This paper proposes a new model for aggregating a group of induction m
otors for system studies. The aggregation method developed here is bas
ed on the transformer-type variation of the equivalent circuit. A grou
ping criteria is used to classify homogeneous motors into different gr
oups. The validity of the proposed method is verified by comparing the
results obtained from the aggregate motor with the sum of the individ
ual motors. (C) 1997 Elsevier Science S.A.
