Abstract (en)
[origin: EP2239505A1] The method involves identifying resonances of a characteristic variable by a spectrum, and determining amplitude values of the resonances. A stability parameter (9) is calculated as a function of the values. A lower distance value and/or upper distance value, on which the stability parameter lies above a lower threshold value and/or below an upper threshold value, are determined. The threshold values are selected such that the parameter lies on one of the threshold values if a combustion chamber is operated in an operating state with a humming tendency higher than a permissible value. Independent claims are also included for the following: (1) a method for operating a gas turbine (2) a control device for controlling operation of a gas turbine.
