Abstract Wind farm control can play a key role in reducing the negative impact of wakes on wind turbine power production. The helix approach is recent innovation field control, which employs individual blade pitch to induce helical velocity profile wake. This forced meandering wake has turned out be very effective for recovery wake, increasing output downstream turbines by significant amount. paper presents tunnel study with two scaled models upstream operated approach. We used tomographic particle image velocimetry dynamic behavior under influence excitation. measured flow fields confirm capabilities compared normal operation. Additional emphasis put effect breakdown tip vortices, process that plays an important re‐energizing Measurements indicate vortices and resulting destabilization are enhanced significantly Finally, measurements show was able increase combined this particular two‐turbine setup as much 15%.
