Abstract

The electromagnetic modelling of existing large hydro generator is the main focus of this paper. Electromagnetic commercial software was used where all geometrical parameters of the generator are taking into account such as: pole face geometry, air gap size, the slots geometry and pattern winding sequence. The approach used to model the machine and some simulation results are presented in this paper. The analysis of a 122.6 MVA, 60 poles, 13.8 kV generator is presented as a case study on how advanced electromagnetic numerical field simulations are employed to evaluate generator parameters and performances.
