A wind-driven electricity generation device (1) is provided with a wind wheel (3) which is subjected to wind power and rotates in a specific rotational direction about a predetermined rotating shaft (2). The wind-driven electricity generation device (1) is also provided with: a first electricity generator (5) which has a rotor (4) disposed so as to rotate together and coaxially with the rotating shaft (2) and which generates electric power by the rotation of the rotor (4) caused by the rotation of the rotating shaft (2); a flywheel (7) which is coaxial with the rotating shaft (2) and which is disposed through a one-way clutch (6) so that, when the rotating shaft (2) is increased in speed, the flywheel (7) rotates together with the rotating shaft (2) at an increased speed in the specific rotational direction of the rotating shaft (2), and so that, when the rotating shaft (2) is reduced in speed, the flywheel (7) is disconnected from the rotating shaft (2) and rotates under inertia in the specific rotational direction; a second electricity generator (9) which is different from the first electricity generator (5), the second electricity generator (9) having a rotor (8) which is disposed so as to rotate together and coaxially with the flywheel (7) and generating electric power by the rotation of the rotor (8) caused by the rotation of the flywheel (7); and an output section (output means) (10) which outputs either the electric power generated by the electricity generator (5) or the electric power generated by the electricity generator (9). The configuration can stabilize the unstable output of electric power generated by wind-driven electricity generation. |
