Abstract:
A gas turbine generator comprising:a generator;a first gas turbine assembly operatively connected to drive the generator, and including a first turbine having an intake and an exhaust, a first combustor having an intake and an exhaust operatively connected to output exhaust gas to the intake of the first turbine;a second gas turbine assembly operatively connected to drive the generator, including a second turbine having an intake and an exhaust, a second combustor having an intake and an exhaust operatively connected to output exhaust gas to the intake of the second turbine;an air compressor having an intake and an exhaust operatively connected to output compressed air to the intakes of the first and second combustors;a coupling arranged between the generator and the second gas turbine having a first configuration coupling the second gas turbine to the generator, and a second configuration decoupling the second gas turbine from the generator; anda mixed gas line connected to the inputs of the first and second combustors; anda controller, operatively connected to said coupling and programmed to couple and decouple said coupling, and connect and disconnect said mixed gas line from the second combustor, responsive to a flow rate of steam in said mixed gas line.
