Siemens Energy uprates its D3 onshore platform wind turbines



March 11, 2014 – Siemens Energy says it has uprated its D3 onshore platform wind turbines: the new SWT-3.2-101, SWT-3.2-108 and SWT-3.2-113 machines promise improved performance from 3MW to 3.2MW, and will enter serial production by the end of this year.

They will be available with 101-m and 108-m rotors for IEC class IA sites, and a 113-m rotor for IEC class IIA sites. The 3MW version will remain available for project sites with lower wind speeds. 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, says the company.
