Abstract

A temporary overvoltage is an oscillatory phase to ground or phase to phase over voltage that is relatively long duration and is undamped or only weakly damped.Temporary over voltages usually originate from faults, sudden charge of load, Ferranti effect, linear resonance, ferroresonance, open conductor, induced resonance from coupled circuits and so forth.The steady voltage at the open end of an uncompensated transmission line is always higher than the voltage at the sending end.This phenomenon is known as the Ferranti effect. This paper presents a study of Ferranti effect in electrical transmission line.The study is based on both software and hardware.The MATLAB program gives the locus of sending end voltage with line length which shows that receiving end voltage is greater than sending end voltage.From the experiment with transmission line simulator the values of three phase voltages at  sending end and receiving end were found which proves the Ferranti effect.These two methods were used to give the idea about the Ferranti effect.DOI:http://dx.doi.org/10.11591/ijece.v2i4.451

Abstract

This paper presents an experimental measurement of ac 50 Hz flashover voltage (kV) of hydrophobic polymer insulators. Hundred thirty five different testing conditions were used to evaluate the electrical performance of hydrophobic surfaces of composite polymer insulators. The study of flashover voltages depend on the silicone rubber (SiR) content (%) in Ethylene propylene diene monomer (EPDM) rubber, water conductivity (µS/cm), volume of water droplet (ml) and number of water droplets on the surface of polymer insulators. Artificial neural network (ANN) is used successfully to model nonlinear functions which are difficult to model using classical methods. ANN can estimate the values of flashover voltage (kV) for different polymer insulators. The proposed network is trained using different environmental wet condition such as; water conductivity, volume of water droplet and number of water droplets on the surfaces of composite different polymer. After training, the network can estimate the flashover voltage for different inputs. A comparison between the laboratory measurements of flashover voltages and computational results of ANN were convergent. The results obtained from applying ANN show that it can be used to model the data with accuracy of 96%. These results prove that ANN can be considered a successful model to evaluate the electrical performance of hydrophobic polymer insulators and predicts the best hydrophobic composite surface that withstands higher flashover voltage under wet contaminated weather condition.DOI:http://dx.doi.org/10.11591/ijece.v2i4.580

Abstract

During the last decade, Localization in wireless sensor networks (WSNs) is a broad topic that has received considerable attention from the research community. The approaches suggested to estimate location are implemented with different concepts, functionalities, scopes and technologies. This paper introduces a methodological approach to the evaluation of localization algorithms and contains a discussion of evaluation criteria and performance metrics followed by statistical/ empirical simulation models and metrics that affect the performance of the algorithms and hence their assessment. The major contribution of this paper is to analyze and identify relevant metrics to compare different approaches on the evaluation of localization schemes.DOI:http://dx.doi.org/10.11591/ijece.v2i4.247

Abstract

Miniature devices development has been greatly complementing the technology developmental trend in telecommunication. This makes the new communication technology to sail smoothly into the society and creating unexpected market for both the telecommunication providers and embedded system manufactures. However power has been the major problem in the usage of some of these devices most especially in third world countries where power is epileptically supplied. This paper proposes a prototype system which wirelessly generates DC for charging and powering power-critical handheld and remotely located devices. The design captures 900MHz radio frequency signal with a dipole antenna, which is converted into DC and stores the power in the device’s battery or use it to power it. The major aim of this paper is to provide a prototypical system which provides a cheap, constant and environmental friendly system for powering and charging power critical handheld and remote devices thereby prevents systems failure due to power loss.DOI:http://dx.doi.org/10.11591/ijece.v2i4.572

Abstract

Standalone diesel generators (DGs) are widely utilized in remote areas in Indonesia. Some areas use microhydro (MH) systems with DGs backup.  However, highly diesel fuel price makes such systems become uneconomical. This paper introduces hybrid photovoltaic (PV)/MH/ DG/battery systems with a variable charging strategy method to minimize the diesel fuel consumption. The method is applied to control the state of charge (SOC) level of the battery based on its previous level and the demand load condition to optimize the DG operation. The optimal operation shows that the hybrid PV/MH/DG/battery with the variable charging strategy needs less fuel consumption than PV/MH/DG and MH/DG systems.DOI:http://dx.doi.org/10.11591/ijece.v2i4.556

Abstract

The Problem of Automatic Generation Control of large interconnected multi-area system is necessitated by the importance of maintenance of frequency and tie-line flows at their scheduled values. Disturbance in any part of the power system network has its effect on the frequency and tie-line power flows of the entire network. Thus, It is the responsibility of the Power system engineers to ensure that adequate power is delivered to the load reliably and economically so that nominal condition will be re-established. This Research paper aims to represents how nominal value can be achieved by close loop control of real and reactive powers generated in the controllable source of the system with the help of conventional controllers.DOI:http://dx.doi.org/10.11591/ijece.v2i4.305

Abstract

One of the most important methods proposed for reduction of consumed energy in facility and ventilation systems in a building is application of ground source heat pumps (GSHPs). With regard to the enhanced use of such pumps in providing heat and cold demands in homes, commercial centers, institutions and industrial buildings analysis of their performance as well as their benefits and deficiencies compared to common ventilation systems have gained interest of many researchers. Such systems apply ground as a thermal well in summer and as a heat source in winter. They can be used in various climatic conditions in different regions. They have no combustion and they only transfer heat. In the present article first, performance conditions of ground source heat pumps (in two modes of heating and cooling) are analyzed. Then in order to assess the performance of proposed model economically, its application in Iran will be studied. Finally after introducing the proposed plan and by concluding the overall results the return time for investment will be estimated. The obtained results from graph analysis would indicate the superiority of proposed model over other plans and also it provides an appropriate general context for the researchers for a better understanding and examining this system in comparison to other systems.DOI:http://dx.doi.org/10.11591/ijece.v2i4.1463

Abstract

Vocal disorders directly arise from the physical shape of the vocal cords. Videostroboscopic imaging provides doctors with valuable information about the physical shape of the vocal cords and about the way these cords move. Segmentation of the glottal space is necessary in order to characterize morphological disorders of vocal folds. One of the main problems with the methods presented is their low level of accuracy. To solve this problem, an automatic method based on Mathematical Morphology edge detection and the Hough transformation is presented in this article to extract the glottal space from the videostroboscopic images presented. This method and two other popular algorithms, histogram and active contour, are performed on 10 sets of videostroboscopy data from excised larynx experiments to compare their performances in analyzing videostroboscopy images. The accuracy in computing glottal area of these methods are investigated. The results show that our proposed method provides the most accurate and efficient detection, and is applicable when processing low-resolution images. In this paper we used edge detection based on geometric morphology to detecting the edges of vocal cords. Then in the next step the edges that were extracted, using Hough transform change to some lines. After that through using proposed algorithm, we omit the extra lines and extract the glottis.DOI:http://dx.doi.org/10.11591/ijece.v2i4.324
