At the centre of its trade fair presentation, German FWT energy GmbH & Co. KG will be showcasing the 3 MW turbine generation designed by the consulting company W2E. The FWT 3000 is designed for high efficiency even at medium and low wind conditions inland, and also for optimised logistics as well as international grid compatibility. The turbine was designed to meet the requirements of IEC 61400-1, Wind Class 2a, so it has plenty of potential for a further performance increase. In the current design, the nominal power of 3 MW is available even at only 12 m/s wind speed. In addition to the 90 m and 100 m high steel tower version, the new octagonal Ventur hybrid tower (a combination of precast concrete sections and steel tubing) with a total of 140 m height will be deployed for the first time. The turbine is based on the drivetrain concept that was first implemented in the Fuhrländer FL 2500. In this compact drivetrain, the rotor is fixed directly to the machine carrier using a three-stage braking/torque bearing. The HybridDrive system from Winergy consists of a transmission unit with two planetary stages (the spur gear stage was no longer required) that increases the rotor rotational speeds from between 6.0 and 16.0 rpm up to a medium rotational speed of between 213 and 568 rpm for the permanently excited synchronous generator.

Siemens is focusing on consistency and the integration of components and systems, so it can offer a consistent protection concept, for example, that comprises many individual components. This reduces system downtime and increases availability. Siemens is offering platform concepts for manufacturing wind turbines that accelerate the construction process with the help of software tools and also reduce the number of system components. The Siemens range covers the entire life cycle of a wind turbine, from planning and engineering through manufacture right up to operation. The range includes technologies for automation, visualisation, Wind Edition 25
