A Novel 110KV Fault Current Limiter for Improving The Reliability of A Substation

Abstract

In this paper, superconducting fault current limiter (FCL) is used as a novel technology for reducing the high fault currents and enhancing the security of 110kV substation . The model of 110kV substation is developed using the M at l a b simulation program. The model is used to study at normal condition and short circuit analysis with the Matlab software. In the model of the FCL its major components, operation control algorithm, sequence of events and fault detection techniques are developed. The reduction of the fault currents are studied at the buses of suspected high fault currents by installing the FCL. The waveform obtained is for with and without FCL and comparison is done for the result. The transmission line is considered for the fault analysis using Fault Current Limiter with and without. The simulation results obtained have demonstrated the effectiveness of FCL in improving the system performance, reliability and security.
