Abstract
In a method for regulating a gas-turbine assembly, essentially consisting of a compressor unit (1), of an HP-combustion chamber (4), of an HP-turbine (6), of an LP-combustion chamber (9), of an LP-turbine (12) and of a generator (14), the rating of the fuel quantity (FH) for the HP-combustion chamber (4) is carried out responsive to a corrected temperature signal which is formed by the value of the temperature (T13) at the outlet of the LP-turbine (12), reduced by the particular temperature rise (.DELTA.T) detectable there. This temperature signal (T13-.DELTA.T) is recorded in that the temperature rise (.DELTA.T) generated by the fuel quantity (FL) introduced into the LP-combustion chamber (9) is subtracted from the measured temperature at the outlet of the LP-turbine (12). The uncorrected temperature signal at the outlet of the LP-turbine (12) is used for rating the fuel quantity (FL) for the LP-combustion chamber (9).
