A Comprehensive Review on Fault Current Limiter for Power Network

Abstract

Existing Power system has a major role indistributed generation. As the power systems are arriving more and more complicated they are becoming an incorporation of some power electronic devices. Limiting the fault current is important as the protection of power electronic devices as well as the reliability of system is depending upon it. This paper is consisting of the current limiting techniques which are used to suppress the excess magnitude of fault current during fault. Various types of fault current limiters are used in the power system. The focus here is on superconducting fault current limiting reactors. SFCL is a device which overcomes the problems due to the increased fault current levels. In this paper operating principle and structure of various power current limiters is explained thoroughly.
