Abstract
A power generating apparatus has a power generatorfor generating AC power, a gas turbine enginefor driving the power generator, and an inverter devicefor converting the AC power into commercial AC power. The power generating apparatus includes an interconnection switch Sfor connecting an output of the inverter devicewith a commercial AC power supply system, a first voltage detectorfor detecting a DC power supply voltage Vdc-in of the inverter device, and a second voltage detectorfor detecting a full-wave rectification voltage of the commercial AC power supply system. The power generating apparatus also includes an interconnection control partfor closing the interconnection switch Swhen the DC power supply voltage of the inverter deviceexceeds the full-wave rectification voltage of the commercial AC power supply system.
