【 摘 要 】

We address the issue of wake effects between two neighbouring offshore wind farms by analysing simultaneous production data from Rodsand II and Nysted. The upstream wind farm is found to not just perturb the flow in its wake, but also to cause speed-ups at the positions of some downstream turbines. We use the data to perform a validation of a simple wake model for flow cases corresponding to wind directions of maximum internal and external wake effects.
