Tomonaga-Luttinger physics in electronic quantum circuits [PDF]

, 2013
In one-dimensional conductors, interactions result in correlated electronic systems. At low energy, a hallmark signature of the so-called Tomonaga-Luttinger liquids (TLL) is the universal conductance curve predicted in presence of an impurity.

Time-domain fault location method for wind farm double-circuit lines based on circumfluence component

International Journal of Electrical Power & Energy Systems
The short-circuit current output by new energy power supplies during faults exhibits characteristics such as frequency shifting, a high harmonic content ratio, limited amplitude, and unequal positive and negative sequence impedances. This presents a risk

Microwave Slow-Wave Structure and Phase-Compensation Technique for Microwave Power Divider [PDF]

, 2014
In this paper, T-shaped electromagnetic bandgap is loaded on a coupled transmission line itself and its electric performance is studied. Results show that microwave slow-wave effect can be enhanced and therefore, size reduction of a transmission-line ...

The determination of short circuits and grounding faults in electric power systems using time-frequency analysis

Journal of Energy in Southern Africa, 2017
In order to ensure that electrical energy reaches consumers uninterrupted, researchers constantly try to improve power transmission lines. To realize this improvement, probable faults should be analysed through every known method, and new methods should ...

Analysis of a Balanced Short Circuit on a Sulbagsel Electrical System by Using The FFA-ABC Method Approach

Journal of Applied Engineering and Technological Science, 2023
Fault studies are an important part of electrical power system analysis. The purpose of this study was to determine the amount of line current at the point of disturbance when a three-phase balanced fault occurs in the real Sulbagsel electrical system ...

Multiscale Modeling and Simulation of Organic Solar Cells [PDF]

, 2012
In this article, we continue our mathematical study of organic solar cells (OSCs) and propose a two-scale (micro- and macro-scale) model of heterojunction OSCs with interface geometries characterized by an arbitrarily complex morphology.

Fault tidentification method of outage transmission line based on convolutional neural network and wavelet packet decomposition

Diance yu yibiao
When the transmission line is in a hot standby state, a short circuit fault may still occur on the shutdown circuit. Accurate judgment of the fault state of the shutdown line can effectively avoid impact on power system and facilitate the failure ...
