“…Although short circuit tests can be conducted to demonstrate current limiting capability of any developed SFCL, a field test is necessary to validate the performance and reliability. SFCL practical installing issues and field tests have been reported [17,[46][47][48][118][119][120][121][122][123]. In many countries FCLs have been practically installed and field tests have been done with results and recommendations for further study.…”

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.

Superconducting fault current limiters (SFCLs) are important in improving the stability of electrical power systems. However, the existing resistive-type DC SFCL has a long recovery time, which cannot meet the requirements of power system auto-reclosure. Thus, it is necessary to investigate the methods of reducing recovery time of SFCLs. In the simulations on superconducting tapes, there is a lack of investigation about the effects of design factors of superconducting tapes and coils such as material, thickness, coil radius, coil winding method on recovery characteristics. The objective of this study is to obtain the effects of material and geometric properties of superconducting tapes and coils on recovery characteristics and obtain methods to reduce the recovery time. The recovery times under different conducting currents are also compared by simulations and experiments to verify simulation accuracy. The maximum error is below 40% and most of the cases have an error below 10%. Besides, by increasing tape thickness, the recovery time can be reduced by 22%. Tape materials and coil winding methods can be designed according to the auto-reclosure and current-limiting requirements of the power systems. The research provided directions for the design of superconducting tape and superconducting coil for resistive-type DC SFCLs.

This paper introduces a new scheme which uses a multifunctional superconducting device that can be used as an energy storage and as afault current limiter. It is denoted as superconducting magnetic energy storagefault current limiter (SMES-FCL) and is modeled as a number of pancakes. It is connected to a wind turbine power system via tertiary transformer and power converters. A complete control scheme is built to achieve effective power transfer between the superconducting coil and the power system during normal operation to smooth the wind turbine output power. The fault current limiting function is implemented using a new technique that inserts a few pancakes from the whole SMES coil into the main electrical system during the fault and isolates the remaining pancakes. The number of pancakes used to limit the fault is quenched and operates as a resistive fault current limiter. The whole system including the wind turbine, the SMES-FCL model and the interface circuit are implemented using PSCAD/EMTDC computer package. Also, the control scheme of SMES-FCL is built based on a feedback current signal to enable its operation into the two modes.
