Turbo Generator Concept Without Winding Overhang Using a Multiphase Transformer

Abstract

This paper is about an innovative multiphase generator concept without a winding overhang. It gives an overview of the system and specifies the characteristics of the concept. Suggestions for the design of the short-circuit ring are included as well as feasible variants of a multiphase transformer to connect the multiphase generator to the grid. Additionally, the behaviour of the system at rated operation is presented.
