Anotation

IEC 61400-26-1:2019 defines an information model from which time-based, and production-based availability indicators for services can be derived and reported. The purpose is to provide standardised metrics that can be used to create and organise methods for availability calculation and reporting according to the user’s needs. The document provides information categories, which unambiguously describe how data is used to characterise and categorise the operation. The information model specifies category priority for discrimination between possible concurrent categories. Further, the model defines entry and exit criteria to allocate fractions of time and production values to the proper information category. A full overview of all information categories, exit and entry criteria is given in Annex. The document can be applied to any number of WTGSs, whether represented by an individual turbine, a fleet of wind turbines, a wind power station or a portfolio of wind power stations. A wind power station is typically made up of all WTGSs, functional services and balance of plant elements as seen from the point of common coupling. This first edition cancels and replaces IEC TS 61400-26-1:2011, IEC TS 61400-26-2:2014 and IEC TS 61400-26-3:2016. lIEC 61400-26-1:2019 definit un modele dinformations a partir duquel peuvent etre deduits et consignes les indicateurs de disponibilite temporelle et en production des services. Il sagit de fournir des mesures normalisees pouvant etre utilisees pour creer et organiser des methodes de calcul et de declaration de la disponibilite en fonction des besoins de lutilisateur. Le present document fournit des categories dinformations, qui decrivent clairement la maniere dont les donnees sont utilisees pour caracteriser et categoriser le fonctionnement. Le modele dinformations specifie une priorite de categorie permettant de distinguer les differentes categories concurrentes possibles. En outre, le modele definit les criteres dentree et de sortie permettant dattribuer des fractions de temps et des valeurs de production a la categorie dinformations adequate. Une vue densemble de toutes les categories dinformations, des criteres dentree et des criteres de sortie est fournie a lannexe. Le present document peut etre applique a un certain nombre daerogenerateurs (eolienne individuelle, parc deoliennes, centrale eolienne ou ensemble de centrales eoliennes). Une centrale eolienne est generalement composee de lensemble des aerogenerateurs, services fonctionnels et elements dinstallation de production denergie, consideres par rapport au point de couplage commun (PCC). Cette premiere edition annule et remplace lIEC TS 61400-26-1:2011, lIEC TS 61400-26-2:2014 and lIEC TS 61400-26-3:2016.
