  • 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 ...


  • 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 ...

  • 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 ...

  • Case Study: Developing a retrofit solution for Mitsubishi turbines

    RNRG’s product development team is always looking for ways to make customers’ lives easier. Our favorite type of design challenge is when we we get to collaborate directly with customers to solve an immediate issue. We recently embarked on ...

  • 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 ...

  • 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 ...

  • Influence of exogenous and endogenous factors on the exergy analysis of 3–column array wind farm

    Influence of exogenous and endogenous factors on the exergy analysis of 3 column array wind farm for two different layouts are highlighted in this paper. Nine turbines were placed in two different layouts to analyse the influence of exogenous factors such as wind velocity, wind direction, wind distribution and distance between turbines. Endogenous factors considered were diameter of rotor, hub ...

  • An experimental investigation of a solar/wind 4 kW micro generation system and T–1000 1.2 kW PEM fuel cell

    Hybrid system inclusive of renewable energy may be a key component for the solution of global warming, poor air quality, economic dependence, reducing–dwindling reserves of fossil fuels and also carbon tax in Australia. Firstly, this paper describes the experimental setup of wind/solar 4 kW micro generation system, examines the energy produced and various readings of monthly, weekly, daily and ...

  • Renewable energies: between climate protection and nature conservation?

    The use of renewable energies is considered as a key strategy for achieving global CO2-reduction targets. In countries like Germany, where policy support programmes stimulated a dynamic growth of renewables, we had to observe also increasing public concern towards the impacts from RES technologies – in particular wind turbines – on ecosystems and the natural scenery, leading to the question ...

  • Rising offshore plant capacities lead to greater data-based O&M gains

    The growing size of offshore wind farms provides greater scope for data optimisation during Operations and Maintenance, while software solutions can also help mitigate risk during the development phase, Marcus Ihle, Senior Consultant at Outsmart, said. Further gains could be made if operators share more data from their growing databases with other plant owners, Ihle said. The ...

  • UK offshore load factors accelerate on tech breakthroughs: 10-year study

    UK offshore load factors accelerate on tech breakthroughs: 10-year study The Crown Estate’s Offshore Wind Operational report 2015 shows there has been a gradual increase in the load factor for the UK fleet since 2004 on the back of more productive wind turbines, wind farms being built at windier sites and improved plant availability. The Crown Estate manages UK sovereign ...

  • Sustainable power and innovation provide clean drinking water and energy

    In many areas in Kenya, access to clean drinking water is lacking. About 88% of the population must travel long distances to get to the nearest source of clean water or is forced to drink contaminated water. Children in particular suffer from waterborne diseases. Systems Provide Energy-Independent Water Treatment To try to provide a long-lasting solution for the drinking water needs ...

  • Why Rare Earth Recycling is Rare (and What can We Do About it)

    Earbuds, touch screens, CFLs with a warm glow, rechargeable batteries and power windows: Most of us take these things for granted. When we do, we also take for granted a group of elements called rare earth metals, whose special electronic and magnetic properties make them a key component of many 21st century technologies. These 17 elements are actually plentiful enough — you probably have ...
