An innovative giant is tested


Prototypes are built to thoroughly test newly developed systems and/or their components and prevent possible operational problems as far as is possible. Since the end of April, measuring campaigns on an innovative electromechanical drive train have been performed on the CWD's 4-MW system test bench. The drive train is the central element of a 3-MW offshore turbine prototype developed by aerodyn engineering from Büdelsdorf, Germany for use on a floating offshore foundation. It is expected to soon go into operation off the south coast of Japan.

The load tests conducted include the application of six-dimensional wind loads to the rotor flange as well as dynamic grid events. This setup provided reproducible operating conditions for comparing crucial system parameters. Data was retrieved from over 180 measurement points. The acquired data describes the behaviour of mechanical and electrical systems and interactions between installed components at relevant operating points. Using the knowledge gained, the innovative turbine should be able to achieve automatic operation after only a comparatively short operating period at its final destination on the floating foundation. Testing on the system test bench ultimately reduces the number of unexpected failures, which are extremely costly especially for offshore sites. These findings are furthermore integrated into the development of subsequent turbine generations.

Delivery of the 90-tonne nacelle by heavy transporter was a first, even for the CWD, which is used to dealing with enormous machines. Previously inspected test objects were delivered in parts and assembled on site. Everything went to plan thanks to the 18-metre-wide hall door and 120-tonne gantry crane. The FVA Nacelle was dismantled and the new test object successfully installed in just ten working days. The test period was also completed successfully. However, the system test bench has no time to rest. The next test object is already lined up.
