Siemens’ new direct-drive low wind turbine has reached the prototype testing stage.
The onshore model SWT-3.15-142, with a rotor diameter of 142 metres, has successfully passed prototype approval and has now been erected at the Drantum wind test site in Jutland, Denmark.
The IEC Class IIIA wind turbine is the first Siemens model to be equipped with rotor blades based on hybrid-carbon technology.
Morten Pilgaard Rasmussen, head of technology at Siemens Wind Power, said: “With LM’s hybrid-carbon blades and our successful direct drive technology, this model incorporates proven and highly efficient technology in all components and we are confident that we can maintain short time to market and have this product ready for serial production by the end of 2017.”
Installation of the SWT-3.15-142 was completed with the rotor lift last week and the turbine is expected to be fully operational by the end of March. The focus of the testing program of the prototype is on blade and performance evaluation.
