To investigate the structural dynamics of a permanent magnet synchronous generator (PMSG) based on a direct drive (DD) wind turbine concept, a multi-body simulation (MBS) model is developed. Furthermore, a co-simulation can be carried out with other software to research the behavior of the turbine in all kinds of load cases. Simulation results show that the flexible rotor induces vibrations in the drive train and changes the frequencies of vibrations significantly. A modelbased generator control is designed to actively reduce the mechanical stress in the drive train. Compared with the standard generator torque control the new controller brings more damping in the drive train without energy loss. This controller can be further improved with a more detailed equivalent model.
