Abstract
The DQ/dq model has been widely used to study single machine transients but it is difficult to use for multimachines during unbalanced faults when the effects of source impedance must be included. In this paper, a hybrid model (ABC/dq) of an induction motor is used in order to analyze the reclosing transients of several hundred critical motors in a refinery. These results are compared with the results from a reduced order model with a significant reduction in computational burden. The correlation is satisfactory
