Wind Turbine Assessment Service
Mechanical Loads, Power Performance, Acoustic Noise / Vibration. When developing new wind turbines, extensive measurements of the mechanical loads acting on the prototypes during operation are indispensable. The results of these load measurements carried out by DEWI are used in the design validation and certification of wind turbine prototypes. Design validation and certification represent the key to a mechanically reliable wind turbine which is ready for series production.

Instead of IEC-type load measurement, DEWI also offers special on-line load monitoring of wind turbines and their components. As a cost-effective alternative to IEC-type load measurements this is particularly suitable for determining local strains or stresses in the material, and enables a direct comparison to be made between the site-related loads and the data simulated in the design development by extrapolating the measured data.
The measurement of wind turbine power curves is one of the key activities in the range of services of DEWI. Together with an assessment of the wind climate at the site, it forms the basis for an energy yield analysis. Wind turbine suppliers can use the results of power performance measurements to optimise their machines. The measurement data allow owners of wind turbines to check whether or not a turbine conforms to the specifications given by the supplier.
Noise emissions are an important limiting factor in the layout of a wind farm. Qualified noise predictions are therefore essential for the planning of a wind farm. DEWI has been carrying out noise measurements and noise immission predictions for many years in line with the relevant standards and guidelines and is also participating in national and international research projects for the noise reduction of wind turbines, sound propagation and the further development of measuring methods.
