The invention relates to the vibration damper systems (here, method and
apparatus) for active removal of beyond-normal internal vibrations from
turbine-generator-sets [T-G-Ss]. The invention relies on dynamic forces
generated by at least a pair (when symmetrically placed) of "wings" or by
at least one "wing" (when centrally placed), or combination of that, and
associated hardware mounted on the bearing housing, which operate to
offset internally produced vibrations in an active or "real time"
fashion. This is in contrast to the typical method of taking the
turbine-generator off-line, shutting it down and then eliminating the
source of vibration. The invention allows the generator to remain
operational during adjustments. Thus, it remains on-line producing
electricity and associated revenue. The system may be installed at
presently operating T-G-Ss. It also foresees the simple developments to
be done in future designed T-G-Ss for use of this method. The use of
invention provides a real solution to internal vibrations that develop in
turbine-generator-sets throughout their lifetime. This method can also be
utilized by other or materially different processes in all kind of
machinery, apparatuses and technologies for as long it successfully damps
vibrations.
