Power Quality (PQ) parameters such as voltage RMS value, Total Harmonic Distortion (THD), and Power Factor (PF) are main topics to be considered in the connection of sensitive loads to the grid. In this paper, a Unified Power Quality Conditioner (UPQC) based on an Indirect Matrix Converter (IMC) is proposed to address some PQ issues as mitigation of voltage harmonics and compensation of sags an...

In this paper, we examine what kinds of social choice correspondences (SCCs) are implementable in Nash equilibria by “natural” mechanisms in divisible pure public goods economies. Then, we found conditions for SCCs to be Nash implementable by each of these four natural mechanisms. These characterizations of SCCs depend on the number of goods. First, regardless of the number of goods, the class ...

-Power quality (PQ) monitoring is an important issue to electric utilities and many industrial power customers. This paper presents a DSP-based hardware monitoring system based on a recently proposed PQ classification algorithm. The algorithm is implemented with a Texas Instruments (TI) TMS320VC5416 digital signal processor (DSP) with the TI THS1206 12-bit 6 MSPS analog to digital converter. A ...

Background: Paraquat (PQ), an herbicide, is a very poisonous compound for both humans and animals. This study was conducted to examine the protective effect of the Coenzyme Q10 (CoQ10) in newborn rats from pregnant rats pre-treated with PQ. Methods: The experiments were conducted on 25 rats, divided in five groups randomly and equally: 1 - Control Group received normal saline (0.1ml/day); 2...

Photovoltaic (PV) generation systems have been increasingly used to generate electricity from renewable sources, attracting a growing interest. Recently, grid connected PV micro-generation facilities in individual homes have increased due to governmental policies as well as greater attention by industry. As low voltage (LV) distribution systems were built to make energy flow in one direction, t...

edaravone, an antioxidant and radical scavenger, showed protective effects against oxidative stress-like condition. paraquat (pq) is a toxic herbicide considerable evidence suggests that oxidative stress and mitochondrial dysfunction contribute to pq toxicity. in this study, protective effect of edaravone against pq induced toxicity and reactive oxygen species (ros) generation in a549 cells and...

Power quality (PQ) monitoring is important for both the utilities and also users of electric power. The most widespread measurement instrument used PQ PQM (Power Quality Monitor) or PQA Analyzer). In this paper we propose usage PMU data parameters monitoring. We present a new methodology classification based on data. proposed tested with real measurements performed in distribution system using ...

Abstract: This paper presents a dual neural network based technique for detecting and classifying the power quality disturbances. In the proposed method, Adaptive Linear Neural Network is used to extract the rms voltage for harmonics and Interharmonics estimations. With the help of these indices, PQ disturbances such as Sag, Swell, Outages are detected and classified, Harmonics and Interharmoni...

In this paper, a novel method for the classification of power quality events is illustrated. Fifteen types consisting single and multi-stage disturbances are considered study. A database synthetic PQ generated in MATLAB using mathematical models. The signals passed through modified Stockwell transform second-order Gaussian window that provides ST matrix. From matrix, various statistical feature...
