Parametric identification of fractional Park´s model: Modal approach

This paper presents a fractional identification technique for rotor skin effects in asynchronous machines Squirrel Cage. Therefore, to give a well comprehension to this identification technique, this paper presents first the diffusive phenomena in the rotor bars and the method for modelling the induction machine: modal approach. Next, the method allowing the estimation of the Park model of induction machine with fractional impedance.
