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 3.2MW 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. The uprated Siemens D3 wind turbines represent a classical wind turbine evolution, combining a proven and tested concept with new 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 new platform delivers up to 4 per cent more energy yield annually.
