Optimal Coordination of Distance and Two-Level Directional Overcurrent Relays for Renewable Energy-Integrated Power Networks Using Enhanced Red-Tailed Hawk Algorithm

open access: yesApplied Sciences
Optimal coordination of distance and directional overcurrent relays (DR–DOCR) aims to achieve a fast, selective, and reliable protection scheme for transmission and sub-transmission systems.

A RELAYING COORDINATION FOR DISTRIBUTION NETWORK PROTECTION

open access: yesGlobal Journal of Innovation and Emerging Technology, 2022
Fault identification is a significant task on a distribution line (DL) when a harsh disturbance occurs due to breakdown of insulation on a DL. The termination of fault diagnosis on DL should be done as soon as probable to avoid further economic and communal costs due to interruptions of load.

Optimal Coordination of Distance and Directional Overcurrent Relays Considering Different Network Topologies

open access: yesIranian Journal of Electrical and Electronic Engineering, 2015
Most studies in relay coordination have focused solely on coordination of overcurrent relays while distance relays are used as the main protection of transmission lines.

Development of an Optimal Coordination Scheme For Dual Relay Setting In Distribution Network Using Smell Agent Optimization Algorithm

open access: yesCovenant Journal of Engineering Technology, 2022
This research work is aimed at developing an optimal coordination scheme for dual relay settings in distribution system. The fault current through a relay in forward direction is usually higher than that in the reverse direction for distribution system.

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

open access: yesAdvanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Considering Pilot Protection in the Optimal Coordination of Distance and Directional Overcurrent Relays

open access: yesIranian Journal of Electrical and Electronic Engineering, 2015
The aim of the relay coordination is that protection systems detect and isolate the faulted part as fast and selective as possible. On the other hand, in order to reduce the fault clearing time, distance protection relays are usually equipped with pilot ...

Biolipid Film‐Fused Electrochemiluminescence for Multipurpose In Situ Bioassays

open access: yesAdvanced Science, EarlyView.
An ECL‐emissive, membrane‐interactive scaffold was fabricated, and facilely fused with natural and non‐native phospholipids into multifactorial mimicries of cytomembranes and vesicles for in vitro representative membrane‐process probing. Such a biointerface‐based, state‐sensitive ECL paradigm not only pinpointed proximal phenomena, including channeling

Opportunism in Multiuser Relay Channels: Scheduling, Routing and Spectrum Reuse

open access: yes, 2007
In order to understand the key merits of multiuser diversity techniques in relay-assisted cellular multihop networks, this paper analyzes the spectral efficiency of opportunistic (i.e., channel-aware) scheduling algorithms over a fading multiuser relay ...
