Abstract

This paper presents a case study, carried out on behalf of National Grid, regarding the likelihood for sustained fundamental frequency ferroresonance on a particular circuit configuration. The study considered a complex arrangement including a mesh corner substation connected by overhead line to a transformer feeder. The study investigated the effectiveness of mitigation to quench the intended ferroresonance by switching-in a 60 MVA shunt reactor which is connected at the 13 kV tertiary winding. The modeling work has been carried out using the generally available ATP software.
