Implementation of optimized Parallel-LC-Resonance Type Fault Current Limiter

Abstract

Fault current Limiter (FCL) supplies low rate solutions tosubstitute conventional defense devices. This protects other equipment onthe process from getting damaged by way of immoderate fault currents.FCLraised to becomeexcellent alternative to scale down rankings of circuit breakers and may limit theelectromagnetic stress in related equipments. In this paper a brand new parallel resonanceFault current Limiter (FCL) has been modified in a waythat may sustain the magnitude of fault present and manageit in a favored worth. The operation is based on making use ofparallel L&C resonance circuit with a resistor that reducestransient time and a pair of thyristors for controlling thevalue of fault current. Additionally, the proposed FCL doesnow not use a superconducting inductor which has highbuilding cost. Analytical evaluation for this structure ispresented in detail, and simulation outcome are acquired tovalidate the effectiveness of this structure. The simulationresults are obtained utilizing MATLAB/SIMULINK.
