Transition mechanism of an Inductive-resistive Superconducting Fault Current Limiter (IR-SFCL)

open access: yesRE&PQJ
Superconducting fault current limiters (SFCL) are protective devices that limit the current in power lines when it suddenly increases above a certain safe level as a consequence of a fault. This element is connected in series with the line and has a null impedance when the line current is below the safe value (limit current) but significative increase ...

A modified synchronverter for a weak grid with virtual power circles‐based PQ decoupling scheme

open access: yesIET Renewable Power Generation, Volume 18, Issue 14, Page 2723-2736, 26 October 2024.
A VSG is essential for ensuring stability of a power systems with high penetration of renewable energies, weak grid. Its control, however, is challenging due to the coupling of the active and reactive power which thus, requires virtual impedance. This article simplifies what type, kind and magnitude of the virtual impedance required to achieve a ...

The recent development of protection coordination schemes based on inverse of AC microgrid: A review

open access: yesIET Generation, Transmission &Distribution, Volume 18, Issue 1, Page 1-23, January 2024.
The traditional OCR faced many protection performance challenges and miss‐coordination events due to the high DG penetration. Therefore, the main goal of using the voltage value that the relay discovers is to offer reliable relay coordination under high DG penetration.

A Consideration on the Extension of the Dead Time by Superconducting Fault Current Limiter [PDF]

open access: yes, 2002
This paper presents the results of analyses of the extension of the dead time by superconducting fault current limiter (SFCL). Although SFCL is generally used for the purpose of limiting of fault currents, it can also be used to stabilize synchronous ...

A Novel Transient Analysis of Multiterminal VSC‐HVDC System Incorporating Superconducting Fault Current Limiter

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
Power transmission using a voltage source converter‐ (VSC‐) based high‐voltage direct current (HVDC) system offers autonomous control of real and reactive power, constant DC voltage polarity, and bidirectional power flow. This helps to realize the multiterminal VSC‐HVDC system and its integration into renewable energy sources to meet the growing power ...
