Overview of a wake imaging system

Wind turbine wakes lead to lower power production and increased loading on downstream turbines from the reduced incoming velocity and increased turbulence contained within the wakes. Detailed measurement will improve the understanding of the wakes needed to improve wake modeling and consequently support reducing cost of energy (COE) at the plant level. Sandia National Lab
