Double-fed Induction Machine Dynamic Modeling using Winding Function Approach

This paper describe dynamic model of double-fed induction machine in natural frame of reference. Winding function approach using for inductance calculations, take into account all MMF space harmonics simultaneously, what make this model appropriate for motor (generator) current signature analysis. Presented results from numerical experiment where double-fed induction machine have been analyzed in motoring and generating sub or super synchronous regime, illustrate the power of the model.
