摘要：It is an object to reliably and swiftly restore voltage of a utility grid, whichdecreased due to a utility grid failure or the like, to reference voltage. A generatingapparatus includes: a generator connected to a utility grid; a voltage detecting sectionfor detecting voltage of a utility grid 2; and a control section 21 for determining reactivecurrent corresponding to the voltage obtained from the voltage detecting section 27based on voltage current correlation information in which the voltage of the utility grid 2and the reactive current to be supplied to the utility grid 2 are correlated with each otherand controlling the electric power converting section 27 to regulate the reactive currentto be supplied to or absorbed from the utility grid 2. The apparatus further includes aninformation changing section 22 for changing the voltage current correlation informationto increase an amount of the reactive current with respect to a variation in the voltage inthe voltage current correlation information, in the case where the voltage of the utilitygrid is not in a predetermined range set in advance after a predetermined time periodhas passed since the voltage of the utility grid varied by a predetermined amount ormore.
