PURPOSE: To safely perform the start control at a high wind velocity and positively improve the startability at a low wind velocity by changing a blade setting angle in steps to the blade setting angle during the normal rotation when starting blades in a stop condition.
CONSTITUTION: The blade angle of a wind prime mover with a predetermined value of a blade setting angle in a stop condition is changed in steps to the condition of the blade fitting angle β2 during the normal rotation. By monitoring the operational condition of the wind prime mover at each step, the wind prime mover can be safely started even at a high wind velocity, and also a normal operational condition can be effectively attained. In case the rotation is stopped in a condition of the blade fitting angle β2 of the normal operational condition at a low wind velocity, the wind prime mover can be positively started at a lower wind velocity by changing the blade fitting angle to a condition where the maximum rotating torque can be obtained.
