Estudo de correntes de inrush e ferroressonância em transformadores monofásicos.

Abstract

When occur voltage changes, current or frequency that results in failure or bad operation of the power grid, comes into question the term "power quality". The worsening problems is caused by several factors affecting system performance in stationary and transient regimes. In this work, we present the study comprising a computer simulation of the inrush and ferroresonance phenomena, based on the models of Jiles-Atherton. It is shown the behavior of the voltage curves, current, hysteresis, this type of ferroresonance and results of the application of techniques for mitigation of these effects.
