  1. Siemens Launches New Onshore Direct-Drive Wind Turbines

    By Editors of Power Engineering Siemens  today announced the addition of three new wind turbines to its  onshore , direct-drive portfolio. Onshore CEO Thomas Richterich made the announcement at the WindEnergy trade show in Hamburg, Germany. The three new turbines are based on a modular platform and share a common nacelle design. Relying on different controller settings and rotor diameters, they are purpose-engineered for sites that experience low wind, medium wind, or noise constraints.  Siemens' low-wind-speed turbine (SWT-3.15-142) is the first Siemens direct-drive wind turbine dedicated to IEC Class III operation. Its B69 rotor blades are based on hybrid-carbon technology from LM Wind Power. Configured for hub heights of up to 165 meters, the new machines can harvest 10 gigawatt hours of energy per year at wind speeds of only 6 meters per second. The medium-wind-speed turbine (SWT-3.6-130) features an uprated generator and can harvest an annual energy output of up to 17 GWh at wind speeds of 8.5 m/s, which represents a 6 percent improvement in performance over previous technology iterations.  The low-noise turbine (SWT-3.3-130LN) is a reduced-noise version of Siemens’ SWT-3.3-130, with decreased rotor speed and improved aerodynamics. At wind speeds of 6 m/s, it allows for operation at 104.9 decibels. The B63 rotor blades used in the turbine incorporate new aerodynamic add-ons to optimize performance. These new models will benefit from a short time to market, since they build on the second generation of onshore, direct-drive wind turbines released two years ago. The low-noise and medium-wind-speed turbines will go into serial production beginning early 2017. The low-wind-speed turbine will follow in late 2017.  “Our new wind turbine portfolio is the result of an intelligent platform strategy that allows maximum flexibility,” said Richterich. “Our customers benefit not only from benchmark setting performance in different wind classes, but also from the adaptability of our technology that meets nearly every site-, grid- and project specific requirement. Thanks to digitalization, these turbines are open for further optimization and individualization.” Earlier this week Siemens also announced their second generation of  quieter rotor blades . These DinoTails Next Generation blades harness aeroacoustic technology observed in the silent flight of owls to reduce on-site noise at wind power installations.
