CSA C61400-1:21 Wind energy generation systems - Part 1: Design requirements (IEC 61400-1:2019, MOD)

standard by CSA Group, 08/01/2021

Full Description

CSA Preface

This 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.

Scope

This 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.
