Expanded polystyrene (EPS) geofoam seismic buffers can be used to reduce earthquake-induced loads acting on rigid retaining wall structures. A numerical study was carried out to investigate the influence of wall height; EPS geofoam type,... more
Light emitting diodes (LEDs) are current driven devices. So, it is essential to maintain the stability of LED voltage and current. Variation of temperature may cause of instabilities and bifurcations in the LED driver. Driving LEDs from... more
This document proposes a photovoltaic (PV) based single-phase dynamic voltage restoration (DVR) device, it eliminates both sag and swell voltage and compensates for power. The proposed system requires a power source to compensate for the... more
At the point of common coupling (PCC), the summation of two harmonic voltage vectors at same frequency is only certain if their amplitudes and phase angles are well known. Therefore, there are many cases where the phase angle difference... more
Three-level NPC active-front-end three-phase (3LAFE) converters can be applied to high-power medium voltage applications, with 4-quadrant unity-power-factor operation, allowing a broad range for power conversion systems, such as... more
Improving power quality play a vital role in distribution systems since, these are majorly connected to nonlinear loads. Nonlinear loads generate harmonics which in turn disturb the source of supply. The damped double tuned filters can be... more
Harmonic pattern scanner expert advisor for the trading platform MT5. Scans markets on different time frames and for multiple patterns. Scanning is performed on multiple standard and custom time frames. Radar scanner shows overall scan... more
Il volume propone un'esposizione storica sul pensiero musicale teorico dalla tarda antichita alla fine del medioevo, affrontando tematiche di teoria musicale, filosofia e scienza.
Currently available harmonic pattern indicators on the web, 2015
Power electronics play a significant role in different areas of technology, more usage of power electronic devices lead to more harmonic content and various power quality issues in the system. Therefore, power quality gains more... more
Abstract-Improved reliability and fault tolerant operation of inverter-fed variable frequency ac drives are very impor-tant for critical industrial applications. The paper describes variable frequency, variable voltage operation of a... more
ABSTRAK Krisis energi listrik yang melanda indonesia menyebabkan beberapa persoalan dalam bidang ketenagalistrikan, sehingga dilakukan upaya untuk mengatasi krisis energi listrik, dengan melakukan peningkatan efisiensi dari peralatan yang... more
The harmonic mitigation using shunt active filters are most widely used in industrial and commercial applications. In this paper a Multi-Level Inverter is considered as DSTATCOM to compensate harmonics. The mathematical modeling of the... more
The problem of quality electrical energy provided to the users has arisen. This is due to the increasing presence in network of nonlinear loads.They constitute a harmonic pollution source of the network, which generate many disturbances,... more
— Harmonics are found to have deleterious effects on power system equipments including transformers, capacitor banks, rotating machines, switchgears and protective relays. Transformers, motors and switchgears may experience increased... more
Nowadays solar power is one of the most suitable energy source for power generation. In practice, due to routine starting of solar power plant at every day, as a result of switching effects inrush current produces in grid connected... more
Bringing together evidence preserved by Aristoxenus, Aristides Quintilianus, Ptolemy, Porphyry and the Greek musical handbooks in a unified framework, this article and its sequels show how the Classical modulation system reconstructed in... more
One of the major electrical load on a utility grid is industrial, street and residential lightings. To enhance the energy efficiency and as a measure of energy conservation, incandescent lamps (IL) are replaced with the modern lights.... more
