Energy management system application program interface (EMS-API) - Part 301: Common information model (CIM) base

IEC 61970-301:2011 deals with the common information model (CIM), an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. The object classes represented in the CIM are abstract in nature and may be used in a wide variety of applications. The use of the CIM goes far beyond its application in an EMS. This standard should be understood as a tool to enable integration in any domain where a common power system model is needed to facilitate interoperability and plug compatibility between applications and systems independent of any particular implementation. Major changes from the second edition include the following: - Addition of regulation control models; - new 'OperationalLimits' package for equipment ratings; - addition of partial ownership specification; - enhancement of LoadResponseCharacteristic; - change from non-SI units to SI units.

Interface de programmation d'application pour système de gestion d'énergie (EMS-API) - Part 301: Base de modèle d'information commun (CIM)

La CEI 61970-301:2011 traite du modèle d'information commun (CIM), un modèle abstrait qui représente tous les objets principaux d'une entreprise de service public de distribution d'électricité habituellement impliqués dans les opérations de l'entreprise. Les classes d'objets représentées dans le CIM sont de nature abstraite et peuvent être utilisées dans une large gamme d'applications. L'utilisation du CIM n'est pas limitée à son application dans un EMS. Il convient que cette norme soit comprise comme un outil permettant l'intégration dans tout domaine où un modèle commun de réseau est nécessaire pour faciliter l'interopérabilité et la compatibilité de connexion entre des applications et des systèmes indépendants de toute implémentation particulière. Les principales modifications par rapport à la deuxième édition sont les suivantes: - ajout des modèles de commande de régulation; - nouveau paquetage 'OperationalLimits'; - ajout d'une spécification relative à la propriété partielle; - renforcement de la classe LoadResponseCharacteristic; - changement des unités non-SI en unités SI.

Aplikacijski programski vmesnik za sistem upravljanja z energijo (EMS-API) - 301. del: Osnova skupnega informacijskega modela (CIM)

Ta del IEC 61970 obravnava skupni informacijski model (CIM), abstraktni model, ki predstavlja vse glavne objekte v elektropodjetju, ki je običajno vključeno v postopke storitev zagotavljanja javnih dobrin. Razredi objektov, predstavljenih v CIM, so po svoji naravi abstraktni in se lahko uporabljajo pri zelo različnih aplikacijah. Uporaba CIM ni omejena le na uporabo pri sistemu upravljanja z energijo. Ta standard naj se razume kot orodje, ki omogoča integracijo v vsa področja, kjer je potreben skupni model elektroenergetskega sistema, ki omogoča medoperabilnost in združljivost med aplikacijami in sistemi, neodvisno od konkretne izvedbe. Z zagotovitvijo standardnega načina predstavljanja virov elektroenergetskih sistemov v obliki razredov in atributov objektov, skupaj z njihovimi medsebojnimi odnosi, CIM omogoča integracijo aplikacij sistema upravljanja energije, ki so jih neodvisno razvili različni dobavitelji, ali med sistemom upravljanja energije in drugimi sistemi, ki obravnavajo druge vidike delovanja elektroenergetskih sistemov, kot je upravljanje proizvodnje ali distribucije. SCADA (nadzor in zajemanje podatkov) je toliko modeliran, kolikor je potrebno za podporo simulacije elektroenergetskega sistema in komunikacijo med nadzornimi centri. CIM pospešuje integracijo z opredelitvijo skupnega jezika (tj. semantike in sintakse), osnovanega na CIM, ki omogoča, da imajo te aplikacije ali sistemi dostop do javnih podatkov in izmenjujejo informacije neodvisno od tega, kako so te informacije izražene interno. Zaradi velikosti celotnega CIM so razredi objektov, ki jih vsebuje CIM, razvrščeni v določeno število logičnih paketov, od katerih vsak predstavlja določen del skupnega elektroenergetskega sistema, ki se modelira. Zbirke teh paketov se razvijajo kot ločeni mednarodni standardi. Ta konkretni mednarodni standard določa osnovni nabor paketov, ki zagotavljajo logični pregled funkcionalnih vidikov informacij o sistemih upravljanja energije v elektropodjetju, ki si ga delijo vse aplikacije. Drugi standardi določajo bolj specifične dele modela, ki jih potrebujejo le določene aplikacije. Podtočka 4.2 navaja trenutno razvrščanje paketov v standardne dokumente.
