In a power generation system, exhausted fuel gas exhausted from a solid oxide fuel cell (SOFC) is used as a fuel of a first combustor or a second combustor of a gas turbine, and at the same time, a part of compressed air compressed by a compressor of the gas turbine is used to drive the SOFC. The gas turbine includes the first combustor for burning fuel gas which is different from the exhausted fuel gas, a first turbine configured to be driven by combustion gas supplied from the first combustor, the second combustor for burning at least a part of the exhausted fuel gas, and a second turbine coupled with the first turbine and configured to be driven by combustion gas supplied from the second combustor.

Combined power generation system comprising a fuel cell and a gas turbine engine

A power generation system includes a gas turbine having a compressor, a combustor, and a turbine, an inlet guide vane in an air intake port in the compressor, a first compressed air supply line for supplying compressed air compressed by the compressor to the combustor, a solid oxide fuel cell (SOFC) having an air electrode and a fuel electrode, a second compressed air supply line for supplying at least part of the compressed air compressed by the compressor to the air electrode, a control valve in the second compressed air supply line, and a control device for opening the control valve when the SOFC is activated and changing a degree of opening of the inlet guide vane from a preset reference degree of opening.
