During the design of wind turbines the load assumptions will be checked by computer simulation and proofed by a certification body.
The real proof is during operation of wind turbines. So a load comparison between measurements and simulations is required for a WT01-certificate.
Our service for load comparison of wind turbine loads:
Using the knowledge of the real characteristics of the wind turbine the potential for optimisation can be checked.
