A 12MW steam turbine generator unit has the problem of over-vibration after major overhaul and requires emergency shutdown for handling. Through the field test analysis on vibration ,the main fault causes are lack of foundation stiffness and dynamic unbalance of generator rotor. After handling the fault in according with the handling plan,the vibration fault is eliminated and the long-periodic safe and stable operation of the unit is guaranteed.
