<p class="IEEEAbtract"><span lang="EN-US">To make an electrical system reliable and cost-effective, its protection coordination is crucial. Protection a study to determine the trip settings of protective devices. This research proposes for Mehran University Engineering Technology, Jamshoro, Sindh. includes relays connected at each department main relay with vacuum circuit breakers (...

When a fault occurs on the transmission line, relay should send faulty signal to circuit breaker trip or isolate line. Timely detection is integral protection and management of lines in power systems. This paper focuses using threshold current voltage reduce time delay instantaneous overcurrent for 330 kV The wavelet transforms toolbox from MATLAB Simulink model were used design detect value co...

A gold(I) N-heterocyclic carbene (NHC) complex mediated hydroamination of an alkyne has been modeled using density functional theory (DFT) study. In this regard, alkyne and amine coordination pathways have been investigated for the hydroamination reaction between two representative substrates, namely, MeC≡CH and PhNH(2), catalyzed by a gold(I) NHC based (NHC)AuCl-type precatalyst, namely, [1,3-...

Abstract The present study is focussed on solving the relay coordination problem. Protection of microgrids performed through placement directional overcurrent relays (DOCR). efficacy microgrid protection depends all DOCRs placed in system. For this purpose, a number optimization techniques have been employed by power system researcher. In paper, Grey Wolf Optimizer (GWO) proposed for different ...

This paper presents a study on protection coordination of overcurrent relays (OCRs) in a distributed system by considering its different operating modes. Two different case studies which are considered in present work for protection coordination include: (i) DG interfaced distribution system in grid connected mode and (ii) DG interfaced distribution system in islanded mode of operation. The pro...

In recent years research suggests that astrocyte networks, in addition to nutrient and waste processing functions, regulate both structural and synaptic plasticity. To understand the biological mechanisms that underpin such plasticity requires the development of cell level models that capture the mutual interaction between astrocytes and neurons. This paper presents a detailed model of bidirect...

Fine binocular coordination of saccades is essential for clear binocular vision, whatever the viewing distance. When saccading between targets at far distance (for example 400 cm), the saccade starts with visual axes almost parallel (small vergence angle); coordination of saccade allows the angle to be maintained. At near distance (for example 40 cm), the eyes converge; yet the saccades should ...

Opportunistic relaying scheme is a single cooperative relay selection method based on Channel State Information. However, the failure probability of the best relay selection may become unacceptable when the number of relays increases. Although most of the existing solutions can reduce the failure probability of relay selection, they ignore the fairness of the relay selection. In order to improv...
