It is important to reduce the change of the output of wind turbine to spread wind power generation more. Then, we aimed to look for the method of a better control of wind turbine to reduce the change of the output. Concretely, we examined the change in the aerodynamic characteristic of the wind turbine when the pitch angle and the rotational speed were changed by the numerical analysis. The acceleration potential method was used for the numerical analysis. As a result, when the pitch angle or rotational speed is changed linearly, it has been understood that the torque decreases greatly at once afterwards and then gradually approaches a regular value. In addition, damping time and the magnitude of the overshoot at that time is large like time when the velocity of the wind is low.
