英文摘要：
Aiming at the complex force environment for turbine generator rotor and the chmlging rotor vibration state, two typical rotor fundamental frequency vibration sources were selected as study objects, namely, rotor winding inter-turn short-circuit and static eccentricity faults. With the help of finite element simulation tool＇ powerful computing capabilities, the unbalanced magnetic pull by dynamic eccentricity and field windings inter-turn short circuit were studied, the impacts of different fault variables on the unbalanced magnetic pull size and direction were analyzed, which lays the foundation for a comprehensive study of all generator rotor forces and the diagnosis of field winding inter-turn short-circuit fault based on rotor vibrations.
