Bright outlook for improved profitability Direct drive wind turbine SWT-3.0-101 www.siemens.com/wind Answers for energy.

How can you gain maximum p ­ erformance with 50 percent fewer parts? 3

As wind power plants develop capacities similar to conventional power plants, power generation companies throughout the world are striving for greater efficiency and cost-effectiveness. Siemens’ solution: increase availability and profitability through innovative technology. The SWT-3.0-101 wind turbine from S ­ iemens 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...

“Fewer components, increased profitability! What once was only a dream is now ready for serial production. Comprehensive testing has shown that the new direct drive wind turbine is a reliable investment in the future of power generation.” Henrik Stiesdal, CTO, Siemens Wind Power Performance and profitability go hand in hand In designing a wind turbine, a holistic view of the design and construction, materials, processes, m ­ anufacture, 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....

Simplified design Despite the compact design, Siemens has actually given service technicians more space in which to operate. The drastic reduction of parts has created a relatively spacious environment within the nacelle, where key components are readily accessible. The “plug and play” nature of components allows most components to be interchanged without impacting other components. The top-mounted, passive cooling system improves energy efficiency. The SWT-3.0-101 has a dual cooling system that provides an even cooling of the generator. The coolant life expectancy is also increased, aiding both...

The compact system design, with a reduced number of rotating wear parts, is an ideal basis for profitable deployment onshore, offshore, and in coastal areas. A new definition of ­ ompetence: c fully developed technology, advanced design Grid performance with NetConverter® Grid stability requirements grow as more wind power is fed into the grid, and 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...
