Book Description
This book presents a comprehensive survey of fault current limiters (FCLs) and their applications in power system to cope with the fault current. The book reviews characteristics, technologies, topologies, working principles, applications, and the interaction of FCLs with the power system. In the attempts to develop FCL with close to ideal attributes, academic researchers and companies offer the different configurations that are mostly classified into non-superconducting fault current limiters and superconducting fault current limiters (SFCLs). Both categories are included in this book, and therefore, it can serve as an excellent stepping-stone for senior and/or graduate students who are interested in knowing the reason of the increase in short circuit level in the power system, fault current limitation measures, benefits and drawbacks of the application of FCLs in power systems, the state-of-the-art of fault current limitation techniques, as well as recent advances in this area.

Book Description
Fault current levels in electrical systems are rising due to natural growth in demand, the increasing presence of distributed generation (DG), and increased network interconnection. This rising trend is expected to continue in the future. Marine vessel power systems are highly power-dense and are often safety-critical. Power system protection is increasingly challenging in these systems. Superconducting fault current limiters (SFCLs) offer an attractive solution to many of the issues faced. This thesis establishes and reviews the state of the art in resistive SFCL technology and application knowledge, and provides crucial research-based guidance for the adoption of resistive SFCLs in future power systems. The issues associated with the application of resistive SFCLs- including location, resistance rating, the recovery period, and interaction with protection systems are demonstrated. The relationship between several resistive SFCL design parameters is established using a generic analytical approach, hence providing a framework for validating SFCL designs. In particular, it is shown that a particular SFCL resistance rating leads to a peak in the superconductor energy dissipation, which generally should be avoided. It is proven that resistive SFCLs have an inverse current-time characteristic, i.e., they will operate in a time that inversely depends upon the initial fault current magnitude. This knowledge is critical for underpinning the operation of a novel protection scheme using multiple resistive SFCLs. The scheme offers several advantages: very fast-acting operation in response to faults anywhere on the system under study; maximum prospective fault currents are prevented from occurring, reducing the duty on circuit breakers; inherent, fast-acting backup; and communications is not required. It is shown that the scheme is suited to highly-interconnected systems with a high presence of DG. The scheme is readily applicable to the design of future utility and marine vessel power systems.

Book Description
Electrical power grids are the lifeline of technical infrastructure and fundamental for industry and modern lives. Fault Currents can disrupt the continuous supply of electrical energy, cause instable grid conditions and damage electrical equipment. The Air Coil Superconducting Fault Current Limiter (AC-SFCL) is a measure to effectively limit fault currents. The concept is investigated and proven experimentally by designing, building and successfully testing a 60 kV, 400 V, z = 6% demonstrator.

Book Description
The only one-stop reference to design, analysis, and manufacturing concepts for power devices utilizing HTS. High temperature superconductors (HTS) have been used for building many devices for electric grids worldwide and for large ship propulsion motors for the U.S. Navy. And yet, there has been no single source discussing theory and design issues relating to power applications of HTS—until now. This book provides design and analysis for various devices and includes examples of devices built over the last decade. Starting with a complete overview of HTS, the subsequent chapters are dedicated to specific devices: cooling and thermal insulation systems; rotating AC and DC machines; transformers; fault current limiters; power cables; and Maglev transport. As applicable, each chapter provides a history of the device, principles, configuration, design and design challenges, prototypes, and manufacturing issues, with each ending with a summary of the material covered. The design analysis and design examples provide critical insight for readers to successfully design their own devices. Original equipment manufacturer (OEM) designers, industry and utilities users, universities and defense services research groups, and senior/postgraduate engineering students and instructors will rely on this resource. "HTS technology reduces electric losses and increases the efficiency of power equipment. This book by Swarn Kalsi, a leading expert on the HTS subject, provides a survey of the HTS technology and the design rules, performance analyses, and manufacturing concepts for power application-related devices. It compares conventional and HTS technology approaches for device design and provides significant examples of devices utilizing the HTS technology today. The book is useful for a broad spectrum of professionals worldwide: students, teaching staff, and OEM designers as well as users in industry and electric utilities." —Professor Dr. Rolf Hellinger, Research and Technologies Corporate Technology, Siemens AG

Book Description
Fault current levels in land-based power systems are generally rising because of the increase in renewable generation capacity. Once the fault current level exceeds the capacity of the existing protection equipment, expensive upgrades become necessary. In order to avoid excessively expensive equipment upgrades, many fault current limitation techniques have been investigated. This thesis presents the work conducted on the design, manufacture and testing of a resistive superconducting fault current limiter (SFCL) with an integrated fast-acting vacuum interrupter. The practical application of magnesium diboride (MgB2) in round wire form was also investigated. A single-strand MgB2 SFCL coil was investigated and demonstrated repeatable and reliable current-limiting action. In practical power system applications, the development of SFCLs needs a considerable scale-up of the current-carrying capability of the MgB2 wire samples. One option is to use parallel wires in order to carry current levels in the kA range. The behaviour of a prototype three-strand MgB2 SFCL coil was assessed, which showed that each of the three wire strands shared the current approximately equally and demonstrated reliable and repeatable behaviour during testing. The MgB2 SFCL coil with multiple wire strands in parallel shows considerable potential as a practical method for scaling-up the current levels required for power system applications. One of the significant operational issues for resistive SFCLs is the temperature recovery time after a fault is cleared. A vacuum interrupter was integrated therefore into the SFCL system to quickly remove the superconducting coil from the circuit during a fault condition and allow the superconducting coil to recover whilst a bypass resistor acted as a current limiting resistor. A fast-acting actuator and its control circuit were designed and manufactured to control the operation of the vacuum interrupter. The SFCL with a prototype vacuum interrupter was successfully tested to validate the design process. The energy dissipated in the superconducting coil was significantly reduced by the fast operation of the vacuum interrupter and the recovery time significantly reduced. This research demonstrates the potential of a cost-effective and compact SFCL for the power system applications.
