Claim:
1. A power generation apparatus comprising: 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; an expander that rotationally drives the induction generator by a working medium supplied thereto; a pump provided to supply a controlled amount of the working medium to the expander; and wherein the control unit comprises means for closing the switch upon a lapse of a predetermined amount of time after the expander starts to rotationally drive the induction generator by the working medium supplied thereto, to start up the power generation apparatus, the predetermined amount of time being predetermined as an amount of time elapsed from the start-up of the power generation apparatus that is required for a difference between a rotation frequency of the induction generator and the predetermined frequency of the alternating current flowing from the electrical path into the induction generator to reach a predetermined range.
