Site Calibration to IEC 61400-12-1: 2017 Annex C
Perform a site calibration prior to wind farm construction with a short met mast combined with a more flexible, mobile measurement device.
This measurement is required prior to performing a Power Performance Measurement to remove any terrain induced complexity in the flow that might cause a deviation in the free stream flow between mast and turbine location.
Conduct your site calibration according to IEC 61400-12-1:2017 Annex C.
Use site calibrations to inform Power Performance Measurements to ensure turbine manufacturers can accept data gathered.
A site calibration is a pre-construction measurement campaign to quantify the wind speed relationship between an upwind location (reference mast / Lidar location) and a to-be-constructed turbine location, using a short met mast and roaming Lidar.
