Fewer components, increased profitability Siemens 3.0 MW direct drive wind turbines www.siemens.com/wind Answers for energy.

Outstanding performance with ­ 50 percent fewer parts 2

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. Siemens 3.0 MW direct drive wind turbines offer innovation through the consistent implementation of a highly efficient generator concept. With half the parts of con­ ventional geared turbines and much less than half the number of moving parts, the direct drive wind turbines are easy to maintain and extremely reliable....

“ ewer components, increased F p ­ rofitability! What once was only a dream is now ready for serial p ­ roduction. Comprehensive testing has shown that our direct drive wind turbines are 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 3.0 MW direct drive wind turbines, Siemens started with the ambitious aim of reducing the number of components...

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 3.0 MW direct drive wind turbines have a dual cooling system that provides an even cooling of the generator. The coolant life expectancy is...

The compact system design with a reduced number of rotating wear parts makes 3.0 MW direct drive turbines ideally suited for virtually any field of application. Expertise in practice: 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. Efficient lightning protection The 3.0 MW turbine has efficient lightning protection. Its overall basic construction is based on the international standard IEC 61400-24 Lightning Protection Level...
