摘要
It is an object to stabilize utility grid even when an unexpected fluctuation in the frequency of the utility grid occurs. A wind turbine generator (1) includes a rotor (7) that rotates by wind power, a generator (5) that is driven by rotation of the rotor (7), and a control device (20) that controls a power output of the generator (5) to increase while a rotational speed of the generator (5) decreases when a frequency of a utility grid (13) becomes smaller than or equal to a predetermined rated frequency and when the rotational speed of the generator (5) is greater than or equal to a first predetermined value. In this way, even when the frequency of the utility grid (13) fluctuates, the frequency fluctuation can be suppressed, and the utility grid (13) can be stabilized.
