Wind Turbines address low/medium wind and low noise site needs.

Press Release Summary:

Onshore direct drive wind turbines include models SWT-3.15-142, SWT-3.6-130, and SWT-3.3-130LN, which are respectively optimized for low-wind, medium-wind, and noise-sensitive sites. While all 3 machines share same nacelle design due to shared modular platform concept, different controller settings and rotor diameters allow turbines to adapt to specific wind and site conditions. Based on direct drive technology, SWT-3.3-130LN can operate with 104.9 db noise level at wind speed of 6 m/s.

Siemens Launches Three New Wind Turbines Based on One Onshore Direct Drive Platform

• Extended portfolio for low wind, medium wind, and noise sensitive sites
• Short time-to-market

Siemens has launched an extended portfolio of its successful Onshore direct drive wind turbines. At the WindEnergy Hamburg trade show, the company’s Onshore CEO Thomas Richterich launched three new turbine models for optimum performance at low wind, medium wind, and noise sensitive sites. Thanks to a modular platform concept, all three machines share the same nacelle design.

Different controller settings and rotor diameters allow the new turbines to adapt to specific wind and site conditions. As the second generation of onshore direct drive technology was introduced two years ago with the Siemens SWT-3.3-130, all new models benefit from a short time-to-market. The new low noise turbine – the SWT-3.3-130LN – and the new medium wind speed turbine – the SWT-3.6-130 - will go into serial production in early 2017. The low wind speed turbine - the SWT-3.15-142 - will follow in late 2017.

“Our new wind turbine portfolio is the result of an intelligent platform strategy that allows maximum flexibility,” said Thomas Richterich, CEO Onshore of the Siemens Wind Power and Renewables Division. “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.”

The SWT-3.3-130LN wind turbine is a low noise version of the SWT-3.3-130 with reduced rotor speed and improved aerodynamics. It is based on proven Siemens direct drive technology, and allows operation with a 104.9 db noise level at a wind speed of 6 m/s. The B63 blades of the SWT-3.3-130LN include new aerodynamic add-ons for optimized performance. In addition to the vortex generators applied on the blade backs, the trailing edges are equipped with Siemens DinoTails Next Generation.

Thanks to an uprated generator, the new SWT-3.6-130 is able to harvest an annual energy output (AEP) of up to 17 gigawatt hours (GWh) at 8.5 m/s. At the same wind speeds compared to the SWT-3.3-130 launched in 2014, this represents an improved AEP rating of 6 percent. With its high performance at IEC II sites, the SWT-3.6-130 sets a competitive benchmark for wind turbines designed to harvest maximum power outputs in environments with moderate wind conditions.

The new SWT-3.15-142 is the first Siemens Direct-Drive wind turbine dedicated for IEC Class III. It’s B69 rotor-blades are based on hybrid-carbon technology by LM Wind Power. With a rotor-diameter of 142 meters and tower configurations that allow hub heights up to 165 meters, new standards for annual energy yields are set:
Even at wind speeds of only six meters per second, the machine harvests ten gigawatt hours of energy per year.
