PROBLEM TO BE SOLVED: To provide a power generation system to increase a turbine exhaust gas mass flow.SOLUTION: A first integral compressor 106 of a first turbine component 104 has a flow capacity greater than an intake capacity of a first combustor 108 and/or the first turbine component 104, creating an excess air flow 200. A second gas turbine system 140 includes similar components to the first gas turbine system except not having excess capacity in its compressor. A turbo-expander 252 is operatively coupled to the second gas turbine system. Control valves 256, 266 control a flow of the excess air flow from the first gas turbine system 102 to the second gas turbine system and/or the turbo-expander 252, and a flow of a discharge 272 of the turbo-expander 252 to an exhaust 172, 174 of at least one of the first turbine component and the second turbine component.SELECTED DRAWING: Figure 1 |
