Wind energy generation systems - Part 25-6: Communications for monitoring and control of wind power plants - Logical node classes and data classes for condition monitoring

IEC 61400-25-6:2016(E) specifies the information models related to condition monitoring for wind power plants and the information exchange of data values related to these models. This standard is to be used with other standards of the IEC 61400-25 series. This new edition includes the following significant technical changes with respect to the previous edition: - major restructuring of the data model to accommodate flexibility; removal of UFF58 format; - access to data using the standard reporting and logging functions; - recommendations for creating data names to accommodate flexibility.

Systèmes de production d'énergie éolienne - Partie 25-6: Communications pour la surveillance et la commande des centrales éoliennes - Classes de nœuds logiques et classes de données pour la surveillance d'état

l’IEC 61400-25-6:2016 spécifie les modèles d’information liés à la surveillance d’état pour les centrales éoliennes et l’échange d’information des valeurs de données liées à ces modèles. La présente norme doit être utilisée avec d'autres normes de la série CEI 61400-25. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - restructuration majeure du modèle de données afin d’obtenir la flexibilité necessaire - le format UFF58 n’est plus utilise. - l’accès aux données utilise désormais les fonctions normalisées d’établissement de rapports et de journalisation - les recommandations concernant la création de noms de données afin d’obtenir la flexibilité nécessaire

Ta del standarda IEC 61400-25 določa informacijske modele, ki se nanašajo na nadzor pogojev za vetrne elektrarne, in izmenjavo informacij o vrednostih podatkov, ki se nanašajo na te modele.
OPOMBA: skladnost s standardom IEC 61400-25-6 načeloma predpostavlja skladnost s standardi IEC 61400-25-2, IEC 61400-25-3 in IEC 61400-25-4.
Slika 2 prikazuje tok informacij sistema, ki z nadzorovanjem pogojev izvaja vzdrževanje na podlagi pogojev. Slika prikazuje, kako so vrednosti podatkov dodelane in skoncentrirate v toku informacij, kar se zaključi s končnim ciljem vzdrževanja na podlagi pogojev; dejanja, ki se izvajajo na podlagi izdanih delovnih nalogov za vzdrževalne ekipe, s čimer se vetrni elektrarni prepreči prekinitev zagotavljanja predvidene storitve.
