SUPRAPOWER (SUPerconducting, Reliable, lightweight, And more POWERful offshore wind turbine) is an EU FP7 founded research project focused on a major innovation in offshore wind turbine technology by developing a new compact superconductor-based generator.
The project aims to provide an important breakthrough in offshore wind industrial solutions by designing an innovative, lightweight, robust and reliable 10 MW class offshore wind turbine based on a superconducting (SC) generator, taking into account all the essential aspects of electric conversion, integration and manufacturability.
The total budget of the project is EUR5.398.019,03, with EUR 3.891.058,45 being funded by the European Commission. The project has already started at the beginning of December 2012 and it is expected to be finished at the end of 2016.
Today’s geared as well as direct-drive permanent magnet generators are difficult to scale up further. Their huge size and weight drives up the cost of both fixed and floating foundations as well as O&M cost. New solutions to provide better power scalability, weight reduction and reliability are needed. Superconductivity may be the only technology able to combine such features and allow scaling to 10 MW and beyond by radical reduction of the head mass.
SUPRAPOWER will pursue:
After 4 years of own development and from an already patented concept as a consequence of that work, the coordinator (TECNALIA Research & Innovation) has assembled a top-class European consortium from 7 countries. Industrial partners are: a wind turbine manufacturer (ACCIONA WindPower), an energy company (ACCIONA Energia), an SME superconducting wire developer (COLUMBUS Superconductors), a cryogenic systems supplier (Oerlikon-Leybold Vacuum; OLV), and an offshore engineering company (D2M Engineering).
In addition to the coordinator, research partners are: an important laboratory with deep experience in superconductivity (Institute of Electrical Engineering Slovak Academic of Sciences; IEE), a university (University of Southampton) and a national institute (Karlsruher Institut Technologie; KIT).
The main outcome of the project will be a SC generator able to be scaled in wind turbines up to power levels of 10MW and beyond, enforcing a key European technology.
