IEC 61400-50 specifies methods and requirements for the application of instruments to measure wind speed (and related parameters, e.g. wind direction and turbulence intensity). Such measurements are required as an input to some of the evaluation and testing procedures for wind energy and wind turbine technology (e.g. resource evaluation and turbine testing) described by other standards in the IEC 61400 series. This document is applicable specifically to the use of ground-mounted remote sensing wind measurement instruments, i.e. devices which measure the wind at some location generally above and distant from the location at which the instrument is mounted (e.g. sodars, vertical profiling lidars). This document specifically excludes other types of RSD such as forward facing or scanning lidars. This document specifies the following:
a) the procedure and requirements for classifying ground-based RSDs in order to assess the
uncertainty pertaining from sensitivity of the RSD response to meteorological conditions that
can vary between the RSD calibration place and time and the use case (specific
measurement campaign – SMC) place and time;
b) the procedures and requirements for calibration of RSDs;
c) the assessment of wind speed measurement uncertainty;
d) additional checks of the RSD performance and measurement uncertainty during the SMC;
e) application of the wind speed uncertainty derived from the RSD calibration and classification to the measurements taken during the SMC (e.g. interpolation of uncertainty or calibration results to different heights);
f) requirements for reporting.
