PROBLEM TO BE SOLVED: To shorten time up to self-sustaining of a system and to miniaturize a starting motor by providing a passage communicating from an air reserving tank of operating gas made into high pressure to a gas turbine entrance and a passage communicating with a heater entrance and disposing a device for controlling supply of operating gas on each passage. SOLUTION: Entrance gas supply lines 5, 4 for supplying operating gas 15 from an air reserving tank 11 to a gas turbine 6 and a heater 8, respectively, are provided between the air reserving tank 11 and an entrance of the gas turbine 6 and between the air reserving tank 11 and an entrance of the heater 8, respectively. In each line 5, 4, entrance opening and closing valves 14, 13 are interposed. When a system is started, a gas compressor 7 is driven by a starting motor 12, operating gas 15a is compressed, and an output is generated in also the gas turbine 6 by supplying high pressure operating gas from the air reserving tank 11 to the gas turbine 6 via the gas supply line 5 at almost the same time as this compression. At the same time, the heater 8 is operated and operating gas 15b of high pressure can be early supplied to the gas turbine 6.
