Abstract :
The 2-D nonlinear sinusoidal electromagnetic fields of a 125 MW turbogenerator under synchronous operation are investigated. The magnetic field distribution and operational impedances at various slips with field winding short-circuited are obtained. Results are compared with the linear case and some conclusions on the saturated parameter are given
