Identification of Transformer Core Hysteresis Loop Model Parameters

By means of the MATLAB genetic algorithm toolbox,model parameters are divided into two groups by the hysteresis loop measured by experiment.Then the 5 parameters in the Jiles-Atherton model are identified by hysteresis loop saturation and loss characteristics.The effectiveness of the method proposed in this paper is verified through a concrete example.The simulation results show that the method fits the hysteresis loop well.
