Diagnosis of MV oil filled cable terminations with X-ray imaging and infrared (IR) thermography
(Science Publications, 2007)
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 ...
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 ...
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 ...
Power flow tracing via modified proportional tree method
(Universiti Malaysia Perlis (UniMAP), 2008-03-08)
Tracing the flow of electricity becomes an important issue under deregulation system. It is more complicated compared to other fields due to norlinear nature of power flow and specific properties of electricity. Since the ...
Determination of reactive power flow in deregulated transmission system
(Institut Teknologi Brunei, 2008-11-03)
The electricity industry throughout the world, which has long been dominated by vertically integrated utilities, is undergoing enormous changes. Deregulation has necessitates the decomposition of three components of electric ...
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 reactive power flow and loss in electric power systems
(Regional Energy Resources Information Center (RERIC), Asian Institute of Technology (AIT), 2009-03)
This paper suggests a systematic method to trace the reactive power flow and loss named as Proportional Tree Method (PTM). From the power flow solution, the test system is modeled conceptually like a tree, where the reactive ...
Comparion methods for determining generators shares in loads, line flows and losses for transmission open access
(Universiti Teknologi Mara (UiTM), 2008-06-04)
In transmission open access, determining generators' share in loads, line flows and losses have become an important issue, due to the complexity of electrical transmission system, it is not straightforward to map out tin ...
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 ...
Optimal allocation and sizing of DG in distribution system using evolutionary programming technique
(Universiti Teknologi MARA (UiTM), 2008-06-04)
In recent years, distributed generation (DG) installation has shown an increasing growth in the distribution networks around the world due to the raise in promotion towards utilization of renewable energy resources and ...
