The dq model has been widely used to study single machine transients but it is difficult to use for multimachines during unbalanced faults when the effect of source impedance is taken into account. In this paper, a hybrid model (ABC/dq) of an induction motor has been used in order to analyze multimachines connected to the same bus. In this model, the algorithm is simpler and applicable for the analysis of a motor drive connected to the same bus with the induction motors. (C) 1997 Published by Elsevier Science S.A.
