Transformer Type Superconducting Fault Current Limiters for Further Developments in Smart Grid

Muhammed Haris.K | Sethulakshmi.S

Abstract: Continuous increase in electrical power demand has leading to an increase in power grid size. The Distribution Generation is used to supply extra power to the grid but it increases the abnormal operation and fault current in the grid. this fault current level may cross the rated value of conventional circuit breakers and these circuit breakers allow to pass initial fault current cycles before getting activated in this case Superconducting fault current limiter can use successfully for reduce fault current including first cycles. As more reforms continue in the grid, it creates difference in fault current level. A Transformer type SFCL with Two Non-Isolated Secondary Windings is capable to change the limiting value of the fault current by changing of turns ratio between two windings in secondary side. Resistive type is the simplest form of SFCL having constant critical value. it possible to found feasible locations of these SFCLS in a power grid through a test. In this paper, Transformer Type SFCL placed instead of resistive SFCL in optimal positions to get advantages of both types of SFCLs motioned. This is done by using a power system model created by MATLAB/Simulink software. A wind farm as DG and artificial faults are included.
