Abstract
The paper describes a unified loss model development of a converter machine system such that steady state loss characteristics and the dynamic behavior of both machine and converter are accurately represented in the model. (NOTE: A reliable and reasonably accurate loss model of a converter induction machine system is extremely important for performance prediction of variable speed drive.) Machine electrical losses (e.g,, stator and rotor copper loss, core loss, and stray loss) are considered for both fundamental and harmonic frequencies. Also considered are the skin effect on rotor resistance, temperature effect on both stator and rotor resistances, magnetizing inductance saturation, and friction and windage loss. All the above features are incorporated in synchronously totaling frame dynamic D-Q equivalent circuits.
