Simulation of Nonlinear Transformer on Open and Short Circuit

Abstract:

How to simulate open and short circuit nonlinear transformer on the condition that excitation impedance is vary with voltageFited equations of excitation resistance and magnetizing reactance vs input voltage according to experimental data of no-load transformer.Calculated short circuit parameters .Solved directly phasor equations of electromotive force and magnetomotive force equilibrium according to the fited equations and short circuit parameters using Mathematica software. Simulation can simulate experiment of open and short circuit transformer dynamically,and also can draw no-load and short circuit characteristics curve accurately. Simulation results have verified the efficiency of the method. It will increase the efficiency of transformer experiment or design.
