IEC 61400-13:2015（B）描述了用于负载模拟模型验证的风力涡轮机基本结构负载的测量。本标准规定了选址、信号选择、数据采集、校准、数据验证、测量负载情况、捕获矩阵、后处理、不确定度测定和报告的要求和建议。还提供了资料性附录，以提高对测试方法的理解。本标准取代了2001年发布的IEC TS 61400-13；它是一次技术修订，是从技术规范向国际标准的过渡。

IEC 61400-13:2015(B) describes the measurement of fundamental structural loads on wind turbines for the purpose of the load simulation model validation. The standard prescribes the requirements and recommendations for site selection, signal selection, data acquisition, calibration, data verification, measurement load cases, capture matrix, post-processing, uncertainty determination and reporting. Informative annexes are also provided to improve understanding of testing methods. This standard replaces IEC TS 61400-13 published in 2001; it constitutes a technical revision and transition from technical specification to International Standard.
