Abstract

This paper presents the application of Superconducting fault current limiters (SFCL) for smart grids in order to reduce possible effect of abnormal fault current. Increased demand results in increased generation capacity in power systems which has lead to increased fault current. At present several conventional protective devices are installed to reduce fault currents in electrical power systems. Predominantly used is circuit breaker which gets tripped off after two to three cycles of fault current by over-current protection relay. Thus they have a response delay of initial two to three cycles before getting activated. SFCL is an innovative electrical equipment which is capable of reducing fault current within first cycle itself and thus providing improved transient stability. In this paper the performance of SFCL for a three phase system is tested using simulink tool and the results are analyzed during both presence and absence of SFCL.
