Identification of the flicker source in the power supply systems

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2022
THE PURPOSE. To consider issues related to the study of methods for determining the sources of violations of the quality of electrical energy in power supply systems, in particular consumers which create rapid voltage changes or voltage fluctuations that

Improved Method for Determining Voltage Unbalance Factor Using Induction Motors

open access: yesEnergies, 2022
This work shows an alternative method to determine the Voltage Unbalance Factor in a power grid by using both the mean value of the line voltages and Current Unbalance Factor in induction motors. Twenty unbalanced voltage points on three induction motors

Timing analysis considering temporal supply voltage fluctuation

open access: yesProceedings of the 2005 conference on Asia South Pacific design automation - ASP-DAC '05, 2005
This paper proposes an approach to cope with temporal power/ground voltage fluctuation for static timing analysis. The proposed approach replaces temporal noise with an equivalent power/ground voltage. This replacement reduces complexity that comes from the variety in noise waveform shape, and improves compatibility of power/ground noise aware timing ...

Superconducting Quantum Interference in Fractal Percolation Films. Problem of 1/f Noise

open access: yes, 1998
An oscillatory magnetic field dependence of the DC voltage is observed when a low-frequency current flows through superconducting Sn-Ge thin-film composites near the percolation threshold.

Hierarchical approach to 'atomistic' 3-D MOSFET simulation [PDF]

open access: yes, 1999
We present a hierarchical approach to the 'atomistic' simulation of aggressively scaled sub-0.1-μm MOSFETs. These devices are so small that their characteristics depend on the precise location of dopant atoms within them, not just on their average ...

Length-Independent Voltage Fluctuations in Small Devices

open access: yesPhysical Review Letters, 1987
Les fluctuations de tension dans les lignes monodimensionnelles de longueur L inferieure a la longueur de coherence de phase ne sont pas universelles mais divergent comme L −2 . On montre, en utilisant les relations de Onsager et l'additivite des tensions, que les fluctuations de tension sont independantes de la distance entre les indicateurs de ...

Quantum phase slips and voltage fluctuations in superconducting nanowires [PDF]

open access: yes, 2017
We argue that quantum phase slips (QPS) may generate non‐equilibrium voltage fluctuations in superconducting nanowires. In the low frequency limit we evaluate all cumulants of the voltage operator which obey Poisson statistics and show a power law ...

High-precision bus voltage control based on NLESO and TSMC predicted load current and grid voltage differential feedforward

open access: yesFrontiers in Energy Research, 2023
Power battery test equipment is widely used to produce and test new energy vehicles and storage containers. To address the problem of DC bus voltage fluctuations that affect the accuracy of output voltage and current, a high-accuracy bus voltage control ...

An adaptive power control method for soft open points based on virtual impedance

open access: yesFrontiers in Energy Research
The fluctuations in power output from distributed power sources are rapid and dramatic, causing voltage fluctuations in the distribution network that threaten the safety of electricity consumption.

Probe-configuration dependent dephasing in a mesoscopic interferometer

open access: yes, 2003
Dephasing in a ballistic four-terminal Aharonov-Bohm geometry due to charge and voltage fluctuations is investigated. Treating two terminals as voltage probes, we find a strong dependence of the dephasing rate on the probe configuration in agreement with
