  • Deep research on China wind turbine blade industry

    It was a professional and depth research report on China Wind Turbine Blade industry. Since 2009, the price of China's wind turbine blade has decreased substantially, which is a big challenge for these new entrants and existing wind turbine blade manufacturers. On the development trends of current domestic wind power equipment market, supply and demand tension has been greatly eased with the ...


  • Tillsonburg: From tobacco farming to building wind turbine blades

    The story of Tillsonburg is probably close to the ideal example of what the Ontario government was looking for when it enacted the Green Energy Act in 2009. A small town of 16,000 people in southwestern Ontario, Tillsonburg’s history is famously celebrated in Stomping Tom Connor’s distinctive drawl when he sung about making seven ...

  • 2nd Generation Wind Turbines

    2nd generation wind turbines are better, more effective, than its predecessor, and succeed in generating more electricity with smaller wind volumes. These wind turbines incorporate two newer technologies, that make them more efficient. Self starting vertical blades and magnetically suspended bearings, which makes them superior to any other. The self starting vertical blades provide advantages ...

  • The VGOT Darrieus wind turbine

    We present the actual state of development of a non-conventional new vertical-axis wind turbine. The concepts introduced here involve the constructive aspects of variable-geometry oval-trajectory (VGOT) Darrieus wind turbines. The key feature of a VGOT machine is that each blade slides over rails mounted on a wagon instead of rotating around a central vertical axis. Each wagon contains its own ...

  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Reducing avian collisions with wind turbines

    Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical ...

  • Animation: How Wind Turbines Work

    The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects. By the end of the 19th century, wind energy took on a whole new meaning as engineers ...

  • Comparative study of the performances of twisted two-bladed and three-bladed airfoil shaped H-Darrieus turbines by computational and experimental methods

    The vertical axis H-Darrieus turbines are simple in construction, self-starting, omni-directional, and self-regulating at all wind speeds. A comparative study of the performances of twisted two-bladed and three-bladed airfoil shaped H-Darrieus turbines was made. The models of the turbines were designed, fabricated, and tested in a subsonic wind tunnel. The power coefficients (C ...

  • Finite element structural study of the VGOT wind turbine

    We analyse the implementation of the finite element method to simulate the structural behaviour of the blade-wagons of variable-geometry oval-trajectory (VGOT) Darrieus wind turbines. The key feature of a VGOT machine is that each blade, instead of rotating around a central vertical axis, slides over rails mounted on a wagon formed by a tubular reticulated structure supported by standard train ...

  • Adoption hurdles and challenges with small wind turbines

    Adoption Hurdles and Challenges with Small Wind Turbines Wind energy is very promising. It can be harvested without any costs, and like solar panels, wind turbines are environmentally-friendly. However, such machines are not living up to their potential. Some users have reported low efficiency rates, unpredictable performance and costly adoption barriers. ...

  • Performance estimation of HAWT blade using NACA airfoils

    Wind energy is one of the developing resources of renewable energy. In order to increase the use of wind energy, development of wind turbine blade with higher power coefficient plays a vital role. The work being presented here is to give new design of blade for VESTAS V82–1.65MW (HAWT). In this work, NACA airfoils are used for the determination of aerodynamic performance characteristics of ...

  • 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 ...

  • Evolution of collaborative innovation network in China's wind turbine manufacturing industry

    This paper studies the 'catching–up' process of China's emerging wind turbine manufacturing ecosystem, and analyses the dynamics of the shifting collaborative innovation network for the period 1980–2011. We have focused on the leading wind turbine manufacturers [i.e., manufacturers of entire wind turbine system integrators (EWSIs)], as well as manufacturers of the turbines' sub–ecosystems (i.e., ...

  • Medium scale wind turbine near colchester case study

    In September 2009 planning permission was granted for a medium scale wind turbine on a farm near Colchester. The wind turbine, which has a maximum blade tip height of 49m, was installed in Spring 2010. Green Dimension undertook the feasibility work, stakeholder consultations and the preparation of the successful planning application on behalf of the farmer. Key stakeholders included ...

  • A combined electro-mechanical control technique for dynamic voltage regulation of a stand-alone wind turbine generator

    This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load voltage regulation. Speed regulation is achieved by adjusting the pitch angle of the turbine blades. ...

  • Wind power status, barriers, and opportunities

    In the wake of the oil crisis in the early 1970s, governments around the world were anxious to diversify energy supply away from fossil sources, and so harnessing the wind was seen as an important component of this policy initiative. A decade of research saw a Danish designemerge as the industry standard: the three-bladed, horizontal axis, upwind machine. A modern wind turbine comprises a tubular ...

  • Community Wind Power for Renewable Income

    CONSIDERING its incredible history and environmental benefits, wind power is one of the most underutilized sources of renewable energy. Stretching back as early as 200 BC, communities have been harvesting the wind for power. However, the scale and popularity of wind power is only now starting to reach critical mass as concerns of climate change rise and energy usage continues to soar. While ...

  • What’s the Future of R&D in the Wind Industry?

    When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...
