Effects of the fault inception angle in fault-induced transients

open access: yesIET Generation, Transmission & Distribution, 2012
The analysis of fault-induced transients in three-phase overhead transmission lines can provide extensive information about the fault type, detection, location, direction and sustained time in satisfactory agreement with real application in protective relays.

Effective numerical simulation of fault transient system

open access: yesInternational Journal of Modeling, Simulation, and Scientific Computing
Power systems, including synchronous generator systems, are typical systems that strive for stable operation. In this paper, we numerically study the fault transient process of a synchronous generator system based on the first benchmark model. That is, we make it clear whether an originally stable generator system can restore its stability after a ...

A New Fast Peak Current Controller for Transient Voltage Faults for Power Converters

open access: yesEnergies, 2015
Power converters are the basic unit for the transient voltage fault ride through capability for most renewable distributed generators (DGs). When a transient fault happens, the grid voltage will drop suddenly and probably will also suffer a phase-jump ...

Line Selection Device of Small Current Single-phase Grounding Fault Based on Integrative Line Selection Strategy

open access: yesGong-kuang zidonghua, 2012
For the deficiency of single line selection principle, the paper proposed integrative line selection strategy, namely zero sequence admittance method, zero sequence susceptance increment method and zero sequence conductance method based on steady-state ...

Simulation research on zero-module characteristics of single-phase grounding fault in mine power supply system

open access: yesGong-kuang zidonghua, 2018
For poor actual protection effect of existing line selection methods based on characteristic quantity of single-phase grounding fault, a simulation model of mine power supply system was established in RTDS/RSCAD real-time digital simulation system taking

An Adaptive Reclosing Scheme for Cross-Line Faults on Double-Circuit Wind Power Outgoing Lines with Shunt Reactors

open access: yesEnergies
Wind turbines are vulnerable to negative sequence current injection, the conventional automatic reclosing scheme for wind power outgoing lines, since we may inject negative sequence components into the system and reclose it without distinguishing the ...

A Reliability Scheduling Algorithm for the Static Segment of FlexRay on Vehicle Networks

open access: yesSensors, 2018
FlexRay is a next-generation in-vehicle communication protocol which works in real time with flexibility. The most common applications in FlexRay are high bandwidth. X-by-wire applications, such as brake by wire and throttle by wire. However, there is no

Concave Sparsity-Assisted Generalized Dispersive Mode Decomposition for Drive Motor Bearing Fault Diagnosis of Vehicles

open access: yesWorld Electric Vehicle Journal
As a critical element of the drive motor, rolling bearings are susceptible to localized defects under complex loads and varying operating conditions. Such defects typically generate periodic transient shocks, which reflect bearing fault features. However,

Transient Protection of UHV Busbars Based on Standardized VMD-Shannon Entropy

open access: yesIEEE Access
Transient bus protection exhibits ultra-high-speed action, yet displays low reliability under weak fault conditions. This paper proposes a novel multidimensional fault analysis framework to address this issue.

A tool for detecting transient faults in execution of parallel scientific applications on multicore clusters

open access: yesJournal of Computer Science and Technology, 2014
Transient faults are becoming a critical concern among current trends of design of general-purpose multiprocessors. Because of their capability to corrupt programs outputs, their impact gains importance when considering long duration, parallel scientific
