Desing methodology of roebel stator bars for salients poles synchronous generators
Article Sidebar
Main Article Content
In present paper a comparison between three methodological approaches for the implementation of the Roebel transposition method for the design of the stator bars of the winding in great synchronous machines is presented. The revised methodologies are obtained from three different authors: Juan Corrales Martin, Karl Vogt, Aleksandr Abramov, J. Pyrhönen, T. Jokinen, and V. Hrabovcová. The methodologies were applied to the study case of a synchronous generator of 125MW located in the Salvajina Hydroelectric Plant and identified as Unit number 1, based on the information compiled from the description of the salient pole synchronous generator and the general study of its operation, specifically of the armature winding with methodology [1], to establish a methodology that allows sizing a Roebel-type bar that will serve for the development of future research as a guide for the study of other generators.
