Wind Turbine Load Measurement in the Wake over the hill

The objective of this configuration was to measure the load of a wind turbine operating in the wake

of another wind turbine over the hill as shown in Figure A.1. The 1st wind turbine was located at

X=-L. The 2nd wind turbine was located at X=-L/2, X = 0, X = L/2, and X = L. Both wind turbines

had a diameter D = 0.512 m. The inlet wind velocity was 7 m/s. The forces acting on wind turbine

in X, Y, and Z directions as well as the moments around X, Y, and Z directions were measured

using a 6 component load cell.
