Abstract
In this work, an overview of available papers andcontributors to this area is provided, at first ferroresonancephenomenon is introduced and then various type offerroresonance in a voltage transformer is simulated. Effect ofneutral earth resistance on controlling oscillations has beenstudied. The proposed approach was implemented usingMATLAB, and results are presented. It is expected that thisresistance generally can cause ferroresonance ‘dropout'. Themagnetization characteristic of the transformer is modeled by asingle-value two-term polynomial with q=7. The simulationresults show connecting the neutral earth resistance on thesystem configuration causes a great controlling effect onferroresonance overvoltages. Significant effect on the onset ofchaos, the range of parameter values that may lead to chaosalong with ferroresonance overvoltages has been obtained andpresented.
