Hysteretic iron-core modelling for inrush current transients using Jiles-Atherton model (original) (raw)

2016 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2016

Abstract

This paper presents an improved transformer core modelling for slow-front transients caused by 50 Hz line energization. Two single-phase 16 kVA, 11 kV/ 250 V oil-immersed distribution transformers with only basic nameplate data available are used for the study of magnetising and sympathetic inrush transients. Instead of using the classic Steinmetz Saturation Transformer Model as in previous study, the Jiles-Atherton model is applied which has the capability of representing minor loop operations and de-energization. Its parameters are evaluated by a series of differential evaluation algorithm with a few reasonable assumptions. Simulations of inrush current are carried out and the results compared with the experimental measurements. It is shown that improvement in accuracy is achieved with the use of the Jiles-Atherton model.
