Wind Turbine Assembly-PW:56

Dated: 01/03/2016

The PowerWind 56 is a variable-speed, pitch-controlled wind turbine, certified in accordance with IEC wind class IIA and DIBt WZ III. It has a rated power output of 900 kW and a rotor with a diameter of 56 m. The design of the PowerWind 56 is based on the proven concept of the modular drive train. This concept has undergone advanced further development by applying the experience gained from large multi-megawatt turbines.

The design of the PowerWind 56 meets the specific requirements of the emerging wind markets. Suitable logistics make  the  PowerWind  56  particularly beneficial for locations that are difficult to access or have weak infrastructure.   The   advanced   cooling   concept   allows for smooth operation even under challenging climate conditions. The PowerWind 56 is equipped with a water- cooled  asynchronous generator  or  optional  with  an  air- cooled permanent magnet synchronous generator. Thanks to its full scale converter technology, the PowerWind 56 can be connected even to weak electrical grids.

The PowerWind 56 is modelled after the proven modular drive train concept.· High·reliability·due·to·the·combination·of·sophisticated·components·by·reputable·European·manufacturers
