Up-rated turbine

Siemens Energy has up-rated 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 3.2 megawatts (MW), and implement the sum of design and operational experiences. The up-rated products 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. 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. Overall, the new product generation has resulted in delivering up to four percent more energy yield that its predecessor.
