The instantaneous wind velocity time-history under the storm conditions was simulated by the linear filtering method. The simulated instantaneous wind speed was used to analyze the wind-induced response of wind machine tower drum. The turbine tower drum’s wind vibration control which uses the tuned mass damper damping technology (TMD) in the storm was studied. The results show that the dynamic response at top of the tower drum exhibits strong randomness and volatility under the storm wind. TMD has a good effect on the wind vibration control of the wind turbine tower drum. The wind vibration control effect of TMD to wind turbine tower drum increases with the increase of mass ratio and damping ratio, and tends to become stable. The
