World's Largest Offshore Wind Farm Launches With 175 Siemens Wind Turbines

Today marks the inauguration of the world's largest offshore wind power plant, London Array. Siemens supplied the 175 wind turbines and the grid connection for London Array. Together with Dong Energy, Siemens will also be responsible for the service of the wind turbines through a long-term agreement. The wind power plant owned, developed and built by a consortium consisting of Dong Energy, E.ON and Masdar has a total capacity of 630 megawatts (MW) and will generate enough power to supply 500,000 British households with clean electricity. London Array will reduce annual CO2 emissions by approximately 900,000 tons, which equals the emissions of 300,000 passenger cars.

Semikron launch SKiiPX IGBT modules for wind turbines

Under harsh climatic conditions, secondary damage caused by moisture ranks among the most common causes of failure of power electronics modules. Therefore, a module specified to allow for condensation will offer a significantly increased lifetime. Semikron’s new SKiiPX IGBT module is designed for extreme climatic conditions and allows for condensation during operation. It meets the specific requirements for wind turbines in the 1-6MW power range.
