  With advancement in design and analysis of electro-mechanical and
electromagnetic devices, the modelling of magnetic saturation of a synchronous
generator has emerged to be a subject of interest in number of publications.
Most of the existing electrical machine modelling methods does ignore the
saturation effect for simplicity. On the other hand, who incorporate saturation
effect, are dealing with complex computation of coefficients which involves
tedious curve fitting techniques like non-linear regression, least-squares.
This paper presents the novel method of modelling of the self-excited
synchronous generator along with magnetizing characteristics with ease and good
accuracy which is inspired from Froelichs equation. The proposed mathematical
model is implemented in simulation environment and validated the results with a
practical three phase self-excited synchronous generator in which saturation
plays a vital role.
