Siemens Wind Turbine SWT-3.6-107 New dimensions Nominal power: 3600 kW Rotor diameter: 107 m Swept area: 9000 m2 Tower: 80 m or site-specific Rotor speed: 5-13 rpm Operational data: Cut-in wind speed: 3-5 m/s Nominal wind speed: 13-14 m/s Cut-out wind speed: 25 m/s Generator: Asynchronous Gearbox: 3-stage planetary/helical Monitoring: SCADA system: WebWPS Remote control: Full turbine control The SWT-3.6-107 wind turbine is one of the largest models in the Siemens Wind Power product portfolio. It was specifically designed for offshore applications, but works equally well onshore. The 107-m rotor has a swept area of 9,000 square meters, and with the advanced aerodynamics of the B52 IntegralBlade® technology the energy yield sets new standards. The SWT-3.6-107 machine is ideal for offshore markets worldwide. A rugged, conservative structural design, automatic lubrication systems with ample supplies, climate control of the internal environment, and a simple generator system without slip rings provide exceptional reliability at long service intervals. Grid stability requirements grow as more wind power is fed into the grid and the SWT-3.6-107 machine also sets new standards here. Power conversion is implemented with Siemens’ unique NetConverter® system, ensuring compliance with all relevant grid codes and offering maximum flexibility in the turbine response to voltage and frequency control, fault ride through and output adjustment. Despite the new features, the classical advantages of the earlier Siemens turbine types have not been forgotten in the SWT-3.6-107 design: major components, such as the rotor hub, the main shaft, the gearbox and the yaw system are all of particularly heavy dimensions, the safety systems are fail-safe, the blade and nacelle lightning protection performance is well-proven, and all details are designed using best engineering practice. A solid Siemens basis improved with the latest performance standards – that’s the SWT-3.6-107 turbine.	Direct drive wind turbine SWT-3.0-101 Bright outlook for improved profitability more info link Nominal power: 3000 kW Rotor diameter: 101 m Swept area: 8000 m2 Rotor speed: rpm Power regulation: pitch regulated Gearbox: NO The SWT-3.0-101 wind turbine from Siemens offers innovation through a completely new generator. With half the parts of a conventional geared turbine, and much less than half the number of moving parts, the new wind turbine is easy to maintain and extremely reliable. The compact design allows for cost-effective transportation on standard vehicles within most markets. In designing a wind turbine, a holistic view of the design and construction, materials, processes, manufacture, and installation is critical. With the SWT-3.0-101, Siemens started with the ambitious aim of reducing the number of components by half, while increasing performance. Thanks to innovative engineering, that vision is now a reality. The gearless SWT-3.0-101 carefully balances all these factors in a compact system that has the potential to significantly lower maintenance costs and service time. Reduced complexity Regardless of how reliable Siemens’ wind turbine gearboxes have been in the past, the gearbox is always the most complex component of a wind turbine. Eliminating the gearbox reduces complexity and increases reliability. Siemens has opted for a permanent magnet generator for improved efficiency. Unlike an electrically excited machine with a gearbox, a permanent magnet excited machine does not expend any energy on the excitation itself. The SWT-3.0-101 also has an outer rotor, where the rotor spins on the outside of the stator. This design feature allows the rotor to operate within narrower tolerances, which aids in keeping the dimensions of the nacelle compact.

Siemens Wind Turbine SWT-3.6-120 Thoroughly tested, utterly reliable Nominal power: 3600 kW Rotor diameter: 120 m Swept area: 11300 m2 Tower: 90 m or site-specific Rotor speed: 5-13 rpm Power regulation: Operational data: Cut-in wind speed: 3-5 m/s Nominal wind speed: 12-13 m/s Cut-out wind speed: 25 m/s Generator: Asynchronous Gearbox: 3-stage planetary/helical With the release of a new 3.6-megawatt wind turbine featuring a 120-meter rotor, Siemens has produced a machine that can generate more power than its predecessor could at similar wind speeds. The SWT-3.6-120 is based on the proven technology of the SWT-3.6-107, which is currently the world’s most popular offshore wind turbine. Basically, the only difference between the two machines’ core components is the rotor. The SWT-3.6-120 is equipped with 58.5-meter long rotor blades, giving it a swept area of 11,300 m2 or the equivalent to nearly two football fields. Tests indicate that the new machine will generate approximately 10 percent more electricity in comparison to similar wind turbines.	The new Siemens 6.0 MW Nominal power: 6000 kW Rotor diameter: 120 m or 154m Swept area: 11300 m2 or 18600 m2 The Siemens 6.0 MW offshore wind turbine redefines the wind industry standards for leanness, robustness and lifecycle profitability. Based on Siemens Direct Drive technology, the 6.0 MW turbine has 50% fewer moving parts than comparable geared machines and a towerhead mass of less than 350 tons. This unique combination of robustness and low weight significantly reduces infrastructure, installation and servicing costs, and boosts lifetime energy output. Incorporating the aggregate intelligence of Siemens, the 6.0 MW offshore wind turbine thinks for itself. It constantly manages its own operating load helping it remain within its design criteria irrespective of the conditions. Its advanced diagnostics system provides comprehensive real-time performance data and service requirements and will keep track of lifetime use and its overall asset condition. Even its user interface is clear and intuitive. It is no coincidence that a product of this simple beauty and intelligence has been created by Siemens. We are world leaders in offshore wind power, with over 20 years of experience.

Offshore wind power When it comes to offshore wind power, no supplier can match Siemens in experience and stability. Siemens has a proven and unique offshore track record, ranging from the world’s first offshore wind farm almost 20 yeas ago to today’s largest offshore projects. All projects have been delivered on time and on budget, and have recorded high availability. Optimized processes across the complete project lifecycle make Siemens a stable, reliable and trustworthy business partner. Siemens has not only supplied the world’s first, but also the world’s largest offshore projects. The 165-MW Nysted offshore wind farm has held the record as the largest offshore project for several years now. This record is expected to be broken when the 200-MW Horns Rev II project is commissioned. The 500-MW Greater Gabbard project, currently in progress in the UK, would raise the bar again. And the world’s first 1-GW wind turbine project, London Array, would represent yet another stride towards large-scale green energy supply. All record projects – and all featuring Siemens wind turbines.
