Analysis and Modelling of High Frequency Effects on Synchronous Generator’s Armature Conductors

Abstract

This paper investigates the accuracy of the subdomain modelling technique for high frequency copper loss calculation in stator windings of synchronous generators. The methodology's accuracy is studied at a slot level up to 10 kHz against FE model with realistic conductor dimensions. The analysis demonstrates that improper conductor area representation and eddy current reaction negligence causes increasing error with increasing frequencies. A modified subdomain model is then proposed to address these challenges which has proven to show a good match with a corresponding FE model.
