Anurag.G, Sudhagar.V

In this paper the effect of various types of fault current limiters installed in a radial power distribution on the fault current and voltage distortion are analyzed and assessed. The distribution system will be operated under the influence of various types of fault. In this case, the voltage drop (sag) and overvoltage (swell) are severe because of the increased fault current when a fault occurs. The effect of various FCL on the fault current and the voltage distortion are analyzed by its connection in the radial power distribution system. First, resistive type superconducting fault current limiter, solid state fault current limiter and hybrid fault current limiters are designed using PSCAD/EMTDC. Next, a radial power distribution system is designed and the performances of various fault current limiters are analyzed in the basis of fault current limitation and reduction the voltage distortion. The result of SFCL is being analyzed with the result of solid-state and hybrid fault current limiters.
