Transient operation modeling of induction machine using standstill frequency response test

The mathematical models of the induction machine (IM) developed on the basis of the experimental frequency-response characteristics at standstill condition (SSFR) are proposed in this paper. At zero speed the transfer function of (IM) is used to obtain an exact linear parametric model. The latter ones are recommended for investigating the transient processes occurring at connections of (IM) to the electrical system. The identication of the equivalent circuit and its validation are carried out experimentally for a 0.25-kW (IM).
