Comparing the network performance between the installation of DG and compensating capacitor using EP
(Universiti Teknologi MARA (UiTM), 2008-08)Rapid industrialization and population growth have resulted in an escalation in the electrical power demand. Due to limited area and slow progress in network expansion some regions have become high density load areas, for ... -
Transmission loss allocation in deregulated power system using the hybrid genetic algorithm-support vector machine technique
(Cyber Journals, 2011-01)This paper proposes a new method to trace the transmission loss in deregulated power system by incorporating the Genetic Algorithm (GA) and Least Squares Support Vector Machine (LS-SVM). The idea is to use GA to find ... -
Evaluation of the localised loss transformer core lamination
(Asian Network for Scientific Information, 2010)The magnetic flux has to change its direction at butt-joint meanwhile at butt-joint occur the hot spot. The hot spot can be measure using thermistor in term gradient temperature. These papers describe the result of measurement ... -
Current perspective of the renewable energy development in Malaysia
(Elsevier Ltd., 2011-02)It is estimated that oil reserves will not last very much longer; thus, a switch to alternative energy solutions is crucial. The Malaysian government has already prepared to face the situation decades before. Many policies ... -
Photoinduced effects in l-alanine crystals
(Elsevier B.V., 2010-09-30)An influence of the cw laser treatment at 660 nm (red), 532 nm (green) and 405 nm (blue) wavelengths on the absorption in l-alanine crystals was studied. We have established that increasing time of illumination for red ... -
Small-signal AC modeling technique of Buck converter with DSP based Proportional-Integral-Derivative (PID) controller
(IEEE, 2009-12-16)Control applications of switched mode power supplies have been widely explored. The main objective of research and development (R&D) in this field has always been to find the simplest method to analyze and model the DC/DC ... -
Computer designed solar concentrator
(International Association of Science and Technology for Development (IASTED)/ACTA Press, 2007)This paper discusses a computer designed optical concentrator, which is providing efficient solar energy transfer to a Stirling Engine. The receiver can make line focusing onto the absorber of Stirling engine located at ... -
Tracking error analysis of a rotation-elevation mode heliostat
(Science Publications, 2007)For the past few years, great efforts have been done in improving the tracking accuracy of a newly proposed rotation-elevation tracking mode heliostat. A special simulation program has been developed to systematically ... -
Tracing generators' output in transmission open access
(Institute of Electrical and Electronics Engineering (IEEE), 2007-12)Over the past few years, the electric power utility industries around the world have experienced a strong drive towards deregulation. Based on the experience of deregulation of the communication, natural gas and airline ... -
Simplification of sun tracking mode to gain high concentration solar energy
(Science Publications, 2007)Power 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 ... -
Discrimination and classification of Eurycoma longifolia Jack in medicinal foods by means of a DSP-based electronic taste sensor
(SAGE Publications, 2004)Eurycoma longifolia Jack (ELJ), better known as Malaysian Ginseng, is fast becoming popular due to its efficacy as a general health and testosterone booster, and for its known aphrodisiac properties. With the growing ... -
The effects of harmonic components on transformer losses of sinusoidal source supplying non-linear loads
(Science Publications, 2006)An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Sinusoidalare major components in power systems. The increased losses due to harmonic distortion can ... -
Design of a single-phase rectifier with improved power factor and low THD using boost converter technique
(Science Publications, 2006)The method of using Boost type of converter was proposed for a 300W single-phase rectifier in this paper. By designing the necessary techniques and methodology, the overall Power Factor (PF) and Total Harmonic Distortion ... -
