“…Due to the slight critical current differences between the several units, resistive SFCL faces difficulty in quenching simultaneously between the units; however, this problem can be solved with hybrid SFCL [81]. Hybrid SFCL is proposed for limiting fault current and improving dynamic performance of power system [80][81][82][83]. A hybrid type SFCL has a primary winding and several secondary windings as shown in Figure 6 [81].…”

Power systems are becoming more and more complex in nature due to the integration of several power electronic devices. Protection of such systems and augmentation of reliability as well as stability highly depend on limiting the fault currents. Several fault current limiters (FCLs) have been applied in power systems as they provide rapid and efficient fault current limitation. This paper presents a comprehensive literature review of the application of different types of FCLs in power systems. Applications of superconducting and non-superconducting FCLs are categorized as: (1) application in generation, transmission and distribution networks; (2) application in alternating current (AC)/direct current (DC) systems; (3) application in renewable energy resources integration; (4) application in distributed generation (DG); and (5) application for reliability, stability and fault ride through capability enhancement. Modeling, impact and control strategies of several FCLs in power systems are presented with practical implementation cases in different countries. Recommendations are provided to improve the performance of the FCLs in power systems with modification of its structures, optimal placement and proper control design. This review paper will be a good foundation for researchers working in power system stability issues and for industry to implement the ongoing research advancement in real systems.

“…The superconductor, which is the HTS, typically operates in three states-flux creep (superconducting state), flux flow, and resistive (normal) state-when the fault occurs. The thermal subsystem model of the HTS is described in [15]. To compute the resistance of the HTS, the electric field in each state must be determined, which can be described by exists when the electric field is less than or equal to the critical electric field of the superconducting coil.…”

“…On the other hand, the long recovery time of the high-temperature superconductors (HTS) cannot handle a reclosing criterion. To reduce the recovery time, a hybrid SFCL technique using a current-limiting resistor/reactor (CLR) as the fault-current-limiting device has been proposed in [15] for utilization in Korean power systems. This paper offers a hybrid SFCL design based on CLR reactance calculation for improving the fault ride-through capability of DFIG wind turbines, satisfying the grid code requirements of Ireland, Italy, Sweden, and Denmark.…”

This paper presents a new approach for the low voltage ride-through capability enhancement of doubly-fed induction generator (DFIG) wind farms using a hybrid superconducting fault current limiter (SFCL) of the first peak current limiting type, which has the advantage of a fast recovery time. A design for the hybrid SFCL, focusing on current limiting reactor (CLR) reactance calculation, is proposed in this paper to determine an appropriate value for the CLR reactance that satisfies the grid code requirements of the DFIG wind turbines. High-temperature superconductors (HTS) such as Bi-2212, YBCO, Bi-2223, Ti-2223, and Hg-1223 are investigated for use in the hybrid SFCL. The recovery time and first peak current reduction effectiveness are the criteria for selecting the HTS. In the proposed method, a during-fault voltage from the grid code requirement is used as an input parameter to compute the reactance of the CLR.Based on the results of the base-case simulations conducted on the DIgSILENT PowerFactory software, the Bi-2223 HTS with the first peak of fault current less than 4.5 kA and recovery time of 2.5 s is selected for adoption in the hybrid SFCL. The calculated results of the proposed method are compared with the simulation results of the hybrid SFCL, in terms of the DFIG wind turbine fault ride-through capability enhancement, to demonstrate that the performance of the proposed method satisfies the grid code requirements.
