“…The worst case is the LCB failure backup sequence. As observed in (7), as in [15], the limitation time, t lim , is an important sizing parameter of the SFCL. The value of t lim reaches a maximum of 50 ms during the LCB failure backup sequence.…”

“…If I sfcl > 0.75 − I c ( T 0 ), a local quench can cause a local overheating known as hot spot, destructive for the SFCL. The length, l sfcl , is set at 2.32 km following the sizing procedure proposed in [15], where a comprehensive explanation of the optimum sizing of superconducting tapes regarding costs, thermal stability and electrical behaviour is given. From this sizing, one can infer that the limitation current ( I lim ) will always be equal or lower than the critical current I c ( T 0 ).…”

A cluster of distributed generation (DG) is a Microgrid (MG) and load which acts as a heavy load or source in the context of actual grid. The sudden gust in the microgrid causes rise in fault current which surpasses the shortcircuit limit of network equipment by microgrid connection and also the increase in penetration of DG into the grid, the fault current level is also increased simultaneously. In order to overcome this problem, fault current limiter (FCL) could be arranged between the main network and microgrid. There are different types of FCLs, which have various designs and are made of various superconducting materials. Superconducting Fault Current Limiter (SFCL) is revolutionary protective device which has the ability to lower the fault current level within the fault current first cycle. The application of the SFCL would not only reduce the burden on network devices, but also offers connection for the betterment of the power system reliability. SFCL's are broadly classified into three types: inductive, resistive and hybrid SFCL. In this paper, general characteristics of FCLs, the operating characteristics, current limiting capabilities of SFCL are introduced into a simplified microgrid model system which is finally allowed that SFCL could reasonably bring about the function of microgrid stability improvement and fault current suppression.

Abstract. This paper provides a theoretical basis for high voltage magnetization and low voltage constant current excitation. The design structure of DC excitation power supply is put forward. As a controlled rectifier device, the 6RA70 is the core control unit of the superconducting fault current limiter. The problem that DC excitation power supply is difficult to control under high voltage and large current is effectively solved. The requirements of high voltage magnetization and constant current excitation control are expounded, and the switching methods between two states are described. PLC is used to establish a digital control system for networks. This paper provides a reference for the operation of superconducting fault current limiter.
