<P>PROBLEM TO BE SOLVED: To more stabilize unstable output of power generation in wind turbine generation. <P>SOLUTION: A wind turbine generator includes: a first generator 5 having a rotor rotating together and coaxially with a rotating shaft 2 which receives wind force and rotates; a flywheel 7 coaxial with the rotating shaft 2 and arranged through a one-way clutch so as to be in a state rotating together with the rotating shaft 2 in a given rotation direction of the rotating shaft 2 when the rotating shaft 2 is accelerated and to be disconnected from the rotating shaft 2 and rotate under inertia when the rotating shaft 2 is decelerated; a second generator 9 having a rotor rotating together and coaxially with the flywheel 7; an electric motor 70 rotatively driving the flywheel in the given rotation direction; a drive electric power supply section supplying drive electric power to the electric motor 70; a control section performing the drive electric power supply to the electric motor 70 when the rotation speed of the flywheel 7 detected at a rotation speed level detection section is below a predetermined level; and an output section outputting the generated electric power of the generators 5, 9 to the outside. <P>COPYRIGHT: (C)2012,JPO&INPIT |
