Notes on parameter estimation for single-phase transformer

IEEE Transactions on Industry Applications, 2020
This article investigates the inaccuracies of identifying parameters for a single-phase transformer. In addition, in this article, two new transformer parameter estimation algorithms based on recently developed optimization techniques, as well as an objective function, are proposed for the transformer parameter estimation to improve the estimation ...

Idling Mode Simulation of Single-Phase Transformer

2019 IEEE International Conference on Modern Electrical and Energy Systems (MEES), 2019
A unifying mathematical model of the single-phase transformer is developed. This model superposes the external electrical circuit and an electromagnetic fields model, which describing the processes of electromagnetic energy conversion in a transformer.

Electromagnetic and thermal behavior of a single-phase transformer during Ferroresonance considering hysteresis model of core

International Journal of Electrical Power and Energy Systems, 2020
Ferroresonance leads to a high saturation of the transformer core. This causes severe rise of the amplitude of current and voltage of the transformer and leads to current and voltage non-sinusoidal waveforms.
