Direct-Drive Wind-Turbine Innovations

Electronics Hard- and Software, Tower, Nacelle, Hub, Generator

Frequency Converter, WT-control, Pitch-System.

A complete, state-of-the-art package has everything you need for high reliability and low cost.
- The AC pitch system can prevent extreme damage to the wind turbine.
- A decentralized control system via direct bus between all stations within the wind turbine offers maximum simplicity.
- An active front-end frequency converter has control circuits for power generation and also for harmonic suppression. The automatic bridging of a grid fault without switching off the wind-turbine must be manageable for several seconds.
