Improved Dynamic E&S Vector Hysteresis Model for Non-Elliptic Magnetic Flux Density Condition and its Implementation to Finite Element Method for Iron Loss Analysis of a Three-Phase Transformer

Abstract:

This paper proposes an improved dynamic E&S vector hysteresis model to increase modeling accuracy especially for non-elliptic B-waveforms, and its implementation to finite element method. The major improvements of the suggested model are on the determination of the geometric parameters of a non-elliptic B-waveform, and the calculation of the magnetic reluctivity and hysteresis coefficients. The proposed model is combined with FEM and applied to the iron loss analysis of a three-phase transformer.
