Using the drive train for active damping of oscillations in rotor blades in gearless wind-energy-converters with PMSM

With the increasing nominal power of wind energy converters, an optimized management, a higher level of efficiency and reduced costs are needed. In search of suitable generator systems for wind turbines in the MW class, the permanent-magnet synchronous machine as a generator moves to the focus of current discussions. The Rotor and its blades are able to oscillate due to various dynamic loads a wind energy converter is exposed.
