Abstract

Ferroresonance is type of resonance in electric circuit happens when a nonlinear inductance from the source is connected in series with capacitor, and the circuit is subjected to a disturbance such as opening of switch or lightning. The occurrence will result in damaging the component connected with the system and hence reduce the quality of the power transmission. In order to prevent this from happened and affected the power quality of electrical equipment. The ferroresonance suppression circuit (FSC) will be applied. FSC that installed on secondary transformer used for prevent the severely damage to electrical equipment in voltage transformer. The circuit design for FSC using active filter to eliminate the harmonic disturbance from nonlinear load. Most of the disturbance is produced by ferroresonance phenomenon. The main purpose of this project is to design and analyze active filter for FSC which can be used to mitigate the ferroresonance phenomenon. The design and simulation of this project will use Power System Computer Aided Design (PSCAD). The simulation analyze based on the voltage reading of the transformer. Active shunt filter is used as the mitigation method in solving the ferroresonance phenomenon.
