Investigation of power factor on harmonic effect due to types of voltage source
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper discussed about power factor on harmonic effect due to types of voltage source. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements ...
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 ...
Clear sky global solar irradiance on tilt angles of photovoltaic module in Perlis, Northern Malaysia
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-21)
The performance of a photovoltaic (PV) is highly influenced by its orientation and its tilt angle with the horizontal, due to the fact that both the orientation and tilt angle change the amount of solar radiation reaching ...
Combination of Hargreaves method and linear regression as a new method to estimate solar radiation in Perlis, Northern Malaysia
(Elsevier Ltd., 2011-11)
The best way to obtain the solar radiation data of a particular place of interest (POI) is to measure at the specific site continuously and accurately over the long term. However, due to financial, maintenance, calibration ...

Parameter determination of 0.5 hp induction motor based on load factor test - A case study
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-21)
The load can influence the efficiency of the induction motor. Even if the load has higher or less load factor, it can reduce the efficiency of an induction motor by several percentage. By knowing this, it is important that ...
Determination of power flow and loss allocation using superposition theory method
(Regional Energy Resources Information Center (RERIC), Asian Institute of Technology, 2008-03)
This paper discussed a method to determine power flow and loss from individual generator to particular load and line flows for transmission open access. Based on solved load flow, the method uses basic circuit theories ...
