Resumé

This investigation is part of the EU FP7 project “Distributed
Control of Large-Scale Offshore Wind Farms”. The overall
goal in this project is to develop wind farm controllers giving
power set points to individual turbines in the farm in order to
minimise mechanical loads and optimise power. One control
configuration examined is distributed control where turbines
only communicate with their nearest upwind neighbors. Design
of such controllers needs wake models and these models
should ideally be distributed. This paper compares two simple
multiple wake models for this purpose. The study is based
on real full scale data. The modelling is based on so called
effective wind speed. It is shown that there is a wake for a
wind direction range of up to 20 degrees. Further, when accounting
for the wind direction it is shown that the two model
structures considered can both fit the experimental data. However,
both models estimate a weaker wake than suggested by
the well known Jensen model.
