes installing a first pulley block at an up-tower location of the wind turbine and configuring a second pulley block with the pitch bearing. A pulley cable is routed from a ground location over the first pulley block to the second pulley block such that the second pulley block is configured to slide along the pulley cable. The method also includes rotating the pitch bearing to a tilted position. Thus, the method further includes lowering or lifting the pitch bearing in the tilted position so as to prevent the pitch bearing from colliding with the tower.
