  • 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 ...

  • Are wind turbines economically viable in Britain?

    If Britain establishes wind energy as their main energy source, they will be able to create a large number of new job opportunities. This can provide a huge influx of job opportunities in the short run since the implementation of wind turbines require a lot of manpower. Moreover, the maintenance of these wind farms can give life to a considerable amount of sustainable jobs. Monitoring the wind ...

  • 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 ...

  • Lightning protection optimization for large wind turbines

    Electro-magnetic fields adjacent to the lightning current path in wind turbine generators are analyzed. The method of moments is used to analytically describe the transient distributed electro-magnetic field caused by a lightning strike. A simulation tool using the method of moments is presented. The electromagnetic field distribution during a lightning strike in a wind turbine hub is analyzed in ...


  • 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. ...

  • 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 ...

  • Dynamic validated model of a DFIG wind turbine

    This paper presents the development and qualitative validation of a doubly-fed induction generator (DFIG) wind turbine model that is represented in terms of behaviour equations of each of the subsystems, mainly the turbine rotor, the drive train, the induction generator, the power converters and associated control systems and a protection system. Simulation results obtained from the models are ...

  • 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 ...

  • Sub and super-synchronous wind turbine-doubly fed induction generator system implemented as an active power filter

    This paper deals with a wind energy conversion system (WECS), based on a doubly fed induction generator (DFIG) and an electromechanical active power filter (APF). The objective is to respond simultaneously to electric energy requirement and power quality concerns. The proposed WECS is able not only to track the maximum power point of the wind energy but also to dampen harmonic currents from the ...

  • Steady-state analysis of doubly fed induction generators for wind turbines using MATLAB

    A wind energy conversion system (WECS) differs from a conventional power system. The power output of a conventional power plant can be controlled whereas; the power output of a WECS depends on the wind. This nature of WECS makes it difficult for analysis, design and management. Various approaches have been developed to study the behaviour of WECS. In this paper, the steady-state characteristics ...

  • Modelling and control of a variable speed wind turbine driving doubly fed induction generator using three–level PWM converter

    The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two–pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the utilisation of three levels voltage ...

  • Variable susceptance excitation control for dynamic performance improvement of a stand-alone wind turbine induction generator system

    Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. Lacking control capability, such generation can contribute very little to network support. Wind turbines mostly do not take part in voltage and frequency control and if a disturbance occurs, the turbines may be disconnected and reconnected when normal operation has been resumed. From ...
