High voltage direct current (HVDC) circuit breakers are a key technology to enable fault management for multi terminal DC (MTDC) networks. DC circuit breakers using superconductors for current limiting have been proposed previously and experimentally tested at low voltage levels. Superconductor materials are ideal for DC networks: they do not incur losses operating with pure DC current. This paper will focus on the interface between the superconductor element and the other elements of the breaker, i.e., the mechanical switch and semiconductor elements. A 10 kV DC circuit breaker will be developed based on the optimized interface and control strategy.

“…Resistive SFCL is one kind of SFCL with the advantage of little conducting loss and power system impact. Fig.1 shows the schematic diagram of a resistive type superconducting fault current limiter [1].The superconducting coils (SC), which is immersed in liquid nitrogen, is in reverse winding in order to reduce self-inductance，connected with a vacuum interrupter (VI) and an electromagnetic repulsion plate (ERP) in series. Besides, a parallel reactor is connected with the SC branch in parallel.…”

The fault current in a large-scale power system is higher and difficult for conventional breakers to interrupt it. Resistive type high temperature superconducting fault current limiter (HTSFCL) can reduce fault current and achieve a fast operation which makes it a good supplement for conventional breakers. High speed repulsion mechanism driven by the short circuit current through the parallel reactor was used to drive the vacuum interrupter to cut off the current of superconductor side in 10~15ms to prevent it from destroy. According to this, we did some simulation about the key parameters which may influence its electromagnetic force, velocity and movement. Also, as the short circuit current was different, the velocity and movement of the repulsion mechanism varied a lot. Thus, proper parameters for the design of repulsion mechanism are very necessary for wide-range operation. According to this, we did some experiments to investigate the key parameters and came out with a prototype and succeeded. At last, interrupting test with recovery voltage was done to ensure its wide-range operation ability.

“…Because of expectations for this SFCL, various models for SFCLs with more effective fault-currentlimiting performance have been developed [1][2][3][4]. Among the developed SFCLs, the flux-lock-type SFCL using two magnetically-coupled coils has been reported to have its operating current and its limiting impedance adjusted by the winding direction and the inductance ratio of the two coils [4,5].…”

In this research, the current-limiting and recovery characteristics of a flux-lock-type superconducting fault current limiter (SFCL) with two adjustable operational currents were analyzed. The flux-lock-type SFCL with two adjustable operational currents, which consists of two magneticallycoupled coils, two high-TC superconducting (HTSC) modules connected in parallel, and an inserting resistance connected in series with one of the two HTSC modules, can limit the fault current with two operational currents by quench generation in either one HTSC module for a lower fault current or two HTSC modules for a higher fault current directly after the fault occurrence. To verify the current-limiting operation of this type SFCL, we constructed the simulated power distribution system protected by the SFCL, and we executed the short-circuit tests in the fault locations with both the lower and the higher fault currents. Through an analysis of the experimental results, effective current limiting operations of the flux-lock-type SFCL could be confirmed.
