From the point of view of practical problem in operation of large wind turbine, due to weak damping of drive chain, according to drive chain resonance problem caused by torque change in the vicinity of the rated torque, a dynamic torque damping controller for large wind turbine, which is based on fast Fourier transform and digital iflter technology with dynamic phase compensation has been designed. The dynamic torque damping controller can successfully restrain the resonance of drive-chain and keep the wind turbine operate stably.
