Special Issue Information

Dear Colleagues,

With the rapid development of high-temperature superconducting (HTS) materials, superconducting power applications have attracted increasing attention in the power industry, particularly for electrical systems with a high proportion of renewable energies. Superconducting fault current limiters (SFCLs) have obtained many successful engineering projects around the world and can be regarded as an extremely potential solution to assist electrical systems against fault inrushes.

The purpose of this Special Issue is to provide a platform for presenting the latest research results on superconducting fault current limiters. This Special Issue covers but is not limited to theories, technologies, applications, and field experience of SFCLs. We seek original research papers on theoretical, methodological, and empirical studies, as well as review papers that provide a critical overview on the state of the art of technologies. This Special Issue is open to all types of SFCLs, such as resistive type, inductive type, flux-coupling type, and saturated core type. It is also open to all voltage classes of power system protection with SFCLs, such as hybrid AC–DC power distribution networks and HVDC transmission networks. We kindly welcome original, high-quality contributions that are not yet published or that are not currently under review by other journals or peer-reviewed conferences.

In order to solve the problem of excessive short-circuit current in the present power system, a fault current limiter has become a new type of power device with high demand and is one of the current research hotspots. The flux-coupling type superconducting fault current limiter (FC-SFCL) generates a current-limiting impedance through decoupling superconducting parallel inductance based on the circuit breakers’ fractional interruption. The principle is simple, and the impedance is low during normal operation. It can directly use the existing circuit breaker to open a short circuit that is much higher than its own breaking capacity. Thus, it can be used for large-capacity fault current limiting and effective failure breaking. This paper focused on exploring and studying the implementation scheme of practical products of FC-SFCL. Considering that the quenched-type parallel inductance can limit the first peak value of the fault current, a quenched-type improvement scheme was proposed. Then, an electromagnetic design method based on the simplified calculation of the number of parallel tapes was proposed, which simplified the design process and reduced the design difficulty of the quenched FC-SFCL. Taking a 10 kV/500 A/5 kA quenched prototype as an example, its electromagnetic design was completed, and the performances of the non-quenched and quenched schemes were compared. The results showed that, compared to the non-quenched structure, the technical economics of the quenched one were more prominent, and it can be used preferentially for engineering prototypes. This study about the scheme of the quenched FC-SFCL and its electromagnetic design method is useful for promoting the implementation of the current limiter engineering prototype. Full article

Numerical calculations of parameters of an electrical power network where an HTS fuse is used as a fault current limiting device have been done. The calculations were performed for networks containing different types of HTS cables as well. The design of HTS fuse was developed based on the numerical calculation for the network-rated parameters considering the special types 2G HTS tape characteristics. The distinctive feature of these tapes is the minimal thickness (about 30 µm) of the substrate at the critical current 450–600 A. The tests were performed at a voltage of 1 kV and demonstrated the ability of circuit breaking at fault currents about 3–4 kA. A comparison of experimental results with the calculations allows us to conclude that the HTS fuse of this design can operate as a fault current limiting device in electrical power networks at various rated voltage levels.
