| Sumario: | <p>The energy transition means that more and more wind farms are being built in
favorable offshore sites like the North Sea. The wind farms affect each other
as they interact with the boundary layer flow. This phenomenon is a topic of
current research by the industry and academia as it can have significant
technical and financial impacts. In the present study, we use data from the
Alpha Ventus wind farm site to investigate the effects of inter-farm
interactions. Alpha Ventus is the first offshore German wind farm located in
the North Sea with a fully equipped measurement platform, FINO1, in the near
vicinity. We look at the effects on the wind conditions measured at FINO1
before and after the beginning of operation of the neighboring farms. We show
how measured quantities like turbulence intensity, wind speed distributions,
and wind shear are evolving from the period when the park was operating alone
in the area to the period when farms were built and operate in close
proximity (1.4–15 <span class="inline-formula">km</span>). Moreover, we show how the wind turbine's
response in terms of loads and generator and pitch activity is affected using
data from a turbine that is in the vicinity of the mast. The results show the
wake effects in the directions influenced by the wind farms according to their
distance with increased turbulence intensity, reduced wind speeds, and
increased structural loading.</p> |
