Siemens Energy has opened two major R&D test facilities for wind turbine technology in Denmark. The new test centre in Brande features test stands for major components of Siemens wind turbines, including generators, main bearings and complete nacelles. In Aalborg, seven blade test stands are capable of performing full-scale tests of rotor blades. Together, the two facilities form the world's largest R&D test centre for wind turbine technology, says the company.
"Our investments in testing today will result in savings for our customers tomorrow," said Felix Ferlemann, CEO of the Siemens Wind Power Division in Siemens Energy. "With our extensive tests of all major components of a wind turbine, we can significantly reduce the risk of technical issues in the field."
The two test centres feature indoor testing facilities of more than 27,000 m2. The nacelle test stands in Brande are capable of testing Siemens' D6 direct drive platform, the company's largest current wind turbines with a 6MW rated capacity, and are prepared to test even larger turbines.
The seven blade test stands in Aalborg and three blade tests stands in Brande together form the largest blade test facility in the world both in size and in scope, boasts Siemens. The Aalborg facilities are not only able to fully test Siemens' 75-m long B75 blade, but even larger blades. Wind turbine blades are now bigger than any other composite structure in the world, says Siemens, adding that the wing of an Airbus 380 is less than half as long as the B75 blade.
In its new test facilities, Siemens can perform HALT (highly accelerated lifetime tests) on all major components of its direct drive and geared wind turbine platforms. This year, 2013, also marks the 25th anniversary of Siemens' Wind Power's Test and Measurement Department.
