Abstract (en)
[origin: EP1688671A1] Pressure pulsation (P) occurring during a gas turbine's (1) operation is measured. Generated from measured pressure pulsation, a pulsation time signal (PZS) is transformed into a pulsation frequency signal (PFS) used to determine a pulsation level (PL) for a predefined monitoring frequency band (12). An independent claim is also included for a control system for a gas turbine.
