IEC 61400-12:2022规定了评估风力涡轮机功率性能特征的程序。本文件概述了可用的功率性能测量选项和贡献评估，IEC 61400-12系列的其他部分对此进行了详细说明。IEC 61400-12第一版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相关的技术变更- 2017年12月1日和IEC 6140012？2: 2013年，但与风测量、现场校准测量以及障碍物和地形评估相关的部分已提取到单独的标准中。

IEC 61400-12:2022 defines procedures for assessing the power performance characteristics of wind turbines. This document provides a general introduction to the available options for power performance measurement and the contributing evaluations which are further detailed in the other parts of the IEC 61400-12 series. This first edition of IEC 61400-12 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.
