IEC 61400-1:20 19作为IEC 61400-1:20 19 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61400-1:20 19规定了确保风力涡轮机结构完整性的基本设计要求。其目的是在计划寿命期间提供适当水平的保护，防止所有危险的损害。本文件涉及风力涡轮机的所有子系统，如控制和保护功能、内部电气系统、机械系统和支撑结构。本文件适用于所有尺寸的风力涡轮机。对于小型风力涡轮机，可以应用IEC 61400-2。IEC 61400-3-1提供了海上风力涡轮机安装的附加要求。本文件旨在与第2条中提及的适当IEC和ISO标准一起使用。与上一版相比，此版本包括以下重大技术变更:a)参考文献和要求的一般更新和澄清；b)扩展风力涡轮机类别以适应热带气旋和高湍流；c）正态湍流模型（NTM）的湍流标准偏差的威布尔分布；d)更新的设计载荷工况，特别是DLC 2.1和2.2；e)部分安全系数质量标准的修订2019年9月勘误的内容已纳入本副本。

IEC 61400-1:2019 is available as IEC 61400-1:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61400-1:2019 specifies essential design requirements to ensure the structural integrity of wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime. This document is concerned with all subsystems of wind turbines such as control and protection functions, internal electrical systems, mechanical systems and support structures. This document applies to wind turbines of all sizes. For small wind turbines, IEC 61400-2 can be applied. IEC 61400-3-1 provides additional requirements to offshore wind turbine installations. This document is intended to be used together with the appropriate IEC and ISO standards mentioned in Clause 2. This edition includes the following significant technical changes with respect to the previous edition:
a) general update and clarification of references and requirements;
b) extension of wind turbine classes to allow for tropical cyclones and high turbulence;
c) Weibull distribution of turbulence standard deviation for normal turbulence model (NTM);
d) updated design load cases (DLCs), in particular DLC 2.1 and 2.2;
e) revision of partial safety factor specifications
The contents of the corrigendum of September 2019 have been included in this copy.
