Abstract: A core-saturated superconductive fault current limiter and a control method of the fault current limiter. The fault current limiter includes a superconductive magnet (2), a core (4), an AC winding (5), a cryostat system, a monitor system (7) and a DC control system (6). The output of the DC control system (6) is connected to the two terminals of the superconductive magnet (2). The DC control system (6) is also connected to the monitor system (7). The core (4) has an unequal section core structure. The control method includes: controlling the current which is flowing through the superconductive magnet (2) for limiting the fault current in the power net (1) in the case of a short circuit fault event.

Abstract: A superconducting cable with hybrid conductor unit is provided, which includes a cable former, a conductor unit, an adiabatic envelope, a dielectric layer, screening layer and protective encloser characterized in that the hybrid conductor unit is formed from a combination of superconductor layers, normal metal conductor layers, and superconductor-normal metal mixed layers. As compared with a typical superconductor cable having the same power transmission capacity, the hybrid superconductor cable has the following advantages: simplify the fabrication process; reduce the manufacturing cost; enhance the cable's mechanical strength and increase the cable's ability to withstand over flow current and quench. The hybrid superconductor cable lays the foundation for superconductor cable's industrialization.
