Current-limiting characteristics of saturated iron-core fault current limiters in VSC-HVDC systems based on electromagnetic energy conversion mechanism

Journal of Modern Power Systems and Clean Energy, 2018
A common method to examine the current-limiting performance of saturated iron-core fault current limiter (SI-FCL) in high-voltage direct-current transmission based on voltage source converter (VSC-HVDC) systems is to solve differential equations based on

A voltage-clamped bidirectional fault current limiter based on a three-winding coupled inductor for DC power grids

International Journal of Electrical Power & Energy Systems
The DC fault is a serious challenge to voltage-source-converter-based HVDC (VSC-HVDC) systems, and the fault current limiter (FCL) is one of the key measures to solve the DC fault and reduce the capacity of the DC circuit breaker.

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).

An adaptive virtual impedance fault current limiter for optimal protection coordination of islanded microgrids

IET Renewable Power Generation, 2022
Fault currents of inverter‐interfaced distributed generators (IIDGs) depend on inverter controllers. Thus, IIDGs fault currents are different than those of synchronous‐based DGs, both from the magnitude and waveshape perspectives.

Protection System for LVDC Distribution Networks Using a Fault Current-Limiting Converter and Protection Zones

IEEE Access, 2023
In this study, we propose a generalized protection system for low-voltage DC (LVDC) distribution networks based on fault current-limiting (FCL) and the concept of protection zones (PZs).

DC Current Limiting Characteristics of Flux-Coupled Type SFCL Using Superconducting Element Connected in Parallel in a DC System

Energies, 2021
In this paper, the fault current limiting (FCL) characteristics of a flux-coupled type superconducting fault current limiter (SFCL) with parallel connection between two windings in a DC system were analyzed. The flux-coupled type SFCL was composed of two

Large Language Models Aligned With Medical Experts on Established Topics but Were Less Aligned on Emerging or Debated Topics in Posterolateral Corner Treatment: An Artificial Intelligence‐Augmented Delphi Study

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate how Large Language Models (LLMs) align with a concurrently performed human medical expert‐modified Delphi study on the posterolateral corner and to qualitatively analyze LLM behavior. Methods Four commercially available and current LLMs (Gemini‐2.5‐Pro. GPT‐4o, o4‐mini, and o3) were tasked with rating posterolateral corner consensus

Model‐Informed Dose Optimization of Anakinra in Preterm Neonates Implications for Safe and Effective Dosing

Clinical Pharmacology &Therapeutics, EarlyView.
Anakinra, an interleukin‐1 receptor antagonist, shows promise for reducing inflammatory complications of premature birth. However, the pharmacokinetics (PK) of anakinra in neonates has not been characterized, limiting evidence‐based dosing. This study aimed to develop a population PK model for anakinra to guide dosing in preterm neonates.
