  • Small Wind Turbines tested: “Fortis Montana best performance”

    The market for commercial wind turbines is maturing even as they get bigger and bigger, but the market for small wind turbines is quite young, with some people comparing it to the car industry early in the 19th century. Although some manufacturers have been in the business for over two decades, most suppliers are from this millennium. And that shows. As in most immature markets, there are ...

    In this collaborative activity Partners will undertake research and develop economically viable, reliable small wind turbines for remote power systems located away from the electricity grid as well as for connection into the grid. This project will study small wind turbine operation in a wide range of situations, with the goals of improving design, developing safety methodologies and reducing ...

  • Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica

    Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

  • Small wind turbine emulator with armature controlled separately excited DC motor via analogue electronic circuit

    In this paper, a small wind turbine emulator (WTE) using separately excited DC motor is modelled, designed, simulated, implemented and tested. A 1 HP separately excited DC motor is used to emulate the characteristics of the rotor of small wind turbine. The DC motor is driven by a thyristor bridge with closed–loop cascaded PI controller for armature control. A separately excited DC generator with ...

  • How much wind is needed to power a home turbine?

    First do you have what it takes? Whether you are considering a small rooftop unit or a large residential turbine you need to know how much wind power is in your area. Wind resource maps, published by the US Department of Energy show airflow speeds at 50 meters (150 feet) above the ground and are a great resource in deciding if you are in a viable location. That's great if you are installing a ...

  • Hansen transmissions - wind turbine gearbox testing with PULSE

    The Wind Energy Market Wind energy is one of the fastest growing power generation technologies. The level of annual installed capacity has grown at an average rate of 27.6% p.a. for the past five years. High fuel prices and increased focus on global warming and renewable energy resources have contrib- uted to an increased investment in the development of wind technology over the last three ...

  • 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 ...

  • 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 ...

  • Design of simulator for modelling of wind turbine and transfer of maximum power using buck-boost converter

    A small wind turbine simulator based on a separately excited DC motor-permanent magnet synchronous generator (PMSG) set has been proposed to evaluate the performance of the small wind turbine model. A DC shunt motor is used to produce varying aerodynamic power by varying field current with the help of an IGBT switch. The simulator is an equivalent gearless wind turbine model that fluctuate ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Wind power growth in the US

    Last year was a banner year for renewable energy in the United States, especially for the wind industry. As the recent REN21 Renewables 2007 Global Status Report highlights, the industry broke all past global records, installing 5,244 megawatts (MW) of new wind energy capacity in 2007, or 30 percent of all new U.S. capacity added. This brings the cumulative national total close to 17,000 ...

  • 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 ...

  • 2013 to be Record Year for Offshore Wind

    Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months. Fifteen countries host some 6,500 megawatts of offshore wind capacity. Before the year is out, the world total should exceed 7,100 megawatts. Although ...

  • On the application of miniSoDAR technology to wind energy

    Introduction In the late 1990’s wind turbines with nacelle heights exceeding 60 meters were introduced to the wind energy community. Initially, wind prospecting and siting studies continued to use 50-meter wind towers and extrapolate the measurement to the nacelle heights. It was quickly determined that this approach was not sufficient for the placement of these tall turbines. The next ...

  • Wind Energy Technologies: Technology, Market and Costs

    Technology Overview   These large wind turbines turn Midwestern wind into utility electricity. Wind turbines convert the power in the wind into electricity. By extracting the kinetic energy in the wind, wind turbines generate mechanical power. In the past, mechanical wind machines were widely used for specific tasks, such as pumping water or grinding grain. Today, wind ...

  • 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 ...

  • Innovation risk slows offshore wind foundation development

    As offshore wind technology develops ever more gigantic machines further from shore into deeper waters, it is common wisdom that new foundation technologies are needed. But are they? Monopile, and some jacket foundations, still dominate the offshore wind market in commercial operation. Prototype floating foundations are performing well in demo or pilot projects, but scaling up is only ...
