ABSTRACT:
A gas turbine generator includes a first gas turbine 20 having an air compressor 21, first turbine 24a and a first combustor 25a; a second gas turbine 22 having a second turbine 24b and a second combustor 25b; a generator 27 driven by the first gas turbine and the second gas turbine; and a coupling 23 arranged between the generator and the second gas turbine for connection and disconnection. When residual steam is sufficiently supplied, the residual steam is fed to the first combustor and the second combustor while connecting the coupling, and when the residual steam is not sufficiently supplied, the residual steam is fed to only the first combustor while disconnecting the coupling.
