High capacity wind turbine

The SWT-2.3-120 incorporates a variety of innovative technologies that have been scaled and streamlined to deliver a capacity factor for sites with medium to low average wind speeds. Together, these refinements have produced a turbine that is even more efficient under these wind conditions than its predecessor. The SWT-2.3-120 wind turbine employs a high-performance 120-meter rotor with 59-meter aeroelastically tailored blades allowing for enhanced energy capture. With a 23% increase in swept area and projected AEP over 9% higher than that of its predecessor for sites with average wind speeds around 7.5 meters per second, the SWT-2.3-120 is designed to help get the most out of medium to low wind sites. The nacelle is ergonomically optimized for maintenance through increased accessibility of components, and enclosed by a square steel canopy designed for maximum protection of internals. 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 easy maintenance and is water-cooled. Via a standard Web browser, the Siemens WebWPS SCADA system provides a variety of status views of electrical, mechanical, meteorological, and grid station data as well as operation and fault status.
