The testing, which is scheduled to be completed by the end of the year, is being carried out at the IWES Dynamic Nacelle Testing Laboratory (DyNaLab) in Bremerhaven, Germany.
During the trials, mechanical and electrical tests will be carried out on the integral chain of the drivetrain and main tower components by simulating operational conditions for extreme and fatigue loads.
The firm will assess individual and fully integrated subsystems as well as the complete drivetrain operation at full power.
Adwen chief technology officer Maite Basurto said: "This is an extremely important step forward in our comprehensive validation program.
"We have the opportunity to test core systems of the wind turbine in a world leading facility and this will contribute to certify the turbine faster and ensure it achieves the highest performance."
Adwen said that the tests are significant to reducethe field test campaign and speed-up the turbine certification.
Upon successful completion of the full drivetrain testing, a complete AD 8-180 nacelle will be installed on a prototype which is currently being assembled at Bremerhaven.
The prototype is planned to be installed in Bremerhaven by the end of this year following completion of final tests and checks.
