Influence of Negative Sequence Injection Strategies on Faulted Phase Selector Performance

open access: yesEnergies, 2022
Renewable power is expected to increase drastically in the coming years due to the energy transition. A large part of the newly installed generators will be connected to the power system through inverters and electronic converters, whose behaviour ...

Research on the Control Method of the PV Grid-Connected Inverter under an Asymmetrical Power Grid Fault

open access: yesEnergies, 2023
The negative-sequence current component and harmonic components generated when an asymmetrical fault occurs in the power grid seriously affect the normal operation of the photovoltaic (PV) grid-connected inverter.

Asymmetrical Fault Correction for the Sensitive Loads Using a Current Regulated Voltage Source Inverter

open access: yesEnergies, 2016
Numerous industrial applications involve loads that are very sensitive to electrical supply instabilities. These instances involve various types of voltage imbalances as well as more serious disturbances such as symmetrical and asymmetrical faults.

On the Use of Clarke Transformation for the Transient Analysis of Asymmetrical Faults in Three-Phase Power Systems

open access: yesEnergies
This work provides a theoretical/methodological contribution to the transient analysis of asymmetrical faults in three-phase systems. Transient analysis of three-phase systems is usually performed by resorting either to the instantaneous Symmetrical ...

Sliding Mode Control Based Supercapacitor Modeling for Dynamic Stability in DFIG Based Wind Turbines

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2022
The supercapacitor is among the elements commonly used to store energy as an important component in sustainable energy systems. In doubly fed induction generators (DFIGs), the supercapacitor is used to compensate voltage dips and damping oscillations. In

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Influence of fault asymmetric dislocation on the gravity changes

open access: yesGeodesy and Geodynamics, 2014
Abstract:A fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement along the fractures as a result of earth movement. Large faults within the Earth’s crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, energy release associated ...

Effect of Asymmetric Topography on Rupture Propagation Along Fault Stepovers

open access: yesJournal of Geophysical Research: Solid Earth, 2023
Abstract Complex fault systems are often located in regions with asymmetric topography on one side of a fault, and these systems are very common in Southern California. Along these fault systems, geometrical complexities such as stepovers can impact fault rupture.

Determination of SCC Contributed by DFIG Under Asymmetrical Short Circuit Fault

open access: yesCSEE Journal of Power and Energy Systems
For the past decades, practical calculation method of short circuit current (SCC) contributed by doubly fed induction generator (DFIG) under asymmetrical short circuit fault is deficient due to its control strategies and unlinear equipment.
