A large capacity turbine generator has tertiary mode of rotor vibration. Then the thermal unbalance of rotor has a large effect on increasing its vibration. This study presents a method for prediction and diagnosis in order to distinguish the thermal unbalance causes by using rotor condition supervision equipment and rotor thermal vibration measuring equipment. Furthermore this paper deals a method for actual adjustment in order to decrease the thermal vibration stroke by using thermal vibration operator. By this method, a satisfactory vibration was achieved for a large capacity turbine generator.
