| Abstract: | Steam turbine generator rotor vibration characteristics and electromagnetism characteristics were analyzed, when steam turbine generator occurred the fault of eccentricity between stator and rotor, inter-turn short circuit in rotor coil, partial jam in hydrogen cooled rotor, interior friction between exciting coil circuit and rotor or shroud ring, friction between stator and rotor, linkup-looseness in rotor pedestal system, machinery imbalance. It can provide the analysis method for vibration fault diagnosis of steam turbine generator. |
