IEC 61400-50-2:2022特别适用于地面安装遥感测风仪器的使用，即在通常位于仪器安装位置上方和远处的某个位置测量风的设备（例如，声纳、垂直剖面激光雷达）。本文件明确排除了其他类型的RSD，如前向或扫描激光雷达。本文件规定了以下内容:a.对地面RSD进行分类的程序和要求，以评估RSD响应对气象条件敏感性的不确定性，气象条件可能在RSD校准地点和时间以及用例（特定测量活动-SMC）地点和时间之间变化；b、 RSD校准程序和要求；c、 风速测量不确定度评估；d、 在SMC期间，对RSD性能和测量不确定性进行额外检查； e、 将RSD校准和分类得出的风速不确定性应用于SMC期间的测量（例如，将不确定性或校准结果插值到不同高度）；f、 报告要求。本第一版IEC 61400-50-2是结构修订版的一部分，该版本取消并取代了性能标准IEC 61400-12-1:2017和IEC 61400.12-2:2013。结构修订版不包含与IEC 61400-11-2:2017和IEC61400-12-2:2013相关的技术变更，但包含与风测量相关的部分，现场校准测量和障碍物和地形评估已提取到单独的标准中。

IEC 61400-50-2:2022 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. This first edition of IEC 61400-50-2 is part of a structural revision that cancels and replaces the performance standards IEC 61400-12-1:2017 and IEC 61400-12-2:2013. The structural revision contains no technical changes with respect to IEC 61400-12-1:2017 and IEC 61400-12-2:2013, but the parts that relate to wind measurements, measurement of site calibration and assessment of obstacle and terrain have been extracted into separate standards.
