Adwen has begun testing the drive train of the AD 8-180 at the IWES Dynamic Nacelle Testing Laboratory (DYNALAB) in Bremerhaven. The validation process will continue until the end of the year and includes mechanical and electrical tests of the drive train and the primary tower components as a unit.

Scientists perform extreme load and fatigue load tests at the laboratory, which opened in October 2015. The laboratory simulates real-world operating conditions for the validation process. The testing procedure permits the validation of parts of systems both standalone and fully integrated. The complete drive train can be validated under full load. The manufacturer's aim with the simulations is to reduce the duration of field-testing to accelerate the certification process.

The preparation work on the test rig started towards the end of last year. The drive train was transported to DyNaLab in April 2016, where mechanical assembly followed, along with the installation of additional fittings for sensors and the lubrication system. More than 350 sensors on the drive train gather important data during the tests. In a further step, the entire nacelle of the AD 8-180 will be brought to the IWES DyNaLab to undergo final testing. Installation of a prototype with this nacelle is scheduled for the end of the year in Bremerhaven.

"It is an extremely important step forward in our comprehensive validation programme. It gives us the opportunity to test the essential core components of our wind turbine in the world's leading testing facility. It will also help us to get this turbine certified more quickly and ensure that it has an optimum performance“, said Maite Basurto, Adwen Chief Technology Officer (CTO).
