The research of aircraft generator stator winding faults has great significance to the generator protection design, and the conclusion of the research can be further used to provide a reference for aircraft maintenance decision. In this paper, the inductance parameters of the aircraft generator were calculated at the beginning based on the air-gap permeance method. Then the aircraft generator model with and without stator winding internal fault were built according to the multi-loop method. As two typical fault scenarios of the aircraft generator, inter-turn short circuit and inter-phase short circuit were introduced into the simulation model. And the simulation results show that the excessive short line current has a significant impact on the performance of the motor, which proves that the protection device is necessary for the generator. In addition, the harmonic distribution of the fault current was compared with the case without fault injected, which leads to the observation that the stator current contained more odd harmonics, and the excitation current contained more even harmonics. What's more, such harmonic analysis can provide a theoretical basis for fault diagnosis research. |
