Ferroresonance simulations in radial systems using ATPDraw

Abstract

Fundamental parts of an electrical system are radial systems, which may be operating at different voltage levels, where an unwanted event such as ferroresonance is possible to occur. The conditions for the presence of a ferroresonance in an electrical system can present high overvoltages that can result in damage to critical equipment, high costs of corrective maintenance and plant shutdowns. These impacts mentioned justify the importance of analyzing, predicting and being able to establish strategies that avoid ferroresonance. In the present work simulations of radial feeders are shown where the ferroresonance event is presented as well as strategies to mitigate it by observing the behavior of voltage signals through simulations in the ATPDraw software.
