Fault ride-through enhancement of fixed speed wind turbine using bridge-type fault current limiter

Journal of Electrical Systems and Information Technology, 2016
The interaction between wind energy turbines and the grid results in two main problems, increasing the short-circuit level and reducing the Fault Ride-Through (FRT) capability during faults.

A current‐limiting DC circuit breaker with power flow control capability

IET Generation, Transmission & Distribution, 2022
Power flow controller (PFC), fault current limiter (FCL) and DC circuit breaker (DCCB) are important equipment in the DC grid. There are a large number of power electronic components in these equipment, resulting in high cost.

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).

An effective fault management scheme and comprehensive double line‐frequency ripple propagation analysis for MVDC networks

IET Generation, Transmission & Distribution, 2021
This paper proposes an effective fault management scheme for medium‐voltage direct current (MVDC) networks, which includes a virtual‐impedance‐based fault current limiter (VI‐FCL) on the DC side and a positive‐negative‐sequence (PNS) control scheme 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.

Improved Low Voltage Ride-Through Capability of DFIG with ESO Controller under Unbalanced Network Conditions

Majlesi Journal of Electrical Engineering
Under unbalanced grid condition, in a Doubly-Fed Induction Generator (DFIG), voltage, current, and flux of the stator become asymmetric. Therefore, active-reactive power and torque will be oscillating.

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.

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Plant‐protein supplementation improves thermoregulatory responses and ameliorates markers of intestinal damage during exercise in the heat

Experimental Physiology, EarlyView.
Abstract Exercise in the heat often causes gastrointestinal (GI) disturbances, which can impair performance. Single amino acid supplementation can attenuate gut damage and enhance exercise tolerance; however, the effectiveness of innate amino acid blends from plant‐based proteins remains underexplored.

Predicting the Risk of Proteinuria Based on Blood Plasma Fourier‐Transform Infrared Spectroscopy and Machine Learning Algorithms From Pregnant Women and Newborns

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Proteinuria, defined by an abnormally elevated concentration of proteins in the urine, serves as a critical biomarker for the early detection and diagnosis of preeclampsia. Elevated proteinuria levels adversely affect both maternal and foetal health, increasing the risk of preterm birth and low birth weight.
