Patent ID: 11542874

Abstract:
There are provided a gas turbine system and a gas turbine power generator that can achieve an increase in output power and a decrease in fuel efficiency together and curb an increase in cost and weight. There is also provided a gas turbine system that can stably supply a necessary amount of air to a combustor even when a compressor and a turbine on one side are stopped. The gas turbine system 1 includes a plurality of gas turbine units 2 and 3, a single combustor 4, a plurality of pipes 5, a plurality of on-off valves 6, and a control unit 7. In a first operation mode, the control unit 7 controls switching-on/off of the on-off valves 6 such that air is supplied to the combustor 4 from a first compressor 21 and a second compressor 31. In a second operation mode, the control unit 7 controls switching-on/off of the on-off valves 6 such that air compressed in stages while sequentially passing through the first compressor 21 and the second compressor 31 is supplied to the combustor 4, and supplies air to turbines such that they can be expanded in stages.
