High Voltage Generators,

Abstract

Abstract � high voltage synchronous generators known as powerformers, by changing stator configuration and their winding compared to conventional generator could generate fit voltage for connecting to transmission lines directly. Because of the innovation in their configuration and complication, fields and consequently reactances calculations would be so difficult by analytical formulas. In this article, numerical method based on finite element method has been used to calculate leakage, d axis and q axis reactances of a sample high voltage generator. Finally a comparison has been made between the results calculated by numerical analysis as well as analytical formulas. 1
