Simulated Structure Of FCL For 3-Ø Unsymmetrical Fault In Power System
with increasing demand for the reliability and flexibility regarding the power system, it is necessary to detect the
fault very quickly and limit it as early as possible in a very less time. Most of the faults that occur on power systems are
unsymmetrical faults, which may consists of unsymmetrical faults through impedances, or open conductors. Unsymmetrical
faults occur as single line-to-ground faults, line-to-line faults, or double line-to-ground faults. This paper presents controlling
the magnitude of fault current by using fault current limiter with the help of controlled rectifier. So, simulation of
unsymmetrical faults and output waveforms besides that structure of fault current limiter in MAT-LAB is studied
