Double-fed three-phase induction machine abc model for simulation and control purposes

The aim of this paper is to develop a doubly-fed induction machine (DFIM) abc model suitable for the simulation of this machine in any system with control circuits and/or connections to thegrid by means of power electronics converters. The circuit-oriented approach has been chosen in order to represent the DFIM model as a rotating transformer. In fact, a class of universalmachine model has been built to be used with simple input electrical parameters such as stator and rotor resistances, self, leakage and mutual inductances. With the available model, it ispossible to simulate any kind of asymmetry in both stator and rotor sides with or without variations of the machine parameters. A specific wound-rotor induction machine model, using only resistances, inductances and controlled voltage sources, has been developed. The couplingeffects between stator and rotor has been taken into account usingan approach to represent stator-rotor mutual inductance. The performances of the model have been verified bycomparison between simulation and experimental results on a 0.09kW-220V/380V-50Hz-4 poles DFIM working in motoring mode at standstill, no-load and rated load conditions.
