DIAGNOSIS AND CURE OF VIBRATION FAULT ON GENERATOR NO1 AT TIELING POWER PLANT[J]. Thermal power generation, 2001, (5): 53-57. DOI: 10.19666/j.rlfd.2001.05.018.
Generator No1 at Tieling Power Plant had a problem of suddenly occurred vibration under high-load condition. It was found that the cause of vibration was due to rotor’s thermal unbalance resulting from the unsymmetrical axial force produced by obstructed hot expansion of the rotor winding. Draw-out and inspection of rotor on the field have proven the result of analysis
and the vibration fault of generator was successfully eliminated after cure.
