Asynchronous Generator Non-Linear Mathematical Model in Simulation of Transient State

— in the paper a non-linear circuital mathematical model of a synchronous generator is presented. This model takes into consideration saturation effects in magnetic cores and phenomenon of eddy currents induced in solid parts of a rotor. The methodology for the determination of the model parameter set is given, using the finite element method. Simulation investigations are carried out for the 200 MW turbogenerator to examine the effects of magnetic circuit Saturation and the ways o
