Description
Summary:In this paper, the development of finite element-based phase variable model of three-phase wound rotor induction machine, in the presence of saturation and leakage inductances, is presented. The cross and mutual flux saturations are taken into account through the evaluation of inductances at different saturation levels. The leakage inductance was calculated from the suppression of evaluated inductances by respective flux and stored magnetic energies. In this model, the inductances are rotor position dependent. The simulation results show acceptable accuracy as compared to the full FE model but at a faster computation speed and acceptable memory requirements. These computational advantages make it possible for detailed simulation and for the creation of hardware in loop integrated drive simulations and development procedures.
