Modeling of five-phase dual stator-winding induction generator with third harmonic injection

In this paper, the model of the third-harmonic-injected five-phase dual stator-winding induction generator (FPDWIG) is presented. There are two sets of five-phase concentrated stator windings in this generator. One is called as the control winding, the other is termed as the power winding. For improving the power density, the third harmonics are injected in this generator. With the consideration of the differences of the fundamental and third harmonic spaces, the model of the third-harmonic-injected FPDWIG is built in the rotating d₁-q₁-d₃-q₃ arbitrary reference frame. The dynamic equivalent circuits of FPDWIG in the rotating d₁-q₁-d₃-q₃ arbitrary reference frame are given. Based on this method, FPDWIG simulating model is built in the MATLAB/SIMULINK and the simulation results is given for verification.
