Research on Method and Device for Measuring Unbalanced Current of High Voltage Capacitor Bank in Converter Station

Zhongguo dianli, 2019
Complex electromagnetic field in converter station poses a serious interference to the field test of unbalanced current of high voltage capacitor bank, and the unbalanced current is too small to be accurately measured directly during the test. This paper

A comparative study of methods for estimating virtual flux at the point of common coupling in grid connected voltage source converters with LCL filter [PDF]

, 2016
Grid connected Voltage Source Converters (VSCs) with LCL filters usually have voltage measurements at the filter capacitors, while it can be important to control the active or reactive power injection at the grid-side of the LCL filter, for instance at a

The cooperative regulation of miR‐221 by APE1 and AUF1 impacts p27Kip1 defining a miR signature relevant for cervical cancer

FEBS Open Bio, EarlyView.
A regulatory axis involving APE1, AUF1, and miR‐221 is proposed. Pri‐miR‐221 is processed by DROSHA and DICER to generate mature miR‐221, which targets p27Kip1 mRNA. APE1 and AUF1 compete for pre‐miR‐221 binding. Reduced APE1/AUF1 levels impair miR‐221 biogenesis, decrease p27Kip1 mRNA degradation, and promote cell cycle progression, chemoresistance ...

Improving the Performance of Low Voltage Networks by an Optimized Unbalance Operation of Three-Phase Distributed Generators [PDF]

, 2019
This work focuses on using the full potential of PV inverters in order to improve the efficiency of low voltage networks. More specifically, the independent per-phase control capability of PV three-phase four-wire inverters, which are able to inject ...

Erythropoietin modulates hepatic inflammation, glucose homeostasis, and soluble epoxide hydrolase and epoxides in high‐fat diet‐induced obese mice

FEBS Open Bio, EarlyView.
Erythropoietin administration suppresses hepatic soluble epoxide hydrolase (sEH) expression, leading to increased CYP‐derived epoxides. This is associated with a shift in hepatic macrophage polarization characterized by reduced M1 markers and increased M2 markers, along with reduced hepatic inflammation, suppressed hepatic lipogenesis, and attenuated ...

Power quality enhancement of unbalanced Distributed-Resources based on triple-loop compensation

Ain Shams Engineering Journal
Distributed generation (DG) allows the microgrid (MG) to be more active and flexible. However, MG is exposed to some power quality (PQ) issues such as harmonics and voltage sag/swell especially during unbalanced loading.

Direct power control of voltage source inverters with unbalanced grid voltages

IET Power Electronics, 2008
A new approach of direct power control (DPC) of a voltage source inverter for achieving symmetrical grid currents under unbalanced grid voltage conditions is presented. In these situations, negative sequence components appear on the grid voltage vector, leading to distorted currents if the power is maintained constant. Nevertheless, sinusoidal balanced

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

A COMPUTER CALCULATION FOR TENTATIVE ELECTRICAL SYSTEM IMPROVEMENT BY REACTIVE POWER COMPENSATION CONSIDERING SYSTEM UNBALANCED [PDF]

, 2013
An improvement of unbalanced distribution system operation is carried out by reactive power compensation. The lagging reactive power demand is compensated by allocating a number of three-phase shunt capacitors.
