“…However, for 2D systems with J constrained to flow in only one direction reliable solutions for the electromagnetic problem can be achieved, whilst the heat transfer problem is solved via the transient conduction equation. This strategy has been used for describing the electro-thermal properties of single coated conductors [52] - [53], stacks of 2G HTS tapes [54], and 2G HTS coils [55], as active elements of the SFCL. For the sake of simplicity, COMSOL also allows the 1D modelling of SFCL, with differences between the theory and experimental measurements of about 20-40% in 2G HTS tapes, decreasing for the case of MgB2/metal conductors [56].…”

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.

“…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.

This paper proposes a new technique to develop an accurate multiphysics parametric model for microwave components to speed up the multiphysics modeling process. In the proposed technique, the artificial neural networks (ANNs) and pole/residue based transfer function are incorporated to represent the highly non-linear relationships between electromagnetic centric (EM-centric) multiphysics behaviors and multiphysics geometrical/non-geometrical design parameters. Vector fitting technique is utilized to obtain the poles/residues of the transfer function for each multiphysics sample. Since the relationship between multiphysics design parameters and the pole/residues of the transfer function is non-linear and unknown, two mapping functions are proposed to establish the mathematical links between the multiphysics design parameters and poles/residues. Parallel multiphysics data generation is proposed to generate the training and testing data for establishing the proposed multiphysics parametric model. A two stage training algorithm is proposed to guide the multiphysics training process. Once an accurate overall model is developed, it can be used to provide accurate and fast prediction of the multiphysics behavior of microwave components with geometrical and non-geometrical parameters as variables, and further can be used in the high level design. Compared with the existing multiphysics modeling methods, the proposed technique can achieve better model accuracy with high efficiency. The proposed technique provides an accurate and efficient methodology even when the coarse model or empirical model is unavailable. Two microwave examples are used to illustrate the validity of the proposed multiphysics parametric modeling technique. INDEX TERMS Artificial neural networks, multiphysics, parametric modeling, parallel computation, transfer function.
