Abstract :
Ferroresonance is a nonlinear oscillatory phenomenon, which occurs in capacitively coupled transformers under certain conditions in a power system. The magnetizing branch of the transformer at no-load is modeled by nonlinear equation. The coupling capacitances are treated as parameters and different numerical simulations of ferroresonance are performed. The power spectral density and phase plane analyses are conducted on ferroresonance over-voltage generated across transformer to identify the modes of ferroresonance.
