PowerWind has commissioned its first 2.5 MW wind turbine

The prototype of PowerWind 90 was installed early December 2010 - A product version with a rotor diameter of 100 m is in preparation

Hamburg, 12 January 2011 - The German manufacturer PowerWind GmbH has successfully completed the commissioning of its first 2.5 MW wind turbine of the type PowerWind 90. The prototype with a rotor diameter of 90 meters was installed in Bremerhaven early December. On December 21, PowerWind 90 has
fed in power to the local electrical grid for the first time. At the beginning of 2011, the turbine will be handed over turnkey ready to the customer wpd AG. Thus, after a development period of less than three years, PowerWind will now have on offer, apart from the PowerWind 56 with 900 kW rated power already established on the market, also a turbine in the multi-megawatt range.

"The most important innovation of PowerWind 90 is its gearbox protection concept", says Thomas Korzeniewski, Head of the Research and Development Division of PowerWind."Two main bearings,a deformation-resistant main frame and two hydraulic gearbox supports ensure optimum transmission of the torque and keep unwanted loads away from the gearbox. Moreover, the gearbox is decoupled from the electrical grid by means of two full scale converters and protected from exposure to loads, which may occur, for example, during voltage drops. We are convinced that this will allow us to significantly increase the lifetime of the gearbox."

Due to the full-scale converters and an intelligent control system, PowerWind 90, with its excellent fault ride-through capabilities and extended reactive power control range, will meet even the most demanding grid requirements. From 2011, an additional product version of the 2.5 MW wind turbine with a rotor diameter of 100 m will be available for moderate wind sites, which will also meet German SDL requirements.
