An alternative approach to solar and grid-connected hybrid electricity for homes and buildings in Malaysia
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper presents the proposal of a solar and
grid-connected hybrid electricity system for homes and
also buildings. A new concept of using a DC motor
and synchronous generator as an electromechanical
inverter is ...
Current transformer reaction with total harmonic distortion
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Current transformer (CT) has a critical role in
protective and measurement devices used in both the
industrial and the utility worlds. However, the used of
current transformer in harmonic condition brings
some effects ...
The effect of different stator slot size on the stator copper loss
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
The input power to an induction motor is in the form of three phase electric voltages and currents. The first losses encountered in the machine are I2R losses in the stator winding. The stator copper loss occurs when the ...
Flux pattern in 1000 kVA 11/.433 kV distribution transformer core to sinusoidal wave
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
A study was conducted using sinusoidal waveform
to capture flux pattern in CRGO M5 material in a
1000kVA 11kV 3 phase transformer core. It is found
that it takes about 180⁰ electrical degree cycle for a
pool of flux ...
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 ...
Potential of solar radiation and wind speed for photovoltaic and wind power hybrid generation in Perlis, Northern Malaysia
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)
This paper presents analysis of the solar radiation and wind speed characteristics in Perlis, Northern Malaysia for the year of 2006. The characteristics consist of daily and annual mean solar radiation and wind speed. ...
Measurement of overall power loss for different three phase 100kVA transformer core material
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)
This paper discussed result of an investigation towards the effect of using two different Cold Rolled Grain-Oriented (CRGO) Silicon Iron material to the 100kVA three phase distribution transformer. This experiment used M4 ...
