A giant wind-powered generator

14.10.2003


The new TWT-1650 wind-powered generator presented in Pamplona has 36-metre vanes which, in a circular movement, sweep an area greater than that of a football pitch and which can withstand extremes of weather, including winds of up to 110 kilometres an hour.



This device, made by Grupo Mtorres in collaboration with the Institute for the Diversification and Saving of Energy (IDAE), is beginning its commercial life, after three years of tests.

The new model, with a power of 1,650 kilowatts, uses a multipolar technology and distinguishes itself from conventional machines in that mechanical elements have been replaced by electronic ones, i.e. the "multiplier" which reproduced wind power as electricity has been replaced and 60 magnets have been installed in the "rotors" (the part that gyrates).


The system has environmental advantages, as well as ones of costs and energy yield, given that the mechanical part of wind-powered generators are the cause of 30% of the failures and errors in these machines. In other words, an important percentage of maintenance costs will disappear.

This is why a new wind park concept is considered: distributed energy generation, i.e. small installations with three to six machines and near the consumer and connected directly to the distribution grid.

This means less noise and less visual impact on mountain ridges and by the migratory routes for birds, as well as eliminating the use of lubricant oils which the machinery mechanics needed (300 litres per year).

The disadvantages of this technological development is that the wind-powered generator has more weight and volume (this Group is even considering achieving 50-metre long vanes made up of carbon-fibre modules) and the initial investment and costs is greater than the conventional models.

Energetically the machine – which has a computer which controls what is done at any moment depending on wind direction – better withstands troughs in the grid and is therefore more reliable in power cut situations.

The Mtorres Group and the German company, Enercom are the only enterprises developing this technology.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
