Analysis and mitigation of ferroresonant oscillations in power system

Abstract

The aim of the paper is the review of analysis and mitigation of ferroresonant oscillations. The application of harmonic balance method and bifurcation theory was used to analyse a ferroresonant circuit. The derived closed-form solution is useful mathematical method to find turning points which define boundaries between safe (normal) and ferroresonant region as a function of system parameters. The influence of load on mitigation of ferroresonant oscillations was verified using Matlab/Simulink.
