A novel three-phase transformer hysteresis model in MATLAB^{TM} Simulink

摘要

This paper presents a new transformer model displayinghysteresis using the MATLAB{exttrademark} Simulink environment. Theproposed model displays a complete scheme for the simulation of3-phase transformers. The new model is mainly based on thetransmission line model and the Jiles-Atherton model of a power systemusing lumped parameters. Jiles-Atherton model parameters weredetermined by curve fitting and numerical optimization iteration. Thedeveloped model is particularly suitable for fault analysis andprotective relaying studies under harmonic conditions where thetransformer is driven into the nonlinear regime. The performance ofthe method was evaluated by both theorical and experimental data.
