Patent ID: 7104071

Claim:
A method for operating a gas turbine group, the method comprising: compressing a working fluid in at least one compressor; supplying a heat flux to the compressed working fluid in a heat supply component thus heating the compressed working fluid; passing the heated working fluid from the heat supply component into at least one turbine; expanding the working fluid in said turbine; generating shaft power while expanding the working fluid in the turbine; driving the compressor with a first fraction of the shaft power; driving a power consumer with remaining useful shaft power; cooling the working fluid by applying a cooling power at a position selected from the group consisting of before the compression, during the compression, and both before and during the compression; regulating the cooling power dependent on a control deviation of the useful shaft power; evening out the control deviation in regulating the cooling power; in parallel with regulating the cooling power regulating the heat flux supplied to the compressed working fluid for continuously maintaining at least a turbine inlet temperature of the working fluid substantially constant.
