Abstract：The wind turbine dynamic torque control technology based on wind speed model is studied. Firstly, the wind speed estimation model is built based on the extended Kalman filter, and the dynamic equation is established and linearized by using the air and structural dynamic characteristics of the wind turbine. When using the extended Kalman filter to design the state observer, the continuous discrete hybrid type iterative way is used to construct the wind speed estimation model. Then the aerodynamic torque of the wind turbine is estimated by the wind speed model, and the dynamic torque feed forward control algorithm of the wind turbine is established by the estimated aerodynamic torque. The stable controller design method is given. Finally, taking the 2MW wind turbine as an example, the wind speed estimation feed forward control algorithm is simulated and field tested. The results show that the estimated wind speed model is in good agreement with the field measured data, the wind speed correlation is 98.4%. Based on the wind speed model, the dynamic torque control method of wind turbine can effectively reduce the ultimate load of wind turbine.
