“…Superconducting devices are known for their ability to ensure high reliability and continuous load supply. They can provide fault protection by limiting the fault current and providing an alternative source of supply in case of a short loss [26]. Different techniques for fault current limitation use a superconductor, such as resistive or magnetic fault current limiters [26].…”

To reduce emissions from the aviation industry and meet the targets set by different countries, research has been focused on investigating all-electric aircraft. To make this vision practical, superconducting machines are expected to power the propellers, as they are half the size and a third the weight of conventional machines. The main purpose of this paper is to do a higher-level study of a reliable holistic protection system for all-electric aircraft; that can reduce heat leakage and be able to detect faults reliably. Thus, three main protection systems were investigated; 1) cryogenic voltage source converter superconducting magnetic energy storage system (VSC-SMES), 2) cryogenic dc breaker integrated with superconducting fault current limiter (SFCL), and 3) machine learning algorithm for fault detection. By immersing the protection system at cryogenic temperature, the paper has shown that passive leakage can be eliminated, and thus more energy can be saved for the fuel cell. The paper has also demonstrated that using machine learning for the SFCL-dc-breaker system can consistently eliminate faults and protect the system.

“…In other words, in normal conditions, the reactor rings are aligned with minimum angular displacement, and thus the reactors' mutual inductance is relatively high. The total inductance of the device is equal to the sum of the reactors' self-inductance and their mutual inductance as given by relation (1).…”

“…The ongoing expansion of the power network and the increase of the energy production capacity can potentially reduce the effective impedance of the network and result in a higher short circuit level. The increase of the short circuit current level may lead to a series of undesired events in the network such as transient overvoltage, risk of mechanical and thermal stresses on equipment, ratio error in transformers, malfunction of protection equipment etc [1][2][3][4][5]. By the same token, the maximum short current level is an important factor in determining the size and the cost of the power equipment such as circuit breakers, bus bars, transmission lines and transformers.…”

“…However, their operation is irreversible in a sense that the fuse must be disposed and replaced for the next operation. Conversely, Fault Current Limiters (FCLs) [1][2][3][4][5] are equipment-based protection measures with variable impedance property. In addition, their operation is simply reversible without additional cost, which makes them a desirable choice.…”

The authors deal with design and analysis of an air‐core electromagnetic fault current limiter (FCL) with rotary motion. The proposed device is characterised by a simple structure, fast operating speed and reversible operation. It consists of two movable concentric air core spherical reactor rings (i.e. inner and outer rings) with variable mutual angular displacement. At normal condition, reactors are approximately aligned, and subsequently, the effective inductance/impedance of the equipment and the respective voltage drop are low. At faulty conditions, the short circuit current exerts a repulsive rotary electromagnetic torque on the reactors, which results in a fast and steady increase of the reactors angular displacement. During this process, the effective inductance of the equipment rapidly rises up to a level that effectively limits the short circuit current. To determine the effectiveness of the proposed topology in limiting the network's fault current, the inductance profile of the proposed rotary FCL and the respective fault current characteristic are compared with similar case studies (a) with linear FCL and (b) without FCL. The analysis is carried out via a finite element (FE) and supported via analytical and theoretical discussion. Finally, a down‐scale prototype of the proposed FCL was built and tested to verify the functionality of the device in the lab environment.
