Research ArticleOpen accessIn the abstractFeedback of the Input Voltage in FDTC Control Using a Three-Level NPC-VSIR. Zaimeddine, E.M. BerkoukA new control structure for sensorless induction machine dedicated to electrical drives using a three-level voltage source inverter VSI-NPC is completely analysed. The amplitude and the rotating velocity of the flux vector could be controlled freely. Both fast torque and optimal switching logic could be achieved; the selection is based on the value of the stator flux and the torque. … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,690 accessesView PDFCite

HemalathaGrid Computing is a promising infrastructure and technology that involves the integrated and collaborative use of Computers, networks, databases and scientific instruments owned and managed by multiple organizations. In this context our research primarily aims at developing an application framework for monitoring the Performance of Power Transmission and Distribution System using Grid Computing. Power Transmission and Distribution System of Electrical … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 6,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractFast Power Loss Computation and Shunt Capacitor Insertion Using Fuzzy Logic TechniqueWagah F. Mohammad, Nabil Tawalbeh, Kasim M. Al-AubidyFast power loss computation was implemented using supervisory control and data acquisition system (SCADA) with personal computer. Logic Control Array (LCA) and EPROM circuits were used to implement SCADA system to facilitate the required measurements to obtain the daily load profile for residential and commercial customers. LCA, EPROM and PC were used to simplify the electronic circuits, reduce the cost … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,395 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer Aided Transient Stability AnalysisNihad M. Al-Rawi, Afaneen Anwar, Ahmed M. Abdul-MajeedA program for handling and improving the transient stability of the Iraqi Super Grid electrical network was developed. The idea was demonstrated by applying it to the outages of the main generating units. The methodology was built upon a state of increasing power transfer through the healthy portion of network during disturbances. There were three parts concerned; the first part … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,946 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimplification of Sun Tracking Mode to Gain High Concentration Solar EnergyOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanPower conversion from solar thermal energy to electrical energy is still very cost-intensive. Serious effort has to be given in the development of the concentrator or heliostat structure expenditure which contributing the most expensive component in a central receiver solar power plant. With current development to find alternatives and lower down the capital, a new mode of sun tracking has … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiagnosis of MV Oil Filled Cable Terminations with X-Ray Imaging and Infrared (IR) ThermographyMohd. Rafi Adzman, Ismail Daut, Muzamir Isa et al.A main purpose of doing a diagnostic in cable system including its accessories such as impregnated paper insulated oil filled cable termination is to predict failure before they occur. Those cable and accessories, which are about to fail, can be replaced, thereby reducing the incidence of electrical system failure, thus reducing the electricity outages. This paper presents the work carried … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Logic Controller Based Three-phase Shunt Active Filter for Line Harmonics ReductionC. Sharmeela, M. R. Mohan, G. Uma, J. BaskaranHarmonic distortion is a form of electrical noise. It is a superposition of signals, which are of multiples of fundamental frequency. Proliferation of large power electronic systems results in increased harmonic distortion. Harmonic distortion results in reduction of power quality and system stability. This paper presents fuzzy control applicable for active power filter for three-phase systems, which are comprised of … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Based Energy Management of a Domestic Photovoltaic PanelMaher Chaabene, Mohsen Ben Ammar, Ahmed ElhajjajiThis study introduces a new switching mean giving a real time optimum connection mode of domestic apparatus on either the electrical grid or a photovoltaic panel (PVP) output. A fuzzy algorithm makes the decision which ensures the optimal energy management basing on the PVP generation and apparatus states with respect to energy save criteria. Validation was driven on a 1kW … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,009 accessesView PDFCite
