“…However, the pressure on the network to maintain everincreasing levels of supply and manage distributed generation mean that greater flexibility of network management and protection is needed. This has led to the development and installation of novel SFCLs on congested networks 8,9 in the UK. If SFCLs can be proven in the field as a cost-effective and reliable means of reducing maximum fault current, then there is a possibility that SFCLs might transfer to other applications where fault current limitation may provide significant benefits.…”

Electrically driven distributed propulsion has been presented as a possible solution to reduce aircraft noise and emissions, despite increasing global levels of air travel. In order to realise electrical propulsion, novel aircraft electrical systems are required. Since the electrical system must maintain security of power supply to the motors during flight, the protection devices employed on an electrical propulsion aircraft will form a crucial part of system design. However, electrical protection for complex aircraft electrical systems poses a number of challenges, particularly with regard to the weight, volume and efficiency constraints specific to aerospace applications. Furthermore, electrical systems will need to operate at higher power levels and incorporate new technologies, many of which are unproven at altitude and in the harsh aircraft environment. Therefore, today's commercially available aerospace protection technologies are likely to require significant development before they can be considered as part of a fault management strategy for a next generation aircraft. By mapping the protection device trade space based on published literature to date, the discrepancy between the current status of protection devices and the target specifications can be identified for a given time frame. This paper will describe a process of electrical network design that is driven by the protection system requirements, incorporates key technology constraints and analyses the protection device trade space to derive feasible fault management strategies.

“…Using the same bulk material, but cut into monofilar coils, the first commercial medium voltage SFCLs were released in 2009 by Nexans SuperConductors GmbH for two customers [8]: Applied Superconductor Limited in UK, and Vattenfall in Germany. Most recently, a SFCL with a rated power of 4.4 MVA (11 kV,0.4 kA) was installed in the UK earlier 2012, and it has been operating since middle 2013 [9]. Also, a novel concept of magnetic field assisted quench propagation was developed in order to overcome the difficulties on the scaling of the bifilar concept to high voltages, with a successful proofof-concept test achieved in the United States in 2005 [10].…”

Abstract-In recent years, major industrialized countries have began to be concerned about the need for developing strategies on the integration and protection of the growing power capacity of renewable source energies, attracting back their interest on the development and understanding of superconducting fault current limiters (SFCL). The reasons for this are simple: a SFCL may offer a rapid, reliable and effective current limitation, with zero impedance during normal operation, and an automatic recovery after the fault. Nowadays, most of the R&D projects have turned towards to the study of the resistive type SFCL due to their potential to be small, and the likely decrease in price of 2G coated conductors. Thus, in this paper we provide an updated review on the state of the art of resistive type SFCL, emphasizing on the different approaches for the numerical modelling of their local physical properties, as well as on the already tested experimental concepts. Comparison between the properties and characteristics of different resistive-type SFCL using different superconducting materials is presented.
