At the leading edge of evolution
The 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
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 conditions than anyone thought possible.
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.
Based on innovative aerodynamic solutions in the root and tip sections, the Quantum Blade offers maximum efficiency at low to medium wind speeds.
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.
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.
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
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.
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.
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 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.
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.
The world‘s first offshore wind power plant was constructed 1.5 km off the Danish coast, near the port of Vindeby (windy city in Danish). To protect against corrosion, the turbines were built with airtight towers and nacelles, and are colled by heat exchangers.
Middelgrunden was established in the autumn
of 2000, on a natural reef with 3 to 8 meters water depth, 3.5 km outside
This offshore wind farm is the largest in the world based on cooperative ownership.
The Danish island of Samsø produces renewable energy far in excess of the local energy consumption. The key reason for that remarkable fact is the locally owned offshore wind farm installed by Siemens.
The wind farm itself is made up of
eight rows of nine turbines each. The 72 wind turbines annually generate
power to supply 145,000 homes with environmentally friendly energy.
