A Scheme of DC-side Short-circuit Protection for Bi-directional Converterin Urban Rail Traction Power Supply System

Kongzhi Yu Xinxi Jishu, 2021
Using bi-directional converters for traction power supply in urban rail transit, traditional PWM rectifiers cannot meet the requirement of DC feeder protection for 27 kA short-circuit current with 120 ms continuous time.

Field Test and Short-circuit Test of HTS Power Cable

Journal of Physics: Conference Series, 2006
In order to cope with the increase in the electric power demand and an alternative technology to the conventional electric power transmission cables, it's hoped that high temperature superconducting (HTS) cable is developed. In case the HTS cable is introduced into the actual power grid, its length can extend up to several kilometers.

Short-circuit model of the DFIG considering coordinated control strategy of grid- and rotor-side converters

Energy Reports, 2022
The short-circuit current calculation is of vital importance for the power system. With a high proportion of new energy sources, the setting of relay protection and the selection of electrical equipment have been severely degraded.

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...
