Research ArticleOpen accessEvery word in the titleSTUDY OF THE LIGHTNING IMPACT ON THE WIND-TURBINEDib Djalel, Guebla Abdallah, Labar HocineGenerally, lightning damage has mainly been to home appliances and telephones, Towers and power transmission and generation equipment mal functions and damage due to strikes on power lines. With the adoption of wind power generation equipment, however, lightning damage is also increasing in this area. Through his dimensional characteristics and the wind power system is more exposed in the nature … …Energy Research Journal, Vol. 5, Issue 1 · 16 Oct 2014 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Critical Review of Global Wind Power GenerationT. Ahilan, Dr. K.P. Mohammed, Dr. S. ArumughamThis research begins with an overview of wind development and installation-related trends, including trends in capacity growth. Development of wind power has reached a level of maturity, which could be taken upon for further novelty and growth in meeting the future energy needs in much greater proportion. Current research techniques are producing stronger, lighter and more efficient blades for the … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,486 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Protection through Nuclear EnergyFlorian Ion T. Petrescu, Antonio Apicella, Relly Victoria V. Petrescu et al.Environmental protection through implementation of green energies is progressively becoming a daily reality. Numerous sources of green energy were introduced in recent years. Although this process initially started with difficulties, it finally resulted in an acceleration and implementation of new green energy technologies. Nonetheless, new major obstacles are emerging. The most worldwide difficult obstacle encountered, especially for wind and photovoltaic … …American Journal of Applied Sciences, Vol. 13, Issue 9 · 28 Sep 2016 · 12,511 accessesView PDFCite
EditorialOpen accessIn the abstractAn Opportunity for the Agricultural Sector: The Renewable Energy SourcesRiccardo Testa, Salvatore TudiscaToday, among the most important issue for energy decisions by policymakers, there are security challenges and environmental impacts on climate change and economic aspects. Since the seventies, in fact, global warming and environmental issues have had an increasing importance in international debate, attracting the attention of several scientific studies (Landi and Benelli, 2016). Many of these studies denoted that over … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 6 Sep 2016 · 8,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractNonlinear 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 · 7,568 accessesView PDFCite
EditorialOpen accessIn the abstractON THE CHALLENGES OF THE USE AND INTEGRATION OF RENEWABLE ENERGY SOURCESMariano MartínOverview: Although renewable energy sources are plentiful, their availability is highly volatile in time and distributed across regions while and the processes that transform them into useful power or chemicals are underdeveloped. In this work we discuss on the scope for the use and integration of renewable energy sources and the future development of the alternatives. Energy, the sources and … …Energy Research Journal, Vol. 5, Issue 1 · 11 Sep 2014 · 7,543 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION 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 · 7,445 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Closed Loop LCL-T Resonant DC-to-DC Converter Using Low Cost Embedded ControllerM. Annamalai, M. Vijaya KumarThe aim of this study is to simulate and implement open loop and closed loop controlled DC-DC converter for stand-alone wind energy system. Wind turbines, however, are not always very efficient in the wind speeds that are most common to a region. Typically, wind energy systems are designed to be highly efficient in high wind speed and have a cut-off … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 4 · 6 Feb 2013 · 7,592 accessesView PDFCite

Research ArticleOpen accessIn the abstractSimulation of Airflow and Aerodynamic Forces Acting on a Rotating Turbine VentilatorA.S. Farahani, N.M. Adam, M.K.A. AriffinProblem statement: Rotating turbine ventilators were generally found in most countries. They were simple in structure, light in weight and cheap to install. It was quite surprising that, the aerodynamics of this common device had not been numerically examined and the design process of most of these ventilators had developed progressively through trial and error methods. Approach: This study was … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,719 accessesView PDFCite
