| Abstract |
This paper presents an advanced model of the induction machine for accurate prediction of the fault current contribution due to line short circuits. The model is suitable for transient as well as for steady state operation analysis. The proposed model takes the skin effect in the rotor conductors and the effects of the leakage flux path saturation into account. It is experimentally verified using a six pole; 15kW squirrel cage induction machine. Measurements of a start, a three phase short circuit and a locked rotor test are compared with simulations, which show excellent agreements. |
