标准摘要
[中文适用范围]： IEC 61400-1:2019+AMD1:2025 CSV 规定了确保风力涡轮机结构完整性的基本设计要求。其目的是在风力涡轮机计划使用寿命期间，提供适当的防护，以防止来自所有危害的损害。本文件涉及风力涡轮机的所有子系统，包括控制与保护功能、内部电气系统、机械系统和支持结构。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则为海上风力涡轮机安装提供了补充要求。本文件旨在与第2章中提到的适当IEC和ISO标准一起使用。与前一版相比，本版包含以下重大技术变更：a) 对参考文献和要求的总体更新和澄清；b) 扩展风力涡轮机类别，以适应热带气旋和高湍流；c) 正常湍流模型（NTM）中湍流标准差的威布尔分布；d) 更新设计载荷情况（DLCs），特别是DLC 2.1和DLC 2.2；e) 修正部分安全系数规范。修正案1（2019-09）和解释表1（2025-02）的内容已包含在本文件中。 [外文原描述]： IEC 61400-1:2019+AMD1:2025 CSV 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 1 (2019-09) and Interpretation sheet 1 (2025-02) have been included in this copy.
