Canadian Standards Association (operating as “CSA Group”), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for- profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.

CSA Group standards reflect a national consensus of producers and users — including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.

More than 10 000 members indicate their support for CSA Group’s standards development by volunteering their time and skills to Committee work.

CSA Group offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, CSA Group regularly and continually audits and inspects products that bear the

CSA Group Mark.

In addition to its head office and laboratory complex in Toronto, CSA Group has regional branch offices in major centres across Canada and inspection and testing agencies in fourteen countries. Since 1919, CSA Group has developed the necessary expertise to meet its corporate mission: CSA Group is an independent service

organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

CSA C61400-1:21

Wind energy generation systems — Part 1:

Design requirements

(IEC 61400-1:2019, MOD)

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.

For brevity, this Standard will be referred to as “CSA C61400-1” throughout.

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 was reviewed for Canadian adoption by the CSA Subcommittee on Wind Turbines —

Part 1: Design Requirements, under the jurisdiction of the CSA Technical Committee on Wind Turbines and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee.

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.

Interpretations: The Strategic Steering Committee on Requirements for Electrical Safety has provided the following direction for the interpretation of standards under its jurisdiction: “The literal text shall be used in judging compliance of products with the safety requirements of this Standard. When the literal text cannot be applied to the product, such as for new materials or construction, and when a relevant CSA committee interpretation has not already been published, CSA Group’s procedures for interpretation shall be followed to determine the intended safety principle.”

Canadian deviations

The following deviations are intended to meet Canadian product requirements and to align with the

Canadian Electrical Code, Part I and the National Building Code of Canada.

Introduction

[Replace the first paragraph with the following]

This Standard specifies minimum design requirements for wind turbine installations in Canada and is not intended for use as a complete design specification or instruction manual.

The majority of current and proposed Canadian wind turbine installations are or will be located in environments that experience icing conditions more severe than and temperatures colder than the icing conditions and temperatures within the normal design ranges identified in IEC 61400-1. This fact has been a primary consideration in the development of the Canadian deviations to this Standard.
