Current Limiter

<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>

Surge Current

Owing to the scale of power distribution system’s continuously expanding, the closing loop operation is usually needed to meet the demand for the reliability of power supply. However, during the course of this operation, a larger AC surge current with 4~5 times of normal value will be induced, and the surge current can cause the equipped over-current protection take action incorrectly. In this paper, a hybrid type superconducting fault current limiter (SFCL) is suggested to installing into the distribution system, which will take action to inhibit the closing-loop transient surge current by using current-limiting impedance during the transient process. Furthermore, the simulation model of a typical distribution network with the hybrid type SFCL is built through PSCAD/EMTDC software. From the simulation results, it is verified that the suggested hybrid type SFCL can obviously reduce the surge current and improve the power system’s operational stability.
