Abstract
This paper analyzes the vibration problem of No.2 135 MW turbogenerator unit in a power plant
and find that the vibration is mainly due to the first-order unbalance and thermal deformation of the rotor.After dynamic balance of the rotor
the vibration fault of the generating unit is eliminated with a better vibration grade to achieve safe operation of the generating unit.
