Modeling of hysteresis dependent magnetization inductance for a brushless exciter model

In this paper, a model is developed to incorporate the magnetic hysteresis effects into a brushless exciter dq-axes model. The developed model reconstructs the magnetization flux linkage-current loops using few measured parameters. The model can also achieve computationally efficient simulation by utilizing the Energetic model for the steel hysteresis loop modeling. The developed model is then applied to reconstruct the measured flux linkage-current loops in an Epstein frame test fixture with an air gap. The simulation results agree well with the measured loops, confirming the validity of the proposed model.
