This paper represents a three-phase precision measurement system for the electronic electricity meter based on a digital signal processor (DSP) in combination with a multichannel analog-to-digital converter. The measurement system capabilities include all the usual assessments of the energy, power, voltage and current, but functionality of this precision measurement system is extended into the ...

In this paper, we present problems connected with voltage fluctuations in low-voltage networks caused by small PV sources installed an LV network. For the purpose of analysis, high-resolution data gathered at output real for 4 months 2 locations are used. Data processed to analyze impact different network parameters on and flicker. The resulting values flicker given so assessment can be made be...

One of the key aspects of power quality improvement in power system is the mitigation of voltage sags/swells and flicker. Custom power devices have been known as the best tools for voltage disturbances mitigation as well as reactive power compensation. Dynamic Voltage Restorer (DVR) which is the most efficient and effective modern custom power device can provide the most commercial solution to ...

This project proposes a voltage stability for an interline photovoltaic (I-PV) system. In an I-PV system, the inverters in a PV plant are reconfigured in such a way that two or more distribution networks / feeder are interconnected. The I-PV system is operated as a flexible ac transmission system (FACTS) device STATCOM to regulate the point of common coupling voltage on either feeder. One of th...

The paper presents a novel modulated passive power filter scheme for nonlinear load bus voltage flicker control using an error-driven, error-scaled rule based controller for online voltage stabilization.

This paper presents a detailed small-signal and transient analysis of a full bridge PWM DC-DC converter designed for high voltage, high power applications using an average model. The derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. Results obtained in the analysis of the high voltage and high power design examp...

In this paper, CMOS Sample-and-Hold (S/H) is presented. The S/H circuit is an important component in Analog-to-digital Converter (ADC). In low frequency application, the boost clock technique is used to constitute a rail-to-rail signal voltage with low distortion. The operational amplifier works as a unity gain buffer in the S/H circuit. However, a two-stage op-amp is proposed with enhanced low...

rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. among different techniques, rss-based  schemes and in particular oneof its variants which is based on graph-based semi-supervised learning (g-ssl) are widely-used approaches the superiority of this scheme is that it has low setup/training cost and at the same ti...
