Pengaruh Sistem Pengetanahan Terhadap Arus Gangguan Tanah Pada Sistem Distribusi 20 Kv Di PLN Palur Dengan Menggunakan Etap 12.6 [PDF]

open access: yes, 2016
PT. PLN Rayon Palur is the electric company which is engaged in distribution of electrical energy and maintenance of the electrical grid to consumers. In the process of distribution of electrical energy, a fault is often recurred, one of them is a ground

Short circuit study of fixed speed wind turbines with STATCOM in distribution networks [PDF]

open access: yes, 2015
The increased penetration of wind farm in distribution networks has brought changes in the performance of the whole system. Such disadvantages when connecting one of these distributed generation sources is reduced voltage and power stability of the AC ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Pilot Protection of a Distribution Network with Distributed Generators Based on 5G and Dynamic Time Warping Considering Cosine Transform

open access: yesEnergies, 2023
The application of 5G-based communication for pilot protection in a distribution network with distributed generators is becoming increasingly widespread, but the existence of a 5G communication transmission data delay adversely affects the rapidity and ...

Turn-to-turn fault protection technique for synchronous machines without additional voltage transformers [PDF]

open access: yes, 2017
This paper presents a novel protection technique for the detection of inter-turn faults in synchronous machines. It is based on the calculation of voltage in the stator windings from the usual phases and neutral voltage, typically available in ...

Research of Single-phase Grounding Fault Simulation for Small Current Grounding System

open access: yesDEStech Transactions on Environment, Energy and Earth Sciences, 2017
Our country generally uses small current grounding system (the neutral point no direct grounding system). Due to the fault current is too small to identify. So the distribution network operators have been plagued by this kind of fault line selection accuracy. This research establishes simulink model to analyze the fault of single-phase grounding system

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

An adaptive reclosing strategy for UHV AC transmission lines based on phase difference of single-end induced voltage

open access: yesInternational Journal of Electrical Power & Energy Systems
In ultra-high voltage (UHV) AC transmission systems, single-phase to ground faults account for more than 80 % of all faults. If reclosing is performed blindly under permanent fault conditions after a single-phase to ground fault, the system may suffer ...
