Resumen de: WO2026043490A1

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.
