A system and method reduce vibrations in a blade mounted on a hub of a wind turbine rotor mounted atop a tower when the rotor is in a stand-still and limited yaw capacity state due to one or more cables that extend between a turbine-mounted crane and ground-based equipment. The method determines a new yaw position for the rotor that will reduce actual or predicted vibrations in the blade; and with a wind turbine controller in communication with the yaw system and a crane controller, the rotor is yawed from an initial yaw position to the new yaw position while simultaneously controlling payout of the cables from the ground-based equipment so that the cables wrap at least partially around the tower as the rotor rotates relative to the tower to the new yaw position.
Resumen de: WO2026043489A1
A system and method reduce vibrations in a blade mounted on a hub of a wind turbine rotor when the rotor is in a limited yaw capacity state with a defined allowable yaw sweep. An allowable yaw sweep is defined for the limited yaw capacity of the rotor. With a sensor in communication with a controller, actual vibrations in the blade are monitored with the rotor at an initial yaw position. Upon detection of vibrations in the blade, the controller determines a first new yaw position within the allowable yaw sweep and issues a yaw command to a yaw system to yaw the rotor to the first new yaw position. At the first new yaw position, the method and system continue to monitor for actual vibrations in the blade.
Resumen de: WO2026043488A1
A system and method reduce vibrations in a blade mounted on a hub of a wind turbine rotor when the rotor is in a limited yaw capacity state with a defined allowable yaw sweep. The direction of an incoming wind acting on the blade is determined and used to define a blade angle of attack between the wind direction and a chord of the blade. If the blade angle of attack is at a critical angle of attack known to induce vibrations in the blade, a controller issues a yaw command to a yaw system to yaw the rotor to a new yaw position within the allowable yaw sweep where the blade angle of attack is not at the critical angle of attack.
Resumen de: WO2026043486A1
A system and method reduce vibrations in a blade on a hub of a wind turbine rotor when the rotor is in a non-operational and limited yaw capacity state. A yaw sweep is defined for the limited yaw capacity state. A controller determines a first yaw command to align the rotor into the wind and within a first range relative to the wind direction, the first range defining a forward zone of reduced or no blade vibrations caused by the incoming wind. When the first yaw command exceeds the yaw sweep, the controller determines a second yaw command that aligns the rotor away from the wind within a second range relative to a reciprocal heading of the wind direction, the second range defining a reverse zone of reduced or no vibrations caused by the incoming wind.

A system and method reduce vibrations in a blade mounted on a hub of a wind turbine rotor when the rotor is in a limited yaw capacity state with a defined allowable yaw sweep. Vibration risk zones are defined based on wind direction and actual wind parameters acting on the blade are determined with a sensor. With a controller and based on the actual wind parameters, the following conditions are determined: (a) if a present yaw position of the rotor is in one of the vibration risk zones; and (b) if one or more of the wind parameters is at a risk threshold associated with the vibration risk zone. When conditions (a) and (b) are met, a yaw command is issued to yaw the rotor to a new yaw position within the allowable yaw sweep where the rotor is not in one of the vibration risk zones or is in a different vibration risk zone where the one or more wind parameters are not at the risk threshold associated with the different vibration risk zone
