CSA Group Wind turbines - Part 1: Design requirements (Adopted IEC 61400-1:2007, third edition, 2005-08, including amendment 1:2010, with Canadian deviations) CAN/CSA-C61400-1:14

Preface This is the second edition of CAN/CSA-C61400-1, Wind turbines - Part 1: Design requirements, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61400-1 (third edition, 2005-08), including Amendment 1:2010. It supersedes the previous edition published in 2008 as CAN/CSA-C61400-1 (adopted IEC 61400-1:2007). At the time of publication, IEC Amendment 1:2010 is available from IEC in English only. CSA Group will publish the French version when it becomes available from IEC. For brevity, this Standard will be referred to as "CAN/CSA-C61400-1" throughout. 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. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada (NRCan). Scope This part of IEC 61400 specifies essential design requirements to ensure the engineering integrity of wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime. This Standard is concerned with all subsystems of wind turbines such as control and protection mechanisms, internal electrical systems, mechanical systems and support structures. This Standard applies to wind turbines of all sizes. For small wind turbines IEC 61400-2 may be applied. This Standard should be used together with the appropriate IEC and ISO standards mentioned in Clause 2.
