Cryogenic DC Circuit Breaker Based on High‐Power Press‐Pack IGBT

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This paper presents the performance of cryogenically compatible 3.3 kV/1.5 kA PP‐IGBTs as the main circuit breaker in a hybrid circuit breaker. The 3.3 kV/1.5 kA press‐pack IGBT can interrupt currents exceeding 5.1 kA when immersed in a liquid nitrogen bath. PP‐IGBTs are promising candidates for high‐power circuit breakers in cryogenically cooled power

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 ...

Optimal Protection Planning and Coordination in Microgrids With SDGs, SFCLs, and OCR Using WOA

open access: yesInternational Journal of Energy Research, Volume 2025, Issue 1, 2025.
One of the critical challenges in power system protection is ensuring proper relay coordination. To achieve optimal coordination of protection systems and ensure security, fast cleaning, and selection of types of faults is a necessary priority. This priority, when hosting synchronous distributed generations (SDGs), although technical factors like power

A Modified Loss of Synchronism Condition for Efficient Critical Clearing Time (CCT) Estimation in Transient Stability Analysis

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
Accurate determination of critical clearing time (CCT) remains a fundamental challenge in transient stability analysis of power systems, primarily due to the highly nonlinear and complex dynamic behavior of multimachine networks. Existing methods based on the loss of synchronism (LOS) condition often require intensive numerical iterations and may ...

Comparative Analysis on Current Limiting Characteristics of Hybrid Superconducting Fault Current Limiters (SFCLs) with First Half Cycle Limiting and Non-Limiting Operations

open access: yesJournal of Electrical Engineering and Technology, 2012
The application of large power transformer into a power distribution system was inevitable due to the increase of power demand and distributed generation. However, the decrease of the power transformer's impedance caused the short-circuit current of the power distribution system to be increase thus, the higher short-circuit current exceeded the cut-off
