Siemens Energy has uprated its D3 onshore platform wind turbines. The new SWT-3.2-101, SWT-3.2-108 and SWT-3.2-113 machines feature improved performance from 3.0 to 3.2 megawatts (MW) and implement the sum of design and operational experiences. The uprated products will enter serial production by the end of 2014. They will be available with 101 and 108 meter rotors for IEC class IA sites, and a 113 meter rotor for IEC class IIA sites. The 3 MW version will remain available for project sites with lower wind speeds.
Simplicity and efficiency were the key words when Siemens developed its first commercial direct drive turbine in 2009. Following five years of experience and a large number of D3 wind turbines installed worldwide, the fundamental approach remains the same, but the technology continues to be refined. The uprated Siemens D3 wind turbines represent a classical wind turbine evolution, combining the reliability of a proven and tested concept with cutting edge technology development. Improvements in the turbine control system and increased efficiency through the use of stronger magnets are the key factors that allowed Siemens to get more power out of the D3 drivetrain.
The uprating underlines the structural reserves already found in the construction of Siemens' gearless wind turbines. "One important goal of our development work is to utilize innovation to further tap the technical potential of our products," says Henrik Stiesdal, CTO of Siemens Wind Power. "Rotors, structures and performance have been tested intensively to simulate more than 20 years of lifetime stress. This resulted in a new product generation which offers the reliability of the predecessor while delivering up to 4 percent more energy yield."
Wind power and the associated service activities are part of Siemens' Environmental Portfolio. Around 43 percent of the company's revenues are generated by green products and solutions. That makes Siemens one of the world's leading providers of eco-friendly technology.

A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.
The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...
A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).
Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...
In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.
These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...
Bacteria do not cease to amaze us with their survival strategies. A research team from the University of Basel's Biozentrum has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In the current issue of “Cell Reports”, the scientists describe the mechanism of action and also explain why their discovery provides new insights into the evolution of pathogens.
For many poisons there are antidotes which neutralize their toxic effect. Toxin-antitoxin systems in bacteria work in a similar manner: As long as a cell...
It comes when called, bringing care utensils with it and recording how they are used: Fraunhofer IPA is developing an intelligent care cart that provides care staff with physical and informational support in their day-to-day work. The scientists at Fraunhofer IPA have now completed a first prototype. In doing so, they are continuing in their efforts to improve working conditions in the care sector and are developing solutions designed to address the challenges of demographic change.
Technical assistance systems can improve the difficult working conditions in residential nursing homes and hospitals by helping the staff in their work and...
