Abstract

There is provided a wind power generating system including: a rotor that is provided with a blade of which a pitch angle is changeable and that rotates by receiving the wind; a generator that generates power by using rotation energy of the rotor; and a control device that controls a device that is included in the wind power generating system. In a case where a speed is equal to or higher than a wind speed at which a rotation speed of the generator reaches a rated speed and a speed is equal to or lower than a wind speed to reach rated generation power, the control device performs feedforward control of generator torque that is transmitted as a command to the generator and adjusts a change in input energy, based on a wind speed applied to the wind power generating system.
