| Abstract |
This work proposes a model for induction machines in natural coordinates “abc”, developed consideringthe nonlinear characteristics of saturation. Traditionally, the models for the induction machine includingthis effect make use of linear transformations. However, the nonlinearity of saturation does not allowthe use of these transformations, giving invalid results. Flux linkage in each phase leads to the saturationcoefficient and this to the magnetic permeance. Hence, the saturation coefficient produces a newinductance in natural coordinates that considers the nonlinearity of saturation. The machine behavior iscomputed using a state variable model in natural coordinates described in the space vector frame. Theresults obtained by the proposed model give a better harmonic representation than the “dq0”models obtained by neglecting the magnetic hysteresis effect. A comparison between the proposed representation and the traditional one shows the advantages of the former. |
