Siemens has introduced the new Siemens SWT-7.0-154, a generator upgrade to seven megawatt (MW) which delivers nearly ten percent more energy production than the predecessor under offshore wind conditions.
Stronger permanent magnets and generator segments in the permanent magnet generator provide higher yield. Additionally, the converter and transformer have been upgraded, in line with the higher electrical output. All other components remain the same as the 6MW wind turbine, SWT-6.0-154. The 6MW version will continue to be available for sale but following the improvements, Siemens has renamed the product platform to D7.
The SWT-7.0-154 will be presented at the international wind power conference and exhibition EWEA Offshore 2015 in Copenhagen, and is set to go into series production by 2017.
