Most powerful test bench in wind industry operational

Vestas (OMX: VWS) has activated what it refers to as the ‘most powerful test bench’ in the wind industry at its global testing centre in Aarhus, Denmark.
The 20 MW test bench is capable of testing the full nacelle of the V164-8.0 MW, validating the performance, robustness and reliability of the turbine over a simulated 25-year lifetime.

According to the Vestas website, the test bench is 42 meters long and 9 meters wide. The total weight of the test bench, including the motors, wind simulator and generators is nearly 700 tonnes. Vestas installed fifty meter deep concrete foundations to support the weight. Motors powering the bench produce 20 MW- the equivalent of 26,820 brake horsepower, and the torque exerted on the components of the turbine can be up to a massive 18 meganewton metres.

The enormous test bench will stress the drivetrain, including the gearbox, main shaft and generator of the V164-8.0 MW - in a controlled environment - reproducing the harsh wind conditions in the North Sea, using a comprehensive and rigorous test regime based on experience and data gathered from over 25,000 turbines.
