Energy management system application program interface (EMS-API) - Part 452: CIM static transmission network model profiles

This IEC document is one of the IEC 61970-450 to 499 series that, taken as a whole, defines
at an abstract level the content and exchange mechanisms used for data transmitted between
control centers and/or control center components, such as power systems applications.
The purpose of this document is to define the subset of classes, class attributes, and roles
from the CIM necessary to execute state estimation and power flow applications. The North
American Electric Reliability Council (NERC) Data Exchange Working Group (DEWG)
Common Power System Modeling group (CPSM) produced the original data requirements,
which are shown in Annex E. 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 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.
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, the 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 standard 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.
Optional and required classes, attributes and associations must be imported if they are in the
model file prior to import. If an optional attribute does not exist in the imported file, it does not
have to be exported in case exactly the same data set is exported, i.e. the tool is not obliged
to automatically provide this attribute. If any mandatory attribute or association is missing, the
exchanged data is considered invalid. Specific business processes may relax restrictions of
the profile, but such exchanges would not be considered to be compliant with the standard.
Business processes governing different exchanges can also require mandatory exchange of
certain optional attributes or associations.
Furthermore, an exporter may, at his or her discretion, produce an XML data file containing
additional class data described by the CIM RDF Schema but not required by this document
provided these data adhere to the conventions established in Clause 6.
From the standpoint of the model import used by a data recipient, the document describes a
subset of the CIM that importing software must be able to interpret in order to import exported
models. As mentioned above, data providers are free to exceed the minimum requirements
described herein as long as their resulting data files are compliant with the CIM RDF Schema
and the conventions established in Clause 6. The document, therefore, describes additional
classes and class data that, although not required, exporters will, in all likelihood, choose to
include in their data files. The additional classes and data are labeled as required (cardinality
1..1) or as optional (cardinality 0..1) to distinguish them from their required counterparts.
Please note, however, that data importers could potentially receive data containing instances
of any and all classes described by the CIM RDF Schema.

Schnittstelle für Anwendungsprogramme für Netzführungssysteme (EMS-API) - Teil 452: CIM-Statische-Übertragungsnetzwerk-Modell-Profile

Interface de programmation d'application pour système de gestion d'énergie (EMS-API) - Partie 452: Profils du modèle de réseau de transport statique CIM

L'IEC 61970-452:2017 définit le sous-ensemble des classes, des attributs de classe et des rôles du CIM nécessaires à l’exécution des applications d’estimation d’état et de flux d’énergie. La présente norme s'adresse à deux destinataires distincts, les producteurs de données et les destinataires de données, et peut être interprété selon deux points de vue. Cette nouvelle édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: division du profil Equipment en trois profils distincts: CoreEquipment, Operation et ShortCircuit; remplacement du modèle CCHT par un nouveau modèle défini dans l'Édition 6 de l’IEC 61970-301.

Aplikacijski programski vmesnik za sistem upravljanja z energijo (EMS-API) - 452. del: Profili CIM za statični model prenosnega omrežja

Ta dokument IEC je eden iz skupine od IEC 61970-450 do 499, ki kot celota na abstraktni ravni določa vsebino in mehanizme izmenjave, ki se uporabljajo za podatke, prenesene med nadzornimi centri in/ali njihovimi komponentami, kot so aplikacije energetskega sistema.
Namen tega dokumenta je določiti podmnožice razredov, atributov razredov in vlog v skupnem informacijskem modelu (CIM), potrebnih za izvedbo aplikacij ocenjevanja stanj in pretoka moči. Svet NERC (North American Electric Reliability Council), delovna skupina DEWG (Data Exchange Working Group) in skupina CPSM (Common Power System Modeling) so predložili izvirne podatkovne zahteve, ki so navedene v dodatku E. Te zahteve temeljijo na predhodnih industrijskih praksah za izmenjavo podatkov modela energetskega sistema za uporabo predvsem pri načrtovalnih študijah. Vendar pa je seznam zahtevanih podatkov razširjen, da je olajšana izmenjava modelov, ki zajema parametre, ki so običajni za odklopniške aplikacije. Po potrebi ta dokument določa konvencije, prikazane v točki 6, s katerimi mora biti v skladu podatkovna datoteka XML, da se šteje kot veljavna za izmenjavo modelov.
Ta dokument je namenjen dvema ločenima skupinama (proizvajalcem podatkom in prejemnikom podatkov) in se lahko tolmači z dveh vidikov.
S stališča programske opreme za izvažanje modelov, ki jo uporablja proizvajalec podatkov, dokument opisuje najmanjšo podmnožico razredov CIM, atributov in povezav, ki morajo biti prisotni v podatkovni datoteki v obliki zapisa XML za izmenjavo modela. Vendar pa ta standard ne narekuje oblikovanja omrežja. Določa samo, katere razrede, atribute in povezave se uporablja za opisovanje izvirnega modela, takega kot je.
Izbirne in zahtevane razrede, atribute in povezave je treba uvoziti, če so pred uvozom v datoteki z modelom. Če izbirni atribut ne obstaja v uvoženi datoteki, ga ni treba izvoziti, če se izvozi povsem enak nabor podatkov, tj. orodju ni treba samodejno zagotoviti tega atributa. V primeru manjkajočega obveznega atributa ali povezave izmenjani podatki niso veljavni. Posebni poslovni procesi lahko omilijo omejitve profila, vendar se take izmenjave ne štejejo kot skladne s standardom.
Poslovni procesi, ki urejajo različne izmenjave, lahko zahtevajo tudi obvezno izmenjavo nekaterih izbirnih atributov ali povezav.
Poleg tega lahko izvoznik po lastni presoji izdela podatkovno datoteko XML z dodatnimi podatki o razredu, ki so opisani v shemi CIM RDF, vendar jih ta dokument ne zahteva, pod pogojem da so podatki v skladu s konvencijami v točki 6.
S stališča programske opreme za uvažanje modelov, ki jo uporablja prejemnik podatkov, dokument opisuje podmnožico razredov CIM, ki jih mora programska oprema za uvažanje znati interpretirati, da lahko uvozi izvožen model. Kot je navedeno zgoraj, lahko ponudniki podatkov presežejo minimalne zahteve, ki so opisane v tem dokumentu, če so njihove podatkovne datoteke v skladu s shemo CIM RDF in konvencijami, določenimi v točki 6. Zato dokument opisuje dodatne razrede in podatke razreda, ki jih bodo izvozniki zelo verjetno vključili v svoje podatkovne datoteke, čeprav niso zahtevani. Dodatni razredi in podatki so označeni kot zahtevani (kardinalnost 1..1) ali izbirni (kardinalnost 0..1), da jih je mogoče ločiti od potrebnih nasprotnih ustreznikov.
Upoštevajte, da uvozniki podatkov lahko prejmejo podatke, ki vsebujejo primere katerega koli in vseh razredov, ki jih opisuje shema CIM RDF.
