Wound-rotor induction machine model with saturation and high-frequency effects

This paper sets forth a novel model of a wound-rotor induction machine, which incorporates magnetic saturation of the main flux path and high-frequency effects. The model's experimental parameterization procedure is described in detail. This consists of standstill frequency response tests, and a test for determining the machine's magnetizing characteristic and turns ratio. Time-domain simulations are used to highlight the capabilities of the proposed model, and to compare its predictions with those of a classical model at both transient and steady states.
