Outstanding efficiency Siemens Wind Turbine SWT-2.3-93 Answers for energy. SIEMENS

Outstanding efficiency The SWT-2.3-93 wind turbine is the highestproductivity member of our 2.3 MW turbine family. Based on more than 25 years of leadingedge design and construction, it is suitable for almost any type of application, both onshore and offshore. A rugged, conservative structural design, automatic lubrication systems with ample supplies, climate control of the internal environment and a simple generator system without slip rings provide exceptional reliability at long service intervals. Power conversion is implemented with Siemens’ unique NetConverter® system, offering maximum flexibility...

Technical description General design Rotor hub The SWT-2.3-93 wind turbine is an upgraded version of the classical SWT-2.382 machine and includes the new B45 blade, a rotor diameter of 93 m, and hence a 25 percent increase of the swept area relative to the SWT-2.3-82 wind turbine. The rotor hub is cast in nodular cast iron and is fitted to the main shaft with a flange connection. The hub is large enough to provide a comfortable working environment inside the structure for two service technicians during maintenance of bolt connections and pitch bearings. Rotor Blade pitch system The SWT-2.3-93...

The yaw gear motors are fitted with brakes, assisting the passive friction of the bearing for stable maintenance of the yaw position. Controller A standard industrial computer is the basis of the turbine controller. The controller is self-diagnosing and includes a keyboard and display for easy status readout and adjustment of settings. Power conversion The NetConverter® power conversion system allows generator operation at variable speed, frequency and voltage while supplying power at constant frequency and voltage to the MV transformer. The power conversion system is a modular arrangement for...
