Bibliography

Covers with mechanical load measurements on wind turbines. It mainly focuses on large (>40 m[2]) electricity generating horizontal axis wind turbines. Also describes the methodology and corresponding techniques for the experimental determination of the mechanical loading on wind turbines.

Acts as a guide for carrying out measurements used for verification of codes and for direct determination of the structural loading. Focuses mainly on large electricity generating horizontal axis wind turbines.

This publication is of high relevance for Smart Grid.
