Optimal Positioning of Superconducting Fault Current Limiters for the Smart Grid Application Using Simulink

Vasireddy Anvesh, Dr. M. VenuGopala Rao

In this paper, an application of superconducting fault current limiter (SFCL) is proposed to limit the fault current that occurs in power system, SFCL is a device that uses superconductors to instantaneously limit or reduce unanticipated electrical surges that may occur on utility distribution and transmission networks. At the time of fault occurs in the line, a large surge of power can be sent through the grid resulting in a fault. These faults can result in damage to expensive grid connected devices. SFCL's eliminate or greatly reduce the financial burden on the utilities by reducing the wear on circuit breakers and protecting other expensive equipment. Utilities can reduce or eliminate the cost of circuit breakers and fuses by installing SFCL. As for a dispersed energy source, 10 MVA wind farm with three units connected and the total was simulated. 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. Three wind farms were considered and their performance is also evaluated. Consequently, the optimum arrangement of the SFCL location in Smart Grid with renewable resources has been proposed and its remarkable performance has been suggested.
