Damping Control Study of the Drive Train of DFIG Wind Turbine

Abstract

In this paper, damping controller for dynamic and transient control of a variable speed wind turbine is presented. The phenomenon of drive train oscillations in wind turbines is discussed. It is illustrated how the damping controller is able to reduce the oscillations of the drive train significantly and mitigate fatigue damage due to drive train oscillations we studied the effect of damping controller on the natural frequency associated with drive train torsional oscillations and its impact on drive train damper design.
