At the leading edgeof evolutionThe new Siemens SWT-2.3-113 wind turbine is the ultimate choice for low to moderate wind conditions. The revolutionary direct drive generator and the new, optimized Quantum Blade are paired to extract as much energy as possible from the wind.
Efficient. Quiet. Robust and reliable. The Siemens SWT-2.3-113 is the new benchmark wind turbine for low to medium wind speeds. As a result of more than 30 years of research and development, it is designed to harvest more energy out of moderate wind con-ditions than anyone thought possible.
Proven design
The SWT-2.3-113 is built around the same revolutionizing direct drive generator as the SWT-3.0-101. The direct drive turbine offers exceptional reliability and efficiency – with only 50% of the parts normally required for a conventional wind turbine. By using the same proven design and sharing the majority of components with its larger sibling, production costs and lead times can be kept down.
Unique aerodynamics
The Quantum Blade combines excep-tional aerodynamic performance with patented manufacturing technology. Based on innovative aerodynamic solutions in the root and tip sections, the Quantum Blade offers maximum efficiency at low to medium wind speeds.
Maximum availability
Simplicity is the ultimate sophistication. With the simple and robust direct drive concept with 50% fewer parts, the SWT-2.3-113 wind turbine is designed for maximum availability. Furthermore, the spacious nacelle and the ergonomic working conditions facilitate service-ability and contribute to minimizing downtime for scheduled maintenance.
At the leading edgeof evolution
You cannot change the wind. It may be strong, it may be light. This leaves it up to us to extract as much energy as we can from it.
Anne Schannong Vinther, Quality Engineer
Innovation for efficiencySiemens direct drive technology and the new Quantum Blade represent groundbreaking wind turbine design and technology. The result of these two key innovations is a turbine with maximum efficiency and reliability, which helps to enable a solid return on investment.
Maximized performance with 50% fewer parts
The Siemens direct drive design incorporates a permanent magnet generator with fewer moving parts than ever before.
The simple permanent magnet design offers increased efficiency directly by minimizing energy losses and indirectly by reducing maintenance needs. The outer rotor arrangement leads to a more compact and light-weight generator, making transport-ation and installation easier and faster.
The B55 Quantum Blade
The new generation of Siemens wind turbine blades is lighter than previous designs but retains the superior
strength known from earlier genera-tions of blades. Thanks to unique airfoils and redesigned tip and root sections, the blade offers superior performance at low to medium wind speeds. The root section uses Siemens “flatback” profiles to minimize root leakage and provide higher lift. The tip has also undergone a fine-tuning process to give enhanced lift and acoustic performance.
One-piece moulding
Like other Siemens blades, the new Quantum Blades are manufactured in Siemens proprietary IntegralBlade® process. Each blade is moulded in one single production step from fiberglass-reinforced epoxy resin, resulting in a stronger, lighter blade without any joints.
Lower noise
With a low 105 dB noise level, the SWT-2.3-113 is one of the quietest wind turbines on the market. As a result, this turbine type has an extremely high ratio of energy out-put per noise affected area, resulting in fewer disturbances to people and wildlife.
Superior grid compliance
The Siemens NetConverter® is designed for maximum flexibility in the turbine’s response to voltage and frequency variations, fault ride-through capability and output adjustment. The advanced wind farm control system provides state-of-the-art fleet management.
