Annotation of standard text IEC 61400-1-ed.4.0 :
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. lIEC 61400-1:2019 specifie les exigences de conception essentielles pour assurer l’integrite structurelle des eoliennes. Elle a pour objet de fournir un niveau de protection approprie contre les dommages causes par tous les dangers pendant la duree de vie prevue. Le present document concerne tous les sous-systemes des eoliennes tels que les fonctions de commande et de protection, les systemes electriques internes, les systemes mecaniques et les structures de support. Le present document sapplique aux eoliennes de toutes dimensions. Pour les petites eoliennes, lIEC 61400-2 peut s’appliquer. LIEC 61400-3-1 donne les exigences supplementaires relatives aux installations deoliennes en pleine mer. Le present document est destine a etre utilise avec les normes IEC et ISO appropriees mentionnees a l’Article 2. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a. mise a jour generale et clarification des references et des exigences; b. extension des classes deoliennes pour les adapter aux cyclones tropicaux et aux fortes turbulences; c. loi de Weibull de lecart type de la turbulence pour le modele de turbulence normale (NTM); d. cas de charge pour la conception (DLC) mis a jour, en particulier les DLC 2.1 et 2.2; e. revision des specifications du facteur de securite partielle Le contenu de la feuille d’interpretation 1 (2025-02) a ete pris en consideration dans cet exemplaire
