The feasibility study on the combined equipment between micro-SMES and inductive/electronic type fault current limiter

The concept of the combined equipment between micro-SMES and inductive/electronic type FCL is proposed in this paper. Having the multifunction for a superconducting device, the new equipment can serve as the protective component for a dual power system. The specification of a testing model was determined and the transient performance was analyzed by Matlab software. The results show that the combined equipment is realizable for a dual power system application, where it has the major function of limiting fault current (FCL function) and the minor function of maintaining power fluctuation (SMES function).
