Abstract

Fremgangsmåte og anordning for å kunne bestemme når det forekommer roterende stall i en kompressors (1) turbinblad (3) hvor i det minste ett kompressortrinns (2) bladpasseringsfrekvens samt den tilhørende vibrasjonsenergi overvåkes, idet normal bladpasseringsfrekvens utgjøres av kompressorens (1) arbeidsomdreiningshastighet multiplisert med antall turbinblad (3) i trinnet (2), og hvor begynnende roterende stall i et kompressortrinn (2) indikeres når vibrasjonsenergien (28) ved den normale bladpasseringsfrekvens (34) i kompressortrinnet (2) faller til under en forutbestemt første verdi (40) samtidig som vibrasjonsenergien (30) ved en bladpasseringsfrekvens (42) over den normale bladpasseringsfrekvensen (34) stiger til over en forutbestemt andre verdi (44).
