A Novel Approach to Incorporate the Main Flux Saturation Effect in a Three-phase Induction Machine during Motoring and Plugging

  Abstract—In this paper, a new model has been proposed for the transient study of a three phase induction motor, especially for motoring and plugging operation. The ensuing behavior of the machine is predicted by d-q axis based model using MATLAB/SIMULINK environment. Instantaneous value based saturation curve in place of conventional saturation curve has been used to account the saturation in the transient modeling of induction machine. Simulated results as obtained using proposed model are compared with experimental results on the two test machines. A close agreement between the simulated and experimental results proves the validity of proposed modeling.
