Mathematical model and simulation of stator winding inter-turn short circuit fault of PMSG

  • Received Date: 2018-01-19
  • Aiming at the problem of stator winding inter-turn short circuit fault of permanent magnet synchronous generator(PMSG), the fault factor of inter-turn short circuit was introduced based on the analysis of PMSG general mathematical model, and the mathematical model of stator winding inter-turn short circuit fault in three-phase stationary coordinates was derived. In addition, the simulation model based on Matlab/Simulink was established, and the operating conditions of PMSG normal and stator A phase winding inter-turn short circuit under different severity were studied using time-domain simulation and FFT analysis. Simulation results showed that the stator current would increase with the severity of the stator winding inter-turn short circuit fault of PMSG, and when the stator winding short circuit turned to reach a certain number, corresponding stator current amplitude changes would be more obvious.
