Reducing Chaotic Oscillations in Potential Transformers

Hamid Radmanesh

Abstract—In this work, an overview of available papers and contributors to this area is provided, at first ferroresonance phenomenon is introduced and then various type of ferroresonance in a voltage transformer is simulated. Effect of neutral earth resistance on controlling oscillations has been studied. The proposed approach was implemented using MATLAB, and results are presented. It is expected that this resistance generally can cause ferroresonance ‘dropout'. The magnetization characteristic of the transformer is modeled by a single-value two-term polynomial with q=7. The simulation results show connecting the neutral earth resistance on the system configuration causes a great controlling effect on ferroresonance overvoltages. Significant effect on the onset of chaos, the range of parameter values that may lead to chaos along with ferroresonance overvoltages has been obtained and presented.

Index Terms—Ferroresonance oscillation, stabilizing, chaos control, potential transformer, neutral earth resistance.
