A modified flux-coupling type superconducting fault current limiter (SFCL) is proposed here for suppressing currents. The SFCL consists of a coupling transformer, an yttrium barium copper oxide (YBCO) pancake coil, and controlled switch. By flexibly adjusting the switch's contact states based on system operational conditions, transformer's primary inductance as well YBCO coil's normal-state res...

To reduce emissions from the aviation industry and meet targets set by different countries, research has been focused on investigating all-electric aircraft. make this vision practical, superconducting machines are expected to power propellers, as they half size a third weight of conventional machines. The main purpose paper is do higher-level study reliable holistic protection system for aircr...

The protection of high voltage direct current (HVDC) grids is a challenge considering that the system must detect, locate, and interrupt large fault currents in few milliseconds. Resistive type superconducting limiters (R-SFCL) can help solve difficult task, reducing extremely demanding ratings HVDC circuit breakers. This paper presents different approaches to model R-SFCLs order analyze their ...

an approach for assignment of the optimal location and tap changer adjustment related to flux-lock type superconducting fault current limiters with tap changer (tc-flsfcl) is used in this paper by debating the reduction of fault current flowing from each device and enhancement of reliability varying with customer type in a distribution network connected with distribution generation (dg). tc-fls...

For the extraction of wind energy through a doubly-fed induction generator (DFIG), low voltage ride (LVRT) is an essential technical requirement specified by transmission system operator (TSO). Under grid fault condition, DFIG should remain in connection with for certain minimum period and offer reactive power support as required TSO. A cooperative control scheme consisting hardware solution su...

This paper proposes an exhaustive study about the performance analysis of Doubly Fed Induction (DFIG) under abnormal condition. Now a day, majority of power network countenance the problem of over current and grid connectivity issues. SFCL (Superconducting Fault Current Limiter), which have the competence to limit the fault current and protect the equipments from damage. SMES (Superconducting M...

With the development of a distributed generation, direct current (DC) load and energy-storage equipment, voltage-source-converter-based medium-voltage DC systems (VSC-MVDC) have attracted more attention due to its low power consumption, high reliability, independent control so on. However, VSC-MVDC has problem fault isolation, which requires fast-acting circuit-breakers isolate faulty lines ens...

This paper presents the design of a Superconducting Fault Current Limiter (SFCL) and calculation results forces stresses in windings resistive fault current limiter. The limiter consists two parallelly connected magnetically coupled windings, cooled by single stage cryocooler. Magnetically compensated made HTS tape give very low voltage on at nominal current. Limitation short-circuit time value...
