Built on experience Siemens Wind Turbine SWT-2.3-82 VS

The SWT-2.3-82 VS turbine is the classical workhorse for utility-scale wind turbine projects. It is the result of our unique experience from more than 25 years of leading-edge design and construction of wind turbines and represents the best of the qualities for which we are known throughout the wind industry. It is an efficient and reliable machine combining a solid and conservative design approach with high-performance technical features, such as the unique NetConverter® system with variable speed concept and the IntegralBlade® technology. The SWT-2.3-82 VS wind turbine is suited for tough and...

Technical description General design The SWT-2-3-82 VS wind turbine is a high-wind (IEC Class IA) version of the classical SWT-2.3-93 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. The gearbox is a custom-built, threestage planetary-helical design. The planetary-helical, high-torque stage provides a compact high-performance construction. The intermediary...

Turbine Condition Monitoring The yaw bearing is an externally geared ring with a friction bearing. Eight electric planetary gear motors drive the yawing. The yaw gear motors are fitted with brakes, assisting the passive friction of the bearing for stable maintenance of the yaw position. The wind turbine operates automatically, self-starting when the wind reaches an average speed of about 3–5 m/s. During operation below rated power, the pitch angle and rotor speed are continuously adjusted to maximize the aerodynamic efficiency. Rated power is reached at a wind speed of about 13–14 m/s, and at...
