Abstract

See full text

An apparatus for monitoring torsional vibrations of a rotating shaft system such as for a turbine generator in which torsional vibrations at certain positions of the rotating shaft system are detected by detectors and the detected vibrations are converted into torsional vibration at an arbitrary position of the rotating shaft system by using an operation device having desired transfer characteristics, said arbitrary position is monitored on torsional vibration on the basis of the converted torsional vibration.
