An investigantion on Windings in New Generation of Synchronous Generators Based on XLPE Cable Known as Powerformers

Nowadays cable wound synchronous generators known as powerformers has been applied in modern power plants. Winding of them is so different compared to conventional winding used in customary synchronousgenerators. In this paper, the winding of them has been investigated and two appropriate wiring for armature winding has been presented. Then the advantages and disadvantages of them have been studied and one of them has been suggested. Finally analysis and simulation of a sample powerformer that used introduced wiring, based on finite element method has been done. The obtained results show the accuracy of claim
