  Authors : N. Vijay Chand; V. Narendra Kumar


The excessive fault current is seriou problem to successful implementation of micro grids.. The superconducting fault current imiter(SPCL) is very essential for upcoming smart grids. In this work, a resistive type SFCL model was implemented. The developed SFCL works on depending on impedance. SFCL model utilized for to find impedance level of SFCL according to the fault current limitation requirements of different smart grid system. In addition, typical smart grid model including generation, transmission and distribution network with dispersed energy resource was mod-eled to determine the location and the performance of the SFCL. As for a dispersed energy resource, 10 MVA wind farm was con-sidered for the simulation. Three phase faults have been simulated at different locations in smart grid and the effect of the SFCL and its location on the wind farm fault current was evaluated. Conse-quently, the optimum arrangement of the SFCL location in Smart Grid with renewable resources has been proposed and its remark-able performance has been suggested.

This paper presented a feasibility analysis of positioning of the SFCL in rapidly changing modern power grid. A complete power system along with a micro grid (having a wind farm connected with the grid) was modeled and transient analysis for three-phase-to-ground faults at different locations of the grid were performed with SFCL installed at key locations of the grid. It has been observed that SFCL should not be installed directly at the substation or the branch network feeder. This placement of SFCL results in abnormal fault current contribution from the wind farm. Also multiple SFCLs in micro grid are inefficient both in performance and cost. The strategic location of SFCL in a power grid which limits all fault currents and has no negative effect on the DG source is the point of integration of the wind farm with the power grid.
