Energy management system application program interface (EMS-API) - Part 456: Solved power system state profiles

IEC 61970-456:2013 defines the subset of classes, class attributes, and roles from the CIM necessary to describe the result of state estimation, power flow and other similar applications that produce a steady-state solution of a power network, under a set of use cases which are included informatively in this standard. This standard is intended for two distinct audiences, data producers and data recipients, and may be read from those two perspectives. From the standpoint of model export software used by a data producer, the standard describes how a producer may describe an instance of a network case in order to make it available to some other program. From the standpoint of a consumer, the standard describes what that importing software must be able to interpret in order to consume solution cases.

Interface de programmation d'application pour système de gestion d'énergie (EMS-API) - Partie 456: Profils d'état de réseaux électriques résolus

La CEI 61970-456:2013 définit le sous-ensemble de classes, les attributs de classe et les rôles du CIM, nécessaires pour décrire le résultat de l'estimation d'état, du calcul de répartition et d'autres applications similaires produisant une solution en régime établi d'un réseau électrique dans un ensemble de cas d'utilisation inclus à titre informatif dans la présente norme. La présente norme vise deux publics différents, les producteurs de données et les utilisateurs de données. Elle peut être lue de ces deux points de vue. Du point de vue du logiciel d'exportation de modèles utilisé par un producteur de données, la présente norme présente la façon dont un producteur peut décrire une instance d'un cas de réseau pour le rendre accessible à un autre programme. Du point de vue du client, la présente norme décrit ce que ce logiciel d'importation doit être capable d'interpréter afin de pouvoir absorber les cas de solution du client.

Programski vmesnik za sistem za upravljanje energije (EMS-API) - 456. del: Profili stanja sproščenega elektroenergetskega sistema

Ta del standarda IEC 61970 pripada skupini od IEC 61970-450 do IEC 61970-499, ki kot celota na abstraktni ravni določa vsebino in mehanizme izmenjave, ki se uporabljajo za podatke, prenesene med nadzornimi centri in njihovimi komponentami. Namen tega dela standarda IEC 61970 je natančna definicija podmnožice razredov, atributov razredov in vlog v skupnem informacijskem modelu (CIM), potrebnih za opis rezultata ocenjevanja stanj, pretoka moči in drugih podobnih aplikacijah, ki ustvarijo ustaljeno rešitev napajalnega omrežja na podlagi množice primerov uporabe, ki jih ta standard informativno vključuje. Ta standard je namenjen dvema ločenima skupinama (proizvajalcem podatkom in prejemnikom podatkov) in se lahko tolmači na podlagi teh dveh vidikov. S stališča programske opreme za izvažanje modelov, ki jo uporablja proizvajalec podatkov, standard opisuje, kako lahko proizvajalec opiše omrežni primer, da omogoči njegovo razpoložljivost drugemu programu. S stališča porabnika standard opisuje, katere zmogljivosti tolmačenja mora vključevati programska oprema za uvažanje, da lahko porablja primere rešitev. Obstajajo številni različni primeri uporabe, pri katerih je pričakovana uporaba tega standarda in ki se razlikujejo v načinu uporabe standarda. Izvajalci določijo, katere primere uporabe želijo zajeti, da določijo obseg različnih možnosti, ki morajo biti vključene. Ta standard se na primer uporabi v nekaterih primerih za izmenjavo začetnih pogojev namesto izpolnjenih pogojev. Če je to pomemben primer uporabe, to pomeni, da mora biti porabniška aplikacija zmožna obravnavati tako neizpolnjeno stanje kot tudi stanje, pri katerem so bili izpolnjeni nekateri kriteriji rešitve.
