Abstract
A power generation apparatus according to the present invention includes: an induction generator; a switch that opens or closes an electrical connection path connecting the induction generator to an electrical path in which an alternating current of a predetermined frequency flows; a control unit that controls the opening and closing state of the switch; and an expander that rotationally drives the induction generator by a working medium supplied thereto. In order to suppress a starting current generated when starting the induction generator while suppressing an increase in cost, the control unit closes the switch after the working medium is supplied to the expander so that the expander starts to rotationally drive the induction generator.
