New Differential Protection Method for Multiterminal HVDC Cable Networks

open access: yesEnergies, 2018
Ground faults in electrical power systems represent more than 90% of total faults. Their detection, location, and elimination are essential and must be carried out in a precise way to allow multiterminal high-voltage direct current (HVDC) cable networks ...

A Novel Ground Fault Identification Method for 2 × 5 kV Railway Power Supply Systems

open access: yesEnergies, 2015
The location of ground faults in railway electric lines in 2 × 5 kV railway power supply systems is a difficult task. In both 1 × 25 kV and transmission power systems it is common practice to use distance protection relays to clear ground faults and ...

Finite Fault Source Model for Ground Motion near Fault Zone

open access: yesIABSE Congress Reports, 2022
<p>Ground motion is categorized into near fault zone and across fault zone where impulsive component is included. The impulsive component usually causes larger damage than that by far-fault ground motion. To build a Benchmark model platform for cable-stayed bridges across-fault region for comparative analysis, the paper proposes a way combining ...

Novel Auto-Reclosing Blocking Method for Combined Overhead-Cable Lines in Power Networks

open access: yesEnergies, 2016
This paper presents a novel auto-reclosing blocking method for combined overhead-cable lines in power distribution networks that are solidly or impedance grounded, with distribution transformers in a delta connection in their high-voltage sides. The main

A New Method of Ground Fault Location in 2 × 25 kV Railway Power Supply Systems

open access: yesEnergies, 2017
Owing to the installation of autotransformers at regular intervals along the line, distance protection relays cannot be used with the aim of locating ground faults in 2 × 25 kV railway power supply systems.

Ground reaction force sensor fault detection and recovery method based on virtual force sensor for walking biped robots [PDF]

open access: yes, 2013
This paper presents a novel method for ground force sensor faults detection and faulty signal reconstruction using Virtual force Sensor (VFS) for slow walking bipeds. The design structure of the VFS consists of two steps, the total ground reaction force (

Single-Line-to-Ground Fault Location in Resonant Grounded Systems Based on Fault Distortions [PDF]

open access: yesIEEE Access, 2021
Under single-line-to-ground (SLG) faults, the voltages and currents in resonant grounded systems will inevitably be distorted. To locate the faults quickly and accurately, this paper proposes a location method based on fault distortions. The faulty phase is firstly detected according to the first SLG fault feature below, and then the faulty feeder and ...
