FIELD: turbines or turbomachines.
SUBSTANCE: control method of asynchronous torsional oscillations of shaft turbine pipeline contains the following stages: measuring (112) the rotation speed of said shafting line for a period of time and generating a signal indicating said rotation speed during said period of time, based on the measured rotation speed; performing (122) analysing spectrum of said signal, to determine, for at least one given frequency, the amplitude of variation of said rotation speed on said given frequency; comparing (124) said amplitude with at least one predetermined amplitude threshold value for said frequency; generating (126) an alarm signal if said amplitude exceeds at least one predetermined amplitude threshold value.
EFFECT: disclosed is a method of controlling asynchronous torsional oscillations of shaft turbine pipeline.
