Abstract

Modelling transformers and the power grid interaction is crucial to maintain a reliable and safe power grid. However, often the available transformer data is incomplete, missing or not accessible. Different approaches have been published for modelling transformers with different amount of data and degree of detail. The aim of this approach is, to easily setup a fast transformer model to study the transformer behaviour and grid interaction. The required measurements can be done easily in the field or substation. The measurements are used to setup the Jiles-Atherton hysteretic model. The model approach is based on the duality principle, transforming the magnetic circuit into its electric equivalent. In this work we demonstrate this approach on a 3-phase 3-limb 2-winding 50 kVA power transformer. The correlation between simulation and measurement are at least 97 %. Therefore, this approach can be used in industry and research to model transformers and study their behaviour and grid interaction.
