                Superior design for superior performance

                When winds are strong, but site conditions less complicated, you need a turbine that will bridge these factors. Presenting Siemens’ SWT-3.2-108 and SWT-3.4-108 direct drive onshore turbines, a superior combination of large rotor and robust design.

                The B53 quantum blade of the 108-meter rotor was the first full-scale application of Siemens’ innovative aeroelastic blade design, which allows for a larger rotor diameter and higher energy output without increasing structural loads. Even more, the rotor’s weight did not increase in comparison to the B49 blade. As a result, the SWT-3.2-108 and SWT-3.4-108 turbine provides lower cost of energy at moderate to high wind conditions.

              • Onshore Direct Drive Wind Turbine SWT-3.2-113

                Annual output at 8.5 m/s: 12.2 GWh (3.2 MW)

                Simplifying profitability

                The SWT-3.2-113 was created so that you get the most out of your unique onshore sites, with features that maximize returns without compromise. Based on the proven, simple, and highly efficient direct drive technology it delivers high value while minimizing the cost of energy.

                Innovative design for performance optimization

                The competitive edge of the SWT-3.2-113 turbine comes from its innovative blade design. The B55 is the first one made using the Quantum Blade technology and applies new airfoils and redesigned tip and root sections, resulting in minimized loads and maximum energy output for this size of turbine. Furthermore, due to a lower but variable rotor speed, the SWT-3.2-113 has reduced noise emission.

                Tower heights between 83.5 and 115 m take you and your investment higher than predecessor models could. To get the most out of moderate wind conditions, the SWT-3.2-113 can be equipped with additional features – like the High Wind Ride-Through functionality to avoid abrupt shutdowns at higher wind speeds, or the power boost function, which can increase the turbine’s annual output by up to 4%.

                The combination of high energy output and low noise levels makes the direct drive SWT-3.2-113 turbine the ideal choice for most inland sites across the globe.

                Evolved technology for optimal benefits

                Evolution is the key to successful, efficient wind power plants. To ensure that you receive a lifetime of maximum returns from your onshore wind farms, we developed the SWT-3.3-130 by extracting the best from proven, reliable technologies, and building on them.

                Innovative design for onshore optimization

                A major part of the secret to this turbine’s success is the use of scaled components. Whether it’s the longer generator due to an extra row of magnets ensuring increased performance, or the updated nacelle design which accommodates an even more efficient direct cooling system: based on best practices small innovations help deliver reliable and efficient solutions. The longer B63 blade, compared to the predecessor SWT-3.2-113, are possible because of the benefits of the Aeroelastically Tailored Blade design. This allows a larger rotor while staying within the design load envelope and so provides a cost-optimized blade design with optimized energy yield. For increased performance and reduced noise, the blades use Vortex generators on the entire length and have Dino Tails attached on their trailing edges.
                In addition to high yield at moderate wind conditions, the SWT-3.3-130 employs other important elements for your onshore site. A variety of tower heights (85, 115 and 135 meters) enable tip heights up to 200 meters, making the SWT-3.3-130 the ideal choice for most onshore sites.

                    Confident in every part’s strength

                    In our ongoing effort to ensure that innovation addresses your needs, any opportunity for improvement that Siemen’s isolates is explored for its maximum benefit. The SWT-7.0-154 is one example of this. Designed to IEC 1B standards, it can be deployed even in challenging offshore conditions. The 154 m rotor features the Siemens B75 blade, which enables a swept rotor area of 18,600 m2. Despite being one of the lightest blades in its class it still maintains the strength needed for a 25-year design lifetime.

                    Our Offshore Direct Drive wind turbines feature a proven and reliable technology with a long-term track record. Over 1,300 of these gearless wind turbines have been installed since 2010, and almost 200 of them are in operation offshore. So reusing the direct drive technology and learning from the SWT-6.0-154 reduced the lead time for type certification of the SWT-7.0-154. The result: through upgrades in the nacelle, this premium offshore turbine provides 10% more energy than its predecessor.

                    Whereas the generator's permanent magnets and segments as well as the transformer upgrades are required solely for the higher output requirement, the upgraded Siemens Integrated Control System (SICS) with enhanced power converter provides even more flexibility in the turbine response to voltage and frequency, while enabling compliance with the strictest international grid code requirements. Obtaining type certification in 2016 marked the final milestone in the development process, allowing you to make final investment decisions for offshore projects and lower the risk of this investment.
