Wind energy generation systems - Part 24: Lightning protection

IEC 61400-24:2019 applies to lightning protection of wind turbine generators and wind power systems. Refer to guidelines for small wind turbines in annex.
This document defines the lightning environment for wind turbines and risk assessment for wind turbines in that environment. It defines requirements for protection of blades, other structural components and electrical and control systems against both direct and indirect effects of lightning. Test methods to validate compliance are included.
Guidance on the use of applicable lightning protection, industrial electrical and EMC standards including earthing is provided.
This second edition cancels and replaces the first edition, published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a) it is restructured with a main normative part, while informative information is placed in annexes.

Systèmes de génération d’énergie éolienne - Partie 24: Protection contre la foudre

l’IEC 61400-24:2019 s’applique à la protection des aérogénérateurs et des parcs éoliens contre la foudre. Se reporter à l’Annexe M pour les lignes directrices applicables aux éoliennes de petite taille.Le présent document définit l’environnement de foudre applicable aux éoliennes et l’appréciation du risque pour ces mêmes éoliennes dans cet environnement. Il définit les exigences concernant la protection des pales, des autres composants structurels, ainsi que des réseaux de puissance et de commande contre les effets directs et indirects de la foudre. Les méthodes d’essai pour validation de la conformité sont incluses dans le présent document.Des recommandations relatives à l’utilisation des normes applicables en matière de protection contre la foudre, ainsi que des normes électriques industrielles et de CEM, y compris la mise à la terre sont fournies.
Cette deuxième édition annule et remplace la première édition parue en 2010. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) sa restructuration comprend une partie normative principale, les informations informatives étant intégrées dans des annexes.
