Description
Quench protection is one critical problem for superconductor magnet applications. The most common way to deal with quench in magnets is to disconnect and quickly discharge the magnet to prevent damage. In this research a novel proposal concerning quench protection for an SMES wound using YBCO conductor is presented. The new method can provide high reliability of SMES magnet. Based on this research, the SMES magnet can still work during the magnet partial quench situation without damage by using additional electrical circuitry. The additional electrical circuit can partially isolate the quenching pancake coil in the SMES magnet from the remaining coils. After the quenched coil recovers from overheat the coil can be connected back to the SMES magnet using the proposed control method. The novel control method is designed in this research which can both make the SMES magnet constantly work during the quench and protect the SMES magnet from damage. In this paper, the new proposed SMES control circuit and the novel control method will be presented and the simulation performance will be shown at the end of the paper.
