Introduction of Distributed Energy Sources (DES) is the highest change happening to the distribution network. This paper describes different types of current limiting methods which reduce the magnitude of the fault current. The interconnected distributed energy sources to the conventional grid improves the power generation capacity of the power system but also increases the magnitude of fault current which cannot tolerate by the short-circuit ratings of the circuit breaker, relays, isolator etc. This paper reviews on the innovative electric equipment i.e. Superconducting Fault Current Limiter (SFCL), which reduces fault current magnitude in first cycle of fault current. Keywords: Distributed Energy Sources, Fault current, Superconducting Fault Current Limiter (SFCL), Protection Equipment.

As one of the most applicable to high-voltage network superconducting fault current limiterSCFCL(saturated core superconducting fault current limiter) ,which use of core saturation properties can be achieved the current-limiting function without delay ,will be the most widely applied in the future,By analyzing the working principle of SCFCL,this paper use of PSCAD and finite element analysis software Ansoft to build the 500kV\/3150A grade SCFCL model and accurate calculation coil self-inductance and mutual inductance, the harmonic of each size and analyzed its Impedance characteristic on the different external parameters,The results show that SCFCL has a excellent performance for high voltage power network short-circuit current limitation, and provides important reference for design.

<p>Superconducting fault-current limiters (SFCLs) have been the subject of research and development for many years and offer an attractive solution to the problem of rising fault levels in electrical distribution systems.  SFCLs can greatly reduce fault currents and the damage at the point of fault, and help improve the stability of a power system. Superconducting fault-current limiters (SFCL) provide a  new efficient approach to the reliable handling of such  faults.(SCFLs) can be used for various nominal voltages and currents, and can  be  adapted  to  particular  limiting  characteristics  in  case  of  short  circuits. In this project, dc resistive type superconducting fault current limiter (SFCL) is presented. This SFCL is designed for the HVDC system.  Uniform current and voltage sharing among the SFCL modules can be observed through contact resistance tests, dc flow-through tests, and ac flow-through tests. Results of tests show that each limiting module has good uniformity in higher current system. The proposed concept can be implemented using renewable energy sources. The results are presented by using Matlab/simulink platform.</p>

Recently, a lot of interesting research has been conducted to solve the fault current problem of the DC system. In long-distance transmission, DC transmission is more economical than AC transmission. The connection of power grids with a DC system can also better control the power flow and provide high stability. However, the control of the fault current in a DC system is more difficult to handle than in an AC system because the DC system does not make a zero point, unlike the AC system. In addition, there is a disadvantage, in that an arc occurs when a circuit breaker operates. In this paper, a new type of DC superconducting fault current limiter (SFCL) is proposed. This new type of SFCL is composed of two superconducting elements, a current limiting resistor/reactor (CLR), and a transformer. With the proposed SFCL, the DC fault current limiting experiments were performed and the DC fault current limiting characteristics of this SFCL due to the component of the CLR were analyzed.
