IEC 61400-12-2:2022规定了根据IEC 61400-2验证不被视为小型风力涡轮机的单台发电水平轴风力涡轮机的功率性能特性的程序。当特定操作或合同规范不符合IEC 61400.12-1中规定的要求时，应使用本文件。本文件的目的是提供一种统一的测量、分析方法，并报告使用风舱风速测量方法的单个发电风力涡轮机的功率性能特征。本文件仅适用于尺寸足够大的水平轴风力涡轮机- 安装的风速计不会显著影响通过风机转子和风舱周围的流量，因此不会影响风机的性能。IEC 61400-12-2第二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 61400－12-1:2017和IEC 61400相关的技术变更12？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 61400-12-2:2022 specifies a procedure for verifying the power performance characteristics of a single electricity-producing, horizontal axis wind turbine that is not considered to be a small wind turbine per IEC 61400-2. It is expected that this document be used when the specific operational or contractual specifications do not comply with the requirements set out in IEC 61400-12-1. The purpose of this document is to provide a uniform methodology of measurement, analysis, and reporting of power performance characteristics for individual electricity producing wind turbines utilising nacelle-anemometry methods. This document is intended to be applied only to horizontal axis wind turbines of sufficient size that the nacelle-mounted anemometer does not significantly affect the flow through the turbine’s rotor and around the nacelle and hence does not affect the wind turbine’s performance. This second edition of IEC 61400-12-2 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.
