Abstract
This paper investigates the saturable transformer from modeling and control point of view. After implementing the Simulink model of the three phase transformer simulation of a three phase, two-winding transformer is used to examine the transformer under two operating conditions. The first is the secondary terminal short circuited and the second is the secondary terminals connected to a non-unity power factor load to verify the results obtained with those predicted from any analysis using the equivalent circuit. The graphical user interface is used for modeling transformer parameters, obtaining the results, check the stability of the control system, the settling time, the Bode plot, Nyquist and Nicols chart finally recording all currents, voltages and phase shift between them in the steady state condition, initial values of states variables for the nonlinear circuit parameters.
