Transient Stability Improvement using Resistive-type Superconducting Fault Current Limiters (R-SFCL)

International Journal of Engineering Technology and Sciences, 2019
The rapid growth in the demand for electrical energy due to the astronomic growth in population has led to increase in the system fault current levels. This increase in fault current if not properly checked, could lead to system collapse. Superconducting Fault Current Limiters (SFCLs) are used in power system networks to mitigate against high fault ...

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

Journal 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

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

International 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

International 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 ...

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

RE&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 ...
