Abstract：As wind turbines become larger and lighter, they are experiencing more severe shaft torsional vibrations. Therefore, the suppression of turbine shaft torsional vibrations is becoming more important. This paper compares three common maximum power point tracking(MPPT) control algorithms. All three methods use generator speed feedback to enhance the drive shaft damping. An advanced conventional MPPT control method was then developed with an extra order added to the MPPT command to suppress shaft torsional vibrations. The result suppresses the torsion vibrations of the drive shaft, while ensuring that the wind turbines work at the maximum power point. Simulations verify the effectiveness of the theoretical analyses and this method.
