风能发电系统第1部分:设计要求

[中文适用范围]： 本部分 IEC 61400 规定了确保风力发电机工程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，以防止所有危害造成的损害。 本文档涉及风力发电机的所有子系统，如控制和保护机制功能、内部电气系统、机械系统和支撑结构。 本文档适用于所有尺寸的风力发电机。对于小型风力发电机，可以应用 IEC 61400-2。IEC 61400-3-1 为海上风力发电机安装提供了附加要求。 本文档旨在与第 2 条中提到的适当 IEC 和 ISO 标准一起使用。 [外文原描述]： IEC 61400-1:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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 1 (2019-09) and Interpretation sheet 1 (2025-02) have been included in this copy.
