A method for running up a gas turbine plant (1) is disclosed. In the method, a fuel (6) is injected into the combustion chamber (5) via a plurality of pilot burners (10) and premix burners (11). During the start-up and in a lower load range, the combustion chamber (5) is operated in the pilot mode,

A method for running up a gas turbine plant (1) is disclosed. In the method, a fuel (6) is injected into the combustion chamber (5) via a plurality of pilot burners (10) and premix burners (11). During the start-up and in a lower load range, the combustion chamber (5) is operated in the pilot mode, and, at a specific time point, the combustion chamber (5) is changed over from the pilot mode to the premix mode. The changeover time point from the pilot mode to the premix mode depends on a variable changeover temperature (TSWO), and this changeover temperature (TSWO) is determined from pulsations occurring in the flame of the combustion chamber (5).
