<p>An object of the invention is to enable a control on active power according to a request of a utility grid. In a case where a request for changing a maximum value of active power and a newly defined maximum value of active power are received from the utility grid side, a maximum value of an active power demand value set to a rated value is changed to the newly defined maximum value of active power at a predetermined change rate or less. There are provided a detecting unit (rotor speed detecting unit) 50 for detecting a parameter related to an operation state, and an demand value obtaining unit 51 for obtaining an active power demand value corresponding to the operation state parameter detected by the detecting unit 50 based on first information in which a parameter related to an operation state and an active power demand value are associated with each other. In a case where a request for changing a maximum value of active power and a newly defined maximum value of active power are received from the utility grid side, the maximum value of the active power demand value in the first information, which is set to the rated value, is changed to the newly defined maximum value of active power at the predetermined change rate or less.</p> |
