Research ArticleOpen accessPhrase in the titleStatistical Modelling of Botswana’s Monthly Maximum Wind Speed using a Four-Parameter Kappa DistributionOliver Moses, Bhagabat Prasad ParidaWind speed modelling has been key to many environmental and engineering applications, particularly in environmentally friendly wind power generation to meet energy demands. Efficient assessment of wind speed at different recurrence intervals requires the choice of a suitable statistical distribution and an unbiased method of parameter estimation. This study suggests the use of a four parameter Kappa distribution, with its … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 22 Jun 2016 · 7,546 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEVALUATION OF THE ADEQUACY OF THE WIND SPEED EXTRAPOLATION LAWS FOR TWO DIFFERENT ROUGHNESS METEOROLOGICAL SITESDalila Khalfa, Abdelouaheb Benretem, Lazher Herous, Issam MeghlaouiIncreasing knowledge on wind shear models to strengthen their reliability appears as a crucial issue, markedly for energy investors to accurately predict the average wind speed at different turbine hub heights and thus the expected wind energy output. This is particularly helpful during the feasibility study to abate the costs of a wind power project. The extrapolation laws were found … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 7,439 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA New Design of Blade for Small Horizontal-Axis Wind Turbine with Low Wind Speed OperationParamet Pathike, Thanad Katpradit, Pradit Terdtoon, Phrut SakulchangsatjataiIn Thailand, the average wind speed throughout the country is comparatively low for normally-available wind turbine. Designing of a new blade suitable for applications in the average wind speed of 3-7 m sec-1 is, thus, a main objective of this study. High torque has to be obtained properly to generate electricity. In order to design and evaluate performance, our mechanical … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,063 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Meteorological Tower Based Wind Speed Prediction Model Using Fuzzy LogicSardar Maran Poongavanam, Ponnusamy RamalingamA number of wind speed prediction methods are available for estimating wind energy availability. In recent years there is a lot of research works carried out to predict wind speed by using mathematical and soft computing techniques. In this study the wind speed profile at different heights are predicted with the available meteorological tower data. The wind speed data at … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 7 May 2013 · 6,866 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,546 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleNonlinear Control of Variable wind Speed Conversion System Based on a Squirrel Cage Induction Generator (SCIG)Abouobaida HassanThis study presents a control strategy for a Squirrel Cage Induction Generator (SCIG)-based wind energy conversion system. Control strategies of the AC/DC/AC converter is presented along with the mathematical modeling of the employed configuration. The maximum power point extraction of the wind turbine is addressed along with the proposed strategy. The backstepping approach is introduced to control the generator speed … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 25 Jun 2015 · 7,565 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePitch Angle Control of Variable Speed Wind TurbineYousif El-TousThe aim of this study is to design a simple controller to maximize the extracted energy of wind turbines. In this study the pitch angle control of variable speed wind turbine is investigated. In particular, it concentrates on the extraction of maximum available energy, reduction of torque and output power variations, which gives stresses in the gearbox and mechanical structure. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 8,735 accessesView PDFCite

The specific atmospheric condition of this region, especially high-speed and continuous winds, can provide the necessary condition for Electricity generation from wind power. 120-day winds of Sistan region are one of the renewable energy sources in the province, which has been neglected in recent … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 6 May 2020 · 6,823 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMathematical Analysis of How the Electrical Training Center Site is Affected by Air PollutionBassam A. Al-HelouThe study has come to the result that the monitoring site at the Electrical Training Centre (ETC) at Al-Hashimyeh town is exposed to grave pollution that goes beyond Jordanian standards of the ambient air. It has, indeed, shown that Sulfur dioxide (SO2) exceeds the limits and its seasonal concentration matches forward with the average wind speed. SO2 concentration reaches its … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 3 Sep 2012 · 7,111 accessesView PDFCite
