Research ArticleOpen accessPhrase in the titleA NOVEL ARTIFICIAL HYDROCARBON NETWORKS BASED SPACE VECTOR PULSE WIDTH MODULATION CONTROLLER FOR INDUCTION MOTORSHiram Ponce, Luis Ibarra, Pedro Ponce, Arturo MolinaMost of machine-operated industrial processes implement electric machinery as their work sources, implying the necessary improvement of control techniques and power electronics drivers. Many years have passed since the control conflicts related to induction motors have been overcome through torque-flux control techniques so their advantages over direct current motors have made them to be the most common electric actuator found … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 26 Feb 2014 · 7,039 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Dynamic Voltage Restorer for Voltage Sag Mitigation in a Refinery with Induction Motors LoadsTarek I. El-Shennawy, Abdel-Mon’em Moussa, Mahmoud A. El-Gammal, Amr Y. Abou-GhazalaProblem statement: ANRPC is a refinery based in Alexandria, Egypt. The plant was subjected to several shutdowns due to tripping of large induction motors, either by under voltage or by over current relays, sometimes by the mechanical protection. The main cause for such unplanned shutdowns was voltage sags. The Dynamic Voltage Restorer (DVR) has recently been introduced to protect the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,922 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleVoltage Sag Effects on the Process Continuity of a Refinery with Induction Motors LoadsTarek I. ElShennawy, Mahmoud A. El-Gammal, Amr Y. Abou-GhazalaProblem statement: Process continuity of industrial plants (like a refinery) is subjected to several shutdowns due to voltage sags causing large induction motors to trip, either by undervoltage or by overcurrent relays, sometimes by the mechanical protection. These unplanned shutdowns cost the plant tens of thousands of dollars per shutdown in addition to material damage costs, restart charges and any … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,120 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMultiresolution Analysis Based Effective Diagnosis of Induction MotorsHouda Ben Attia Sethom, Mediha Ajjabi GhedamsiProblem statement: Effective detection and localization of unbalance voltage supply affecting an induction motor may be compromised in presence of additionnal noise. Approach: In order to overcome the non possibility of the default detection and localization in presence of noise, the use of the discrete wavelet transform and especially the MultiResolution Analysis algorithm, to remove efficiently the noise associated to … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 20 Feb 2012 · 8,102 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleOn the Influence of Stator Slot shape on the Energy Conservation Associated with the Submersible Induction MotorsM. Sundaram, P. NavaneethanProblem statement: A good design of Submersible Induction Motor is required to maintain maximum efficiency level. This can be achieved in one way by optimum design of magnetic circuit. The magnetic circuit of an Induction Motor is formed by the combination of Stator core, Rotor core and air gap. In applications like Submersible Motor Pumps, the air gap cannot be … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynchronous Generator Disturbance Provoked by Induction Motor StartingS. P.Y. Santos, E. Delbone, E. F. Carvalho, L. N. MartinsProblem statement: This study presented an alternative procedure for the starting of large Inductions Motors (IM) in isolated generation systems. Approach: In isolated generation systems on stand-by or base load, the starting of the IM provoked sags frequently beyond the ability of the other consumers in the plant to stand. Manufacturers' solutions always recommend a supersized generator to decrease transient … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 6,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Development of an Intelligent Control by Using Bee Colony Optimization TechniqueS. Tiacharoen, T. ChatchanayuenyongProblem statement: In the modern industrial manufacturing system, the efficiency of machine control is essential to reduce waste and increase the output. Most of the manufacturing machines employ an induction motor in their driving system. A number of induction motors must be controlled during machine operation. The more accurately these motors are controlled the higher is the quality of the … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 4 Aug 2012 · 6,806 accessesView PDFCite
