IEC 61400-12-3:20 22规定了一个测量和分析程序，用于推导由于地形影响引起的风速修正，并适用于IEC 61400中描述的连接到电力网络的所有类型和尺寸的风力涡轮机的性能测试？12？1.该程序适用于特定位置的特定风力涡轮机的性能评估。IEC 61400这一部分的目的是提供一种统一的方法，确保用于确定风力涡轮机功率性能的现场校准测量和分析的一致性、准确性和再现性。本文件为现场校准的测量、分析和报告提供了指导，以便随后用于风力涡轮机的功率性能测试。IEC 61400-12-3的第一版是结构修订的一部分，取消并取代了性能标准IEC 61400-12-1:20 17和IEC 61400-12-2:20 13。结构修订版不包含与IEC 61400-12-1:20 17和IEC 61400？12？2:20 13，但与风测量、场地校准测量以及障碍物和地形评估相关的部分已被提取到单独的标准中。

IEC 61400-12-3:2022 specifies a measurement and analysis procedure for deriving the wind speed correction due to terrain effects and applies to the performance testing of wind turbines of all types and sizes connected to the electrical power network as described in IEC 61400？12？1. The procedure applies to the performance evaluation of specific wind turbines at specific locations. The purpose of this part of IEC 61400 is to provide a uniform methodology that will ensure consistency, accuracy and reproducibility in the measurement and analysis of a site calibration for use in the determination of the power performance of wind turbines. This document provides guidance in the measurement, analysis, and reporting of the site calibration for subsequent use in power performance testing for wind turbines.
This first edition of IEC 61400-12-3 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.
