Abstract In order to study the operation of 12-phase rectifier generator system when the stator winding is short circuited, a system model based on finite element field-circuit coupling simulation is established. The model takes into account the effects of cogging effect, harmonics and so on, has high degree of accuracy, which is suitable for fault diagnosis of generator and rectifier part. According to the established model, stator winding inter-turn short circuit faults of 12-phase rectifier generator system were analyzed. The waveforms of the system load voltage, phase voltage, phase current and short circuit current were obtained, and the effect on stator winding inter-turn short circuit faults of the system was indicated after analyzing waveforms. Through comparative analyses, the simulation results coincide well with experimental results, which verify the rationality and accuracy of the model and analysis.

Key words： 12-phase rectifier generator stator winding inter-turn short circuit finite element field-circuit coupling simulation
