“…In 2018, Baferani et al 16 provided the design for a novel three‐phase SISFCL that greatly reduces the volume of the core material and thereby the manufacturing cost. The new model is analysed using COMSOL Multiphysics software and was concluded to provide satisfactory current suppression while reducing the overall voltage drop across the device, reducing its footprint in the network.…”

Short-circuit faults are the most commonly occurring faults in an electrical power system. Traditionally, circuit breakers, fuses or similar protective devices are used to safeguard sensitive equipment from these faults by disconnecting the supply. An alternative approach for protection against shortcircuit faults is using fault current limiters (FCL), which suppress the large magnitude currents created by the fault to manageable values. This fault limiting action not only prevents damage to delicate equipment but also aids in providing uninterrupted power supply to the consumers. A promising FCL design is the saturated iron-core superconducting fault current limiter (SISFCL), which uses the property of its ferromagnetic core to suppress high-magnitude currents. In this paper, the performance of an open-core type three-phase SISFCL is analysed in response to variation of three model parameters. The parametric analysis is performed on the SISFCL under the effects of a symmetric-type three line to ground (LLLG) fault and an asymmetric-type single line to ground (SLG) fault. A finite-element modelling (FEM) approach is used in the design and simulation of the model in ANSYS Maxwell software. Following the parametric analysis, an optimization of the design of the SISFCL is performed using the Quasi-Newton Gradient Search method, in order to improve its performance against both LLLG and SLG faults.

“…There are various types of SFCLs, which generally can beclassified into resistive and inductive types [28,29]. Each type of SFCL has its merits and demerits.The resistive type SFCL isused more due to its compact size and simple principle of operation than inductive type SFCL [30][31][32]. The physical property of the resistive type SFCL is based on the E-J characteristic of the high temprature superconductor (HTS) and its dependence on temperature (T).…”

In this paper, the combined superconducting fault current limiter (SFCL) and STATCOM are used to improve transient stability and low-voltage ride-through (LVRT) capability of the wind turbine generation system (WTGS). The SFCL absorbs the accelerating energy of the generator, and therefore, improves the WTGS transient stability. Also, STATCOM helps the restore connecting point voltage to improve LVRT capability by reactive power compensation (RPC) after fault clearing. The optimization problem of SFCL resistance and STATCOM capacity is formulated based on the transient stability and LVRT capability of WTGS. The Simulation study shows the superior improving LVRT capability of combined SFCL and STATCOM over individual SFCL or STATCOM. Also, the required capacity of STATCOM for RPC is significantly reduced. PSCAD/EMTDC software (V4.2) is used for simulation.

“…Some simulation models for the SIC-SFCL based on the Finite Element Method (FEM) and in the Finite Element Analysis (FEA) are presented in the literature [10,18,[22][23][24][24][25][26][27]. These papers discuss the optimization of the iron-core, the applications of SIC-SFCL considering different types of short circuits, and the application of the SIC-SFCL in DC short circuits.…”

The short-circuit levels have increased considerably in transmission and distribution systems in the last years. Fault current limiter (FCL) devices are a potential solution to this problem. Among several FCL topologies, this group has good experience in the use of superconducting fault current limiters (SFCL) to reduce the electrical current during short-circuits. The literature also presents studies of the saturated iron core superconducting fault current limiter (SIC-SFCL) topology employing mathematical modeling and prototypes design. Some of them have shown promising results, including the construction of pilot prototypes in medium and high voltage substations. The SIC-SFCL simulation studies presented optimal topologies that reduce the amount of ferromagnetic material used in the core and represent well the behavior of this limiter. The finite element method and the finite element analysis are suitable to model the SIC-SFCL. However, a more detailed study focusing on the optimization of the DC bias superconducting coil of the SIC-SFCL has not been presented in the literature yet. In this context, this work proposes a multi-objective optimization method using the Nelder–Mead algorithm to find an optimal geometry for the superconducting coil. In this optimization, the objectives functions are: to maximize the critical current density in the high-temperature superconductor (HTS), minimize the voltage drop in the copper winding, minimize the current through the DC biased superconducting winding, and minimize the price of the HTS superconducting winding. Before implementing the multi-objective optimization algorithm, we have tested a non-superconducting saturated iron core prototype and used the results to validate the simulation models. After that, we have replaced the DC copper winding with an HTS coil in the simulations and initiate the optimization process. Results show that constructing the DC bias superconducting coil using the minimum possible fill factor might not be the best choice.
