The torsional vibration of turbine-generator shafts can be excited by the disturbance of electric power system. The coupling interaction between the system disturbance and the torsional vibration makes turbine-generator oscillate. Alternate torsional stress due to large torsional vibration shortens the life of shafts, even makes shafts break. The natural characteristics and responses of torsional vibration of shafts of 200MW turbine-generator are simulated and analyzed under the catastrophic accidental condition. The causes for the breaking of bolts between the coupling of intermediate-pressure and low-pressure rotor and the coupling of generator and exciter rotor are discussed. The results are identical with the data recorded in the field.
