Description:Wind turbines are typically placed in regularly spaced arrays. One major issue for arrays is wake loss, which causes the overall power output of a wind farm to drop. One potential solution to this problem is known as wake steering. Wake steering yaws some turbines with the intention of deflecting the wake away from downstream turbines, thereby decreasing the power in the upstream turbines in an array which lowers the power output of a few turbines to increase the power output of the wind farm overall. Preliminary analysis with a 1 meter HAWT scale wind turbine is performed with the intention for further analysis and experimentation. Setting up the turbine required a new understanding of DAQ board wiring and LabView setup and analysis, as well as instrumentation set up. A theoretical power curve is constructed using Qblade, and the turbulent-boundary-layer spire requirements for the UNH FPF are calculated. The hope for this project is full preparation for atmospheric boundary layer simulation and wind turbine experiments in ideal and yawed conditions in the future. Experiments with the 1m research turbine under non-yawed and yawed operating conditions were planned, but due to COVID-19 shutdown the project pivoted to tasks that could be completed while working remotely.
