Siemens D3 platform – 3.0-MW direct drive wind turbines Reduced complexity, increased profitability Answers for energy.

Your trusted partner 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. The combination of robust and reliable turbines, highly efficient solutions for power transmission and distribution, and a deep understanding of the entire energy market ensures that Siemens will continue to take the wind power industry to new levels. When it comes to on-time delivery, Siemens’...

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 core levers to this. And our new platform strategy, founded on the knowledge and experience of more than 30 years in wind power, is a milestone on this path. Standardization and modularization are fundamental to the new platform approach – allowing us to streamline the...

Performance and profitability go hand in hand With its direct drive wind turbines, Siemens started with the ambitious aim of making a more cost-effective machine in order to become competitive with conventional power plants. Thanks to innovative engineering, that vision is becoming a reality. In designing a wind turbine, a holistic view of the design and construction, materials, processes, manufacture, and installation is critical. The gearless 3.0-MW wind turbines carefully balance all these factors in a compact system. Service personnel have been involved in the development process in order...

Simplified design Due to the removal of the gearbox and other design simplifications, Siemens has given service technicians more space within the nacelle. Here, key components are readily accessible and can be interchanged without impacting others. The wind turbines of the D3 platform have a dual cooling system that provides an even cooling of the generator via a top-mounted, passive cooling system for improved energy efficiency. The key components in a wind turbine – the blade, rotor hub, tower, and controller – are all adopted from the existing Siemens geared turbine portfolio. The utilization...

Expertise in practice: fully developed technology, advanced design Grid performance with 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 NetConverter® system offers maximum flexibility in the turbine’s response to voltage and frequency control, fault ride-through and output adjustment. As a result, Siemens wind turbines can be configured...
