Contribution à la simulation et l’etude de la ferro-résonance dans les systèmes de transmission

Abstract

The main purpose of this dissertation of magister is to give a comprehensive literature review on ‘real case’ Ferroresonance phenomena having occurred at different voltage levels of power systems. Sensitivity studies on a single phase system are conducted. ATPDraw simulation was performed forenlightening complexity of Ferroresonance issue. Calculation formulas for certain characteristic points wereobtained to explain choices of parameters’ models contributing to the occurrence of such phenomenon. The accomplishment of a suitable simulation model allows the sensitivity studies to be performed to determine the degree of influence of various components of the ferroresonance phenomenon and modes,such as line length and transformer core loss.Suppressionmethods werediscussed in this work.
