CSA序言这是CSA C61400-1《风能发电系统第1部分:设计要求》的第三版，采用了同名的IEC（国际电工委员会）标准61400-1（第四版，2019-02），但有加拿大的偏差。它取代了2014年发布的前一版本，即CAN/CSA-C61400-1（采用IEC 61400-1:2007），风力涡轮机-第1部分:设计要求。本标准拟与CSA C22结合使用。2 No.272:20，风力涡轮机电气系统。加拿大偏差反映了电气、环境和结构安全要求的本质差异，并为更广泛的加拿大外部条件提供了额外的要求和指导。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。 CSA集团已将其作为加拿大国家标准发布。范围IEC 61400的本部分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内提供适当级别的保护，防止所有危险造成的损害。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，可采用IEC 61400-2。IEC 61400-3-1提供了海上风力涡轮机安装的附加要求。本文件拟与第2条中提及的适当IEC和ISO标准一起使用。

CSA PrefaceThis is the third edition of CSA C61400-1, Wind energy generation systems - Part 1: Design requirements, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61400-1 (fourth edition, 2019-02). It supersedes the previous edition, published in 2014 as CAN/CSA-C61400-1 (adopted IEC 61400-1:2007), Wind turbines - Part 1: Design requirements. This Standard is intended to be used in conjunction with CSA C22.2 No. 272:20, Wind turbine electrical systems. The Canadian deviations reflect essential differences for electrical, environmental, and structural safety requirements and provide additional requirements and guidance for the broader range of Canadian external conditions. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.ScopeThis part of IEC 61400 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.
