Anotation

IEC 61970-452:2021 defines the subset of classes, class attributes, and associations from the CIM necessary to execute state estimation and power flow applications between control centres and/or control centre components, such as power systems applications. The North American Electric Reliability Council (NERC) Data Exchange Working Group (DEWG) Common Power System Modelling group (CPSM) produced the original data requirements, which are shown in Annex F. These requirements are based on prior industry practices for exchanging power system model data for use primarily in planning studies. However, the list of required data has been extended starting with the first edition of this standard to facilitate a model exchange that includes parameters common to breaker-oriented applications. Where necessary this document establishes conventions, shown in Clause 6, with which an XML data file must comply in order to be considered valid for exchange of models. The data exchange use cases which this standard is meant to support are described in Annex A. The idea of a modelling authority as the source responsible for the modeling of a given region is described in Annex B. The concept of a boundary between regions is explained in Annex C. Annex D explains the processing of multiple profiles such as the three profiles described in this standard. The use of different curve styles to define ReactiveCapabilityCurve-s is explained in Annex E. This document is intended for two distinct audiences, data producers and data recipients, and may be read from two perspectives. From the standpoint of model export software used by a data producer, this document describes a minimum subset of CIM classes, attributes, and associations which must be present in an XML formatted data file for model exchange. This document does not dictate how the network is modelled, however. It only dictates what classes, attributes, and associations are to be used to describe the source model as it exists. This fourth edition cancels and replaces the third edition published in 2017. This edition constitutes a technical revision. It is based on the IEC 61970 UML version ‘IEC61970CIM17v40’, dated 2020-08-24. This edition includes the following significant technical changes with respect to the previous edition: a) The classes PowerElectronicsConnection, PowerElectronicsUnit and PowerElectronicsWindUnit are added to the Core Equipment profile. IEC 61970-452:2021 definit le sous-ensemble des classes, des attributs de classe et des associations du CIM necessaires a l’execution des applications d’estimation d’etat et de flux d’energie. Le groupe Common Power System Modeling (CPSM) de Data Exchange Working Group (DEWG) du North American Electric Reliability Council (NERC) a etabli les premieres exigences relatives aux donnees, presentees a l’Annexe F. Ces exigences sont fondees sur des pratiques industrielles anterieures pour l’echange des donnees du modele de reseau pour une utilisation essentiellement dans les etudes de planification. Cependant, la liste des donnees exigees a ete etendue, en commencant par la presente edition de cette norme, afin de faciliter un echange de modele qui inclut des parametres communs aux applications orientees disjoncteur. Le present document etablit si necessaire des conventions, presentees a l’Article 6, auxquelles un fichier de donnees XML doit satisfaire afin d’etre reconnu comme valide pour lechange de modeles. L’Annexe A donne une presentation detaillee des cas d’utilisation de l’echange de donnees que la presente norme est reputee prendre en charge. LAnnexe B donne une presentation detaillee dune autorite de modelisation comme responsable de la modelisation dune region donnee. LAnnexe C explique le concept dune frontiere entre les regions. LAnnexe D explique le traitement de profils multiples tels que les trois profils decrits dans la presente norme. LAnnexe F explique lutilisation des differents modeles de reseaux permettant de definir ReactiveCapabilityCurve. Le present document sadresse a deux destinataires distincts, les producteurs de donnees et les destinataires de donnees, et peut etre interprete selon deux points de vue. Du point de vue du logiciel d’exportation des modeles utilise par un producteur de donnees, le document decrit un sous-ensemble minimal de classes, d’attributs et d’associations du modele CIM. Ce sous-ensemble doit etre present dans un fichier de donnees formate XML pour l’echange des modeles. En revanche, la presente norme ne regit pas la maniere dont le reseau est modelise. Elle ne gere que les classes, les attributs et les associations qui doivent etre utilises pour decrire le modele source reel. Cette quatrieme edition annule et remplace la troisieme edition parue en 2017. Cette edition constitue une revision technique. Elle est fondee sur la version IEC 61970 UML "IEC61970CIM17v40", datee du 2020-08-24. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) les classes PowerElectronicsConnection, PowerElectronicsUnit et PowerElectronicsWindUnit sont ajoutees au profil CoreEquipment.
