摘要：

In the proposed paper, the characteristic of unbalance magnetic pull (UMP) produced by turbine generator field winding serious inter-turn short circuit (FWSISC) is analyzed, then rotor vibration feature on the condition of FWSISC is studied, and the difference of rotor vibration feature caused by FWSISC and other reasons is also analyzed, A detection method of FWSISC based on the rotor vibration characteristic is proposed. Whether FWSISC occurs can be detected by analyzing rotor vibration amplitude change feature, spectrum feature, the relationship between rotor vibration and field winding current. Finally, the validity of detection method is verified by a 300MW turbine generator FWSISC example.
