Project objectives

For the design of larger and higher wind turbines, being able to consider realistic wind conditions, with the help of wind field models that are as precise as possible, is gaining importance, especially since these systems are increasingly influenced by the elastic behaviour of the large rotor. The existing wind field models are only partially able to do justice to this, due to the incomplete consideration of turbulent structures and extreme events. The joint project EMUwind aims to combine the expertise of the research partners in the fields of innovative wind measurements, wind modelling and load calculations in cooperation with industrial partners to derive improved wind field models and to characterise the uncertainties contained therein. For this purpose, extended wind field measurements will be carried out, and analysed together with existing measurement data regarding the new wind field properties and parameters.

 

Specific contributions and objectives WESys

In the joint project EMUwind, extensive wind field measurements are carried out with remote sensing technology, to create the database for the validation of load calculations on the one hand, and to develop suitable measurement strategies for the acquisition of special wind field properties on the other. The main goal of the participation of AG WE-Sys in the project is a SpinnerLidar measurement campaign for the measurement of the long-term wind field statistics with simultaneous high spatial and temporal resolution. Based on this measurement, the extraction of wind field parameters, advanced wind field reconstruction, and a characterisation of extreme operating gusts should be carried out. A total measurement duration of twelve months is aimed at, with measurements being carried out first for six months on the measurement mast of the research platform in Krummendeich and then for a further six months in the spinner of a wind turbine at the same location.
