Control Strategies for a Power Electronic Based Fault Current Limiter (FCL) in No-Fault Operation

RE&PQJ
Fault current limiters (FCL) in electrical power systems offer the opportunity to reduce short-circuit stresses to the system in the case of faults. But as electrical power systems are normally operated without faults most of the time, FCLs must not have negative effects during these periods of normal operation.

Analysis of the fault current limiting requirement and design of the bridge‐type FCL in the multi‐terminal DC grid

IET Power Electronics, 2018
In the multi‐terminal flexible dc grid, it is important for the healthy network to ride through the dc fault. The converters should operate continuously after dc faults, staying unblocked. But the existing selective protection and isolation method may fail to react swiftly enough, because the propagation speed of the dc fault current is extremely fast.

Disaster Relief Through a Complex Adaptive System Perspective: Firms' Motivations, Activities, and the Role of Operations Adaptability in Overlapping Landscapes

Journal of Business Logistics, Volume 47, Issue 4, October 2026.
ABSTRACT Natural disasters disrupt the normal functioning of both communities and businesses. However, past literature often segregates the disaster relief view from the business continuity perspective, leaving a gap in understanding how firms can proactively support relief efforts.

Analytical Modeling of Rotary Electromagnetic Fault Current Limiter

IEEE Access, 2023
Rotary electromagnetic fault current limiter (FCL) is an emerging technology for limiting fault currents in the power network. The device consists of two movable air-core spherical reactor rings (i.e., inner and outer rings).

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Placement optimization of Multi-Type fault current limiters based on genetic algorithm

Global Energy Interconnection, 2021
The fault current limiter (FCL) is an effective measure for improving system stability and suppressing short-circuit fault current. Because of space and economic costs, the optimum placement of FCLs is vital in industrial applications. In this study, two

Control Design for a Power Electronic Based Fault Current Limiter (FCL)

RE&PQJ
This paper shows a solution for controlling shortcircuit currents of a power electronic based Fault Current Limiter (FCL). A model for control design of three-phase short-circuit currents will be presented. A way of limiting the maximum aperiodic short-circuit current is derived with special regards to the stability of the entire system.
