Siemens has introduced a generator upgrade to seven megawatt. The new Siemens SWT-7.0-154 delivers nearly ten per cent more energy production than the predecessor under offshore wind conditions while retaining the same proven reliability.
Development engineers have refined solely those turbine components needed to increase electrical output. The new model is already set to go into series production by 2017. Stronger permanent magnets and generator segments in the permanent magnet generator provide the key to harvesting a higher yield. Additionally, the converter and transformer have been upgraded, in line with the higher electrical output. All other components remain the same of the 6MW wind turbine. The 6MW-version will continue to be available for sales but following the improvements, Siemens has renamed the product platform to D7.
