Performace of wind turbine based on wind speed data and turbine tower height in Kangar, Northern Malaysia
(Australian Journal of Basic and Applied Sciences, 2011-07)
This paper presents an analysis of the wind speed characteristic in Kangar, Northern Malaysia. The Weibull distribution function is applied to analyze the wind speed characteristic and used to calculate the wind power ...
Fabrication and investigation of copper rotor bar on 0.5HP induction Motor-A performance and economical study
(Australian Journal of Basic and Applied Sciences, 2011-05)
The paper deals with the fabrication of copper rotor bars for 0.5HP induction motor and then comparing it with the existing aluminium rotor bars. From this experiment the rotors are compared in terms of efficiency increment ...
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 ...
Comparison of copper rotor bars with aluminium rotor bars using FEM software - A performance evaluation
(Institute of Electrical and Electronics Engineering (IEEE), 2009-12-28)
It is generally assumed that copper rotor bars can outstand aluminium rotor bars in terms of better performance in losses reduction or money saving. This paper presents the comparison of the aluminium rotor bar and copper ...
Optimization of current total harmonic distortion on three-level transformerless photovoltaic inverter
(Elsevier Ltd., 2012)
This paper presents a new topology of three-level transformerless photovoltaic (PV) inverter. It consists of three main circuits; they are a pulse driver circuit, a full bridge inverter circuit and a power factor correction ...
Improvement of induction machine performance using power factor correction
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-21)
In this paper, a new approach to improve power factor (PF) and reduced total harmonic distortion (THDi) is generated by a single phase induction motor is proposed. By designing the necessary technique and methodology, the ...
