Self excited torsional vibration in single shaft combined cycle turbine-generator train
Abstract
This case history describes the investigation of the source of unstable behavior of a newly commissioned single-shaft, combined cycle, power generator unit. The source was found to be nonlinear operation of the flexible coupling between the generator and steam turbine, causing self-excited parametric torsional oscillations, transferred into radial vibration, detectable in monitoring system.
