ABSTRACT:
In a method for operating a gas turbine centre in the vicinity of the group nominal full-load conditions, the cooling of the working fluid before and/or during the compression is set in such a way that the respectively attainable full-load power is above the current power. Rapid power demands can therefore be rapidly satisfied by an increase in the turbine inlet temperature or by opening an adjustable inlet guide vane row, whereas the control of the cooling effect, which has a tendency to be more sluggish, is employed to adjust the full-load operating point.
