Measurement Campaign of a Large Rotor Wind Turbine

This work reviews some of the main tools used for designing a measurement campaign on a multi megawatt scale wind turbine. The aim of the measurements is to contribute to the qualification of new large turbine technology, assess the fatigue life of wind turbine components, as well as to validate simulation tools. Due to the size of the wind turbine structure, there are potentially new dynamic properties and identifying these will reduce the design- and operational risks. The complexity of measuring the dynamic properties of a large wind turbine is addressed and some of the main theoretical methods are outlined. In addition possible measurement equipment has been reviewed.
