A method for detecting malfunctions in a combustion chamber of a gas turbine plant includes providing dynamic pressure signals (P1I, P2,...., PN), each indicative of a dynamic pressure at the outlet of a respective burner of a combustion chamber of the plant. Frequency spectra (S1(f), S2(f),..., SN(f), S1*(f), S2* (f),..., SN *(f)) of the dynamic pressure signals (P1, P2,..., PN) are calculated, the malfunctions of the burners are recognized according to these spectra. Each burner subject to malfunctioning is identified according to a bijective correlation between the burners and the respective dynamic pressure signals (P1, P2,..., PN). |
