Application of thyristor controlled phase shifting transformer excitation impedance switching control to suppress short-circuit fault current level

open access: yesJournal of Modern Power Systems and Clean Energy, 2018
Short-circuit fault current suppression is a very important issue in modern large-interconnected power networks. Conventional short-circuit current limiters, such as superconducting fault current limiters, have to increase additional equipment ...

Application of resistive super conductor fault current limiter for protection of grid-connected DGs

open access: yesAlexandria Engineering Journal, 2018
Penetration of Distributed Generation (DG) into the power system causes technical problems and bad effects on the safety of the system due to increasing the short circuit levels in transmission and distribution networks. So, there will be miscoordination

Design of Self-Powered Solid-State Fault Current Limiters for VSC DC Grids

open access: yesFrontiers in Energy Research, 2021
-Fault current limiters (FCLs) can suppress the rise of short-circuit fault currents in voltage source converter (VSC) based DC grids. However, the power electronic switches of FCLs need extra source equipment to supply the required power, which ...

Superconducting fault current limiter application in a power-dense marine electrical system [PDF]

open access: yes, 2011
Power-dense, low-voltage marine electrical systems have the potential for extremely high fault currents. Superconducting fault current limiters (SFCLs) have been of interest for many years and offer an effective method for reducing fault currents.

Inductive Fault Current Limiters in VSC-HVDC Systems: A Review

open access: yesIEEE Access, 2020
Fast emerging fault current levels in high voltage direct current (HVDC) systems has always been a significant obstacle to building a safer and more reliable grid. Inductive fault current limiters (FCLs), compared with its resistive counterpart, are very

Protective coordination of main and backup overcurrent relays with different operating modes of active super-conducting current controller [PDF]

open access: yesMaejo International Journal of Science and Technology, 2014
Active superconducting current controllers (ASCCs) are new generation of series compensators, which can also be categorised as fault current limiters because of their ability to decrease the fault current continuously.

Optimal Protection Coordination of Active Distribution Networks With Synchronverters

open access: yesIEEE Access, 2022
Synchronverters are inverters imitating synchronous generators (SGs) to curb adverse impacts of traditional inverters on power networks. However, synchronverters may generate unlimited currents during faults.
