  • Wind Turbine Systems in China

    Demand for wind turbine systems in China is forecast to rise 5.3 percent annually through 2013 to ¥62.3 billion. Increases will be driven by a variety of factors, primary among them government policies that encourage the use of renewable and nonpolluting electric power sources such as wind. Such policies include favorable pricing of wind power generated from wind farms, tax incentives and ...


  • Power Electronics for Wind Turbines

    In 2011, almost 44GW of wind energy has been installed in the world and half of it was in China. Each years’ results are greater than predictions, and it has been so for the last 10 years. But we envision a slow down in this growth, fully explained in this report: 22% annual growth is huge. Based on the history, we believe the market will stay between 15% and 20% growth until 2015. Compared ...


  • New wind turbines at pixel revealed

    Grocon today unveiled new wind turbine technology atop its carbon neutral Pixel building in Carlton.

  • `Anti-noise` silences wind turbines

    If wind energy converters are located anywhere near a residential area, they must never become too noisy even in high winds. Most such power units try to go easy on their neighbors' ears, but even the most careful design cannot prevent noise from arising at times: One source is the motion of the rotor blades, another is the cogwheels that produce vibrations in the gearbox. These are relayed to ...
