  • Case study - Use of the Nor848A acoustic camera on wind turbines

    The acoustic camera system Nor848 is a powerful tool to investigate noise sources. In realtime you listen to a beamformed audio signal so that you can hear individual sources one by one. Immediately you can identify the strongest over all noise source in a multisource environment, and you can do the same analysis for single frequencies, 1/3 or 1/1 octave bands or any given frequency range. This ...

  • Africa’s green energy challenge: Mega projects, off-grid or somewhere in between?

    South of the Sahara, getting electricity to 620 million people may require an all-of-the-above strategy. A 310-megawatt wind farm sprouting up in a remote, barren landscape near Lake Turkana in northern Kenya has the clean energy world buzzing — and for good reason. Africa’s largest wind farm, with 365 towering turbines, is creating more than 500 stable jobs in an ...

  • Does Wind Turbine Blade Length Really Matter?

    Simply put: Longer wind turbine blade length means greater power production. Blades capture the wind which forces the rotation of the rotor; longer blades means more area for the wind to push against, which means greater force and rotational power. However, how much difference does blade length make overall, in comparison to other factors? There is a standard formula that can be used to apply the ...

  • How do you bring electricity to 620 million people?

    Sub-Saharan Africa needs a more reliable energy supply. The way it chooses to meet that need will affect the entire planet. In South Africa, major cities are subject to regular power outages as electric utility Eskom periodically shuts down parts of its distribution system to take the pressure off the aging national grid. Whole areas of Cape Town and Johannesburg are without power ...

  • Better grid interconnection essential for wind energy growth in Europe

    With a dramatic fall-off in government support for wind power in one of its superpower countries, Spain, Europe’s wind industry is concerned. Marc Height reports from Barcelona. From a wind industry leader to a focus of concern for the industry in Europe, things have changed in Spain pretty quickly. In January, the country made headlines by becoming the first in the world to source the ...

  • Wind power prefeasibility study for agricultural applications in Kerman, Iran: a case study

    In the present paper, wind characteristics have been analysed for three agricultural sectors in Kerman (30°15'N,56°58'E), Iran. Wind data collected from three synoptic stations for the period of July 2006 to June 2011 at the height of 40 m has been used to study the monthly and annual wind energy potential. Two statistical methods (Meteorological and Weibull) have been applied to ...

  • Generation Gap: Wind Opens Big Lead over Nuclear in China

    In China, wind power is leaving nuclear behind. Electricity output from China’s wind farms exceeded that from its nuclear plants for the first time in 2012, by a narrow margin. Then in 2013, wind pulled away—outdoing nuclear by 22 percent. The 135 terawatt-hours of ...

  • Soil Drying Beside Buried Cable

    Wind turbine farms are becoming an acceptable and common form of energy. Part of their construction includes buried cables to deliver the generated power from the wind turbines back to a station and ultimately into the power grid. One potential design consideration is evaluating the heat generated when an electric current passes through the cable.The rate of heat generation may cause the ...
