The main objective of this work is to simulate the behavior of superconducting fault current limiters (SFCLs) in the electric power grid. We investigate the transient behavior of SFCL devices when subjected to a fault current in a simple network. The simulated devices are a resistive SFCL and an air coil SFCL, both equipped with 2G HTS conductors. Simulations are performed in EMTP-ATP by means of a thermal-electrical analogy model. The limiting performance, voltages at buses, resistance, and the temperature rise of both devices are obtained. The results suggest that both SFCLs are able to protect the proposed network. Index Terms-ATP-EMTP, bus-tie, power grid, superconducting fault current limiter, transient simulations, YBCO 2G tapes.

“…In this study, the approach in designing an FCL is fundamentally different than in most literature works [1], [5], [8], [9], [11], [12], [15], [22]- [24]. Because the actions of circuit breakers effectively limit the NSFCL's runtime in fault conditions, the NSFCL only needs to handle the high-power stresses for a short time (typically 3-5 cycles, 50-100 ms for 50/60-Hz systems).…”

“…But besides the high material costs, superconductors require very low-temperature environment to maintain superconducting state. Even for high-temperature superconductors, the transition temperature is typically around 100 K (−279°F or −173°C) [8], [9]. This means extra cost for the refrigerating equipment and power losses for the cooling.…”

This paper proposes a nonsuperconducting fault current limiter (NSFCL) topology and control strategy. The switched impedance transformer-type NSFCL topology is optimized to protect against short transients and to work in conjunction with other fuses or circuit breakers, hence has the merits of being simple, low cost, and compact. A prototype has been designed and built for a three-phase 600-V R M S ,L −L system. It has been tested in a ULcertified high-power test lab with 5-A normal current and 100-kA potential fault current.Index Terms-Bridge rectifier, fault current limiters (FCLs), high-power faults.

Protection Principle for a DC Distribution System with a Resistive Superconductive Fault Current Limiter

et al. 2015

A DC distribution system, which is suitable for access to distributed power generation and DC loads, is one of the development directions in power systems. Furthermore, it could greatly improve the energy efficiency and reduce the loss of power transportation. The huge short circuit current is always a great threat to the safety of the components, especially the capacitors and diodes. A resistive superconductive fault current limiter (SFCL), which could respond quickly once a fault happens and limit the fault current to a relatively low level, becomes a good solution to this problem. In this paper, the operational principle of the resistive SFCL is introduced first, and then, the DC short-circuit fault characteristic of the DC distribution system with the SFCL is analyzed and the effectiveness of the SFCL verified. In order to realize the selectivity of the protection in the DC distribution system with SFCL, a new transient current protection principle based on Ip (the peak value of the current) and tp (the transient time that the current takes to reach its peak value) is proposed. Finally, a model of a 10-kV DC distribution system with an SFCL is established and simulated in PSCAD/METDC. Simulation results have demonstrated the validity of the analysis and protection principle.
