Abstract

The model equivalent circuit is identified. From motor manufacturers test report, parameters R_a, and X_m are calculated. The rotor parameters X12, X1, X2 ,R1, R2 and stator parameter X_a are determined by using direct search optimization method. The starting and running performance values are calculated and compared with available values. From estimated parameters, the transient and sub-transient reactance and time constants are calculated using Laplace operational inductance.
