Surge analysis on wind farm when winter lightning strikes / Yasuda, Y. in IEEE transactions on energy conversion, Vol. 23 N°1 (Mars 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 N°1 (Mars 2008) . - pp. 257 - 262 Titre : Surge analysis on wind farm when winter lightning strikes Type de document : texte imprimé Auteurs : Yasuda, Y., Auteur ; Uno, N., Auteur ; Kobayashi, H., Auteur Année de publication : 2008 Article en page(s) : pp. 257 - 262 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Power  system  protection;  power  system  simulation;  sensitivity  analysis;  surge  protection;  wind  power  plants;  wind  turbines Résumé : The rapid expansion of wind power generation has brought problems involving lightning strikes to the fore. Many such incidents have damaged not only the wind turbine that was actually struck but also other turbines that were not, a phenomenon that has yet to be fully explained. In this paper, the authors present a case study using a wind farm model with multiple wind turbines connected to a power system. The aim is to clarify the influence of the grounding system on surge propagation from a wind turbine that has been struck to others which have not, during a winter lightning strike. Sensitivity analyses show that the surge propagated to nearby wind turbines can sometimes become large, depending on the conditions of the grounding system, and result in the burnout of surge arresters in turbines that have not been struck, especially during winter lightning strikes.
