Siemens D6 platform – 6.0-MW direct drive wind turbine

Siemens, the offshore leader Siemens has been a major driver of innovation in the wind power industry since 1980 when wind turbine technology was still in its infancy. Technology has changed with the times, but Siemens’ commitment to providing its customers with proven wind turbine solutions remains the same. In recent times, the world has seen an intense increase in the nature and capacity of offshore wind power plants. Given the logistical challenges of offshore projects where even the smallest issue can amplify costs, having technology that works and continues to work is paramount....

Intelligent ways to drive down the cost of electricity Wind power is coming of age. It could soon be directly competitive with traditional energy sources. Driving down the levelized cost of wind energy is a key target for Siemens as we strive to make wind power independent of subsidies. Innovation and industrialization are the main drivers of this. And our new platform strategy, founded on the knowledge and experience of more than 30 years in wind power, is a milestone along this path. Standardization and modularization are fundamental to the new platform approach – because they allow us to...

Lean, robust, and reliable technology Lean The Siemens 6.0-MW turbine of the D6 platform is based on proven Siemens direct drive technology: the simplest and most straightforward wind turbine design. Replacing the gearbox, the coupling, and the high-speed generator with a low-speed generator eliminates two-thirds of the conventional drivetrain arrangement. As a result, the number of rotating and wear-prone parts is vastly reduced, with 50 percent fewer parts than a comparable geared machine. The associated reduction in maintenance requirements is crucial in offshore applications. Until now,...

Benefiting from our unique offshore experience, the D6 platform is designed to exploit the broadest range of offshore environmental conditions. Designed to IEC I standards, the D6 platform can be deployed in any known offshore location. The Siemens D6 platform is designed to both maintain and enhance the legendary reliability of Siemens wind turbines. Simple and robust, the direct drive technology offers the best possible basis for this. The rotor blades combine lightness and strength through single-cast Siemens IntegralBlade® production. The structural capacity of all components is...

Proven technology, advanced performance Grid performance with the Siemens NetConverter® Turbine Load Control (TLC) Siemens sets the standard in the field of grid compliance. Power conversion is implemented by the Siemens’ NetConverter® system. This system is characterized by full conversion of the power generated, efficiently decoupling generator and turbine dynamics from the grid. The Turbine Load Control system continuously monitors the structural loading on the wind turbine. In case the loads exceed normal values, the turbine automatically regulates operation to bring loads back within...

Nominal power Rotor diameter Blade length Swept area Site specific Power regulation Pitch regulated, variable speed Tower head mass The 154-meter rotor, designed specifically for the Siemens D6 platform, uses the B75 blade. This is currently the world’s longest blade in operation, with a swept rotor area of 18,600 square meters. It therefore maximizes energy yield at offshore locations: from inland waters with moderate wind resources to the most exposed offshore sites. Through optimized infrastructure, installation, and service, the D6 platform is the perfect choice for a reliable and...
