“…Multiobjective design methodologies and seamlessly integrated simulation toolboxes: metaheuristic and evolutionary strategies, such as GAs [105], have already been used to design SFCL devices by multiobjective optimisation addressing distinct design parameters while complying with technical and economic requirements [103,106]. One such methodology relies on representing the SFCL by a reluctance-like circuit, whose characteristics depend on several parameters of the limiter.…”

“…The designed schematic of the SI-SFCL, as depicted in Fig 7 , mainly consists of a primary copper coil (CPC) directly connected to the DC power system, a rectangular magnetic iron-core, and an excitation SC supplied by a DC bias current source [ 49 , 50 ]. Both the CPC and SC generate magnetic fields in opposing directions.…”

A saturated iron-core type superconducting fault current limiter (SI-SFCL) can effectively restrict the magnitude of the fault current and alleviate the strain on circuit breakers in DC power systems. Design of a superconducting coil (SC), which is one of the key tasks in the SI-SFCL design, requires guaranteeing a sufficient magnetic field, ensuring optimization of the shape and size, minimizing the wire cost, and satisfying the safety and stability of operation. Generally, finite element method (FEM) is used to calculate and evaluate the operating characteristics of SCs, from which it is possible to determine their optimal design parameters. When the coil is complex and large, the simulation time may range from hours to days, and if input parameters change even slightly, the simulations have to be redone from scratch. Recent advances in deep learning represent the ability to be effective for modeling and optimizing complex problems from training data or in real-time. In this paper, we presented a combination of the FEM simulation and deep Q-network (DQN) algorithm to optimize the SC design of a lab-scale SI-SFCL for a DC power system. The detailed design process and options for the SC of SI-SFCL were proposed. In order to analyze the characteristics related to the electromagnetic properties and operational features of the SC, a 3D FEM model was developed. Then, a DQN model was constructed and integrated with the FEM simulation for training and optimizing the design parameters of the SC in real-time. The obtained results of this study have the potential to effectively optimize the design parameters of large-scale SI-SFCL development for high-voltage DC power systems.

“…At present, the research on this type of SCFCL mainly lies in the structural optimisation, coil design, system simulation and so on. A design methodology that allows modelling and optimising reactive superconducting SCFCLs is presented in [59]. The methodology considers the characteristics of each constitutive element of the limiter while addressing utility requirements and power grid characteristics.…”

With the continuous expansion of power grid capacity, the problem of short‐circuit current exceeding the standard is becoming increasingly serious. Fault current limiter is a promising solution and is gradually becoming a research hotspot. In this study, fault current limiters are classified into four categories. And saturated‐core fault current limiters are emphatically introduced, including its working principle and comparison with the other three categories. Saturated core fault current limiters are divided into four branches according to the ways leading the core saturated. A comprehensive review of the research activities and emerging technologies of saturated‐core fault current limiters for AC power systems is presented in this study. The working principle and typical structure of DC‐biased‐, permanent‐magnet‐, superconducting‐ and hybrid‐type saturated‐core fault current limiters are introduced. The advantages and disadvantages of four types of saturated core fault current limiters are compared in detail from the aspects of current‐limiting performance, iron core size and DC magnetomotive force. Real grid application examples of some types of devices are presented, as well as new progress in the techniques, are covered and discussed in detail. One may find the content of this study helpful as a detailed literature review or as practical technical guidance.
