Abstract
A method and system for reducing a torsional movement and/or a torsional loading of a tower of a wind turbine is disclosed includes generating a tower torsion signal with a detection system and providing the signal to an asymmetric load control assembly. The tower torsion signal may correspond to an actual torsional movement of the tower or a torsional loading of the tower. The asymmetric load control assembly is configured to mitigate an asymmetric load acting on the wind turbine using the tower torsion signal.
