Europe remains the hotbed for wind power's pioneering technology. In the sector of superconductive generators for wind turbines there are even three large-scale European funded projects:
and of course, EcoSwing. On the national level there are even quite more projects. All these projects certainly have different abitions and different approaches. However, the motivation is similar:
“The problem is that there is a limit for constructing with current technology,” says Iker Marino, an electrical engineer in the renewable energy and storage systems group at the Spanish applied-research organization Tecnalia Corporación Tecnológica and coordinator of Suprapower. “The weight of the top of the machine is too huge.”
This quote comes from a new article by Sam K. Moore, featured in the IEEE spectrum. The article provides a very readable and interesting comparison of these activities. It also introduces a non-superconducting contender called the magnetic pseudodirect drive (PDD), It’s a kind of magnetic gearing system in development at Magnomatics, based in Sheffield, England. Its next stage is a 500-kilowatt generator, which it will test on a dynamometer.
Superledende generator skal gøre vindmøllerne lettere

A superconducting generator will make wind turbines lighter. That is the essence of an article that was published by Bjørn Godske for Ingeniøren, a Danish weekly newspaper specialising in engineering topics.
This article has quite a number of technical facts and figures from the design and from the testing phase."It's really weight saving which means something when the generator needs to be lifted up to 100 meters," says Jesper Hansen from our project partner Envision Ennergy

Big Rotor on a Diet...

...this is what science reporter Frank Grotelüschen commented on the EcoSwing generator when he did a series of interviews for the Deutsche Welle (DW). DW is Germany's public international broadcaster with service is available in 30 languages.
"Higher, bigger and more power. Wind turbines have become so big and heavy that transport and installationare becoming increasingly difficult. The solution: significantly lighter and compact generators using high temperature superconductors. An EU project is creating the world's first superconducting wind turbine".
This is his take away after he had interviewed our project partners Werner Prusseit (THEVA), Jesper Hansen (Envision), and Jan Wenske (IWES)

EcoSwing Reports "Testing Complete"
Written on .
Bremerhaven, May 22, 2018 - The ground-based tests at IWES are complete and lots of testing data were evaluated. The experts at Fraunhofer IWES confirm that the EcoSwing concept showed good results along with good functionality of the overall DyNaLab integration. A first opportunity into detailed test results is the 9th Meeting Session of the Association of German Engineers (VDI), see below for details.
"As a world's first, we stepped up in applying superconducting technology with the ambitious project EcoSwing. In order to reduce uncertainties, new technology needs testing under realistic conditions. IWES' DyNaLab provided the opportunity to test under definable conditions and gain reliable results," says Jesper Hansen, Senior Project Manager at Envision Energy. So, big thanks to all the people that worked very long hours at IWES to make this campaign a success!
After a final pit-stop at UTwente and in Bremerhaven for finishing assembly, the EcoSwing generator is ready for turbine integration. The project partners are now looking forward to the field campaign with a 3.6 MW test turbine from Envision in Denmark. The generator with a diameter of just 4 m will be transported there by ship.
EcoSwing at the 9th Meeting Session of the Association of German Engineers (VDI)
Written on .
Bremen, June 12-13, 2018 - Verein Deutscher Ingenieure (VDI) (English: Association of German Engineers) is an organization with over 150,000 engineers and natural scientists. Established in 1856, the VDI is today the largest engineering association in Western Europe. The association promotes the advancement of technology and represents the interests of engineers and of engineering businesses in Germany.
Certainly, the VDI takes an active role in the wind industry. In a two-days session from June 12 to June 13 three conferences take place under one roof. They will be covering mostly mechanical aspects from blades, over oscillations,to tower and foundations. Since the lowered top-head-mass enabled by superconductors has important benefits in this area, the EcoSwing has been invited to present on status and advancements.
Dr. Jürgen Kellers, ECO 5 GmbH, Bonn, and Dipl.-Ing. Hans Kyling,Fraunhofer IWES, Bremerhaven will deliver a plenary talk on Superconductors as a Cost Cutting Measure for Wind Turbines.
In a nutshell:
German Title: 9. VDI-Fachtagung Schwingungen von Windenergieanlagen
