Novel Model of Circuit Breaker for 275kv Substation

Hamid Radmanesh and Amir Heidary

Abstract—In this paper, at first non-conventional ferroresonance phenomenon is introduced, then various types of ferroresonance in a potential transformer is simulated. So, effect of circuit breaker shunt resistance on controlling chaotic ferroresonance in a potential transformer has been studied, it is shows that for some parameter value this resistance cannot clamp the ferroresonance overvoltages in potential transformers. Finally effect of neutral earth resistance on the controlling these oscillations has been investigated. The proposed approach was implemented using MATLAB, and results are presented. It is concluded that this resistance generally can cause ferroresonance decreasing. For confirmation this aspect simulation has been done on a one phase potential transformer rated 100VA, 275kV. The simulation results show that considering the neutral earth resistance on the system configuration, shows a great controlling effect on ferroresonance nonlinear overvoltages.

Index Terms—Ferroresonance oscillation, stabilizing, chaos control, potential transformer, circuit breaker shunt resistance.
