Abstract

Modelica models for transient simulation of magnetic hysteresis are currently being developed at Technische Universität Dresden. This paper gives an overview about the present state of the work. Two hysteresis models have been implemented so far in Modelica and are currently optimised and tested: the rather simple but efficient Tellinen model and the more complex and accurate Preisach model. Utilisation of the Tellinen model together with components of the Modelica.Magnetic.FluxTubes library is exemplarily shown with transient simulation of a three-phase autotransformer. Additionally; an efficient implementation of the Preisach model is described and a first comparison between the Tellinen and the classical Preisach hystesis model is presented. It is planned to include the developed hysteresis models into the above-mentioned FluxTubes library after their further optimisation and validation with own measurements. These models will especially allow for the estimation of iron losses and for accurate computation of saturation behaviour during Modelica-based design of electromagnetic components and systems. This becomes increasingly important with the growing requirements regarding energy efficiency and mass power densities of such systems.
