Communication networks and systems for power utility automation - Part 8-2: Specific communication service mapping (SCSM) - Mapping to Extensible Messaging Presence Protocol (XMPP)

EC 61850-8-2:2018 specifies a method of exchanging data through any kinds of network, including public networks. Among the various kinds of services specified in IEC 61850-7-2, only the client/server and time synchronization services are considered so far.
NOTE Client/server services of GOOSE and SMV models are mapped as well.
For the client/server services, the principle is to map the objects and services of the ACSI (Abstract Communication Service Interface defined in IEC 61850-7-2) to XML messages transported over XMPP. The mapping description includes mainly three aspects:
• The usage of the XMPP protocol itself, describing in details which features are really used and how they are used by the mapping.
• How to achieve end-to-end secured communications.
• The description of the XML payloads corresponding to each ACSI service thanks in particular to the XML Schema and XML message examples.

Réseaux et systèmes de communication pour l'automatisation des systèmes électriques - Partie 8-2 : Mapping des services de communication spécifiques (SCSM) - Mapping avec le protocole XMPP (Extensible Messaging Presence Protocol)

IEC 61850-8-2:2018 spécifie une méthode d'échange de données par tous types de réseaux, y compris les réseaux publics. Parmi les différents types de services spécifiés dans l'IEC 61850-7-2, seuls les services client/serveur et les services de synchronisation temporelle sont pris en considération.
NOTE Les services client/serveur des modèles GOOSE et SMV sont également mappés.
Pour les services client/serveur, le principe consiste à mapper les objets et les services de l'interface abstraite des services de communication (ACSI – Abstract Communication Service Interface) définie dans l'IEC 61850-7-2) aux messages XML transportés sur XMPP. La description du mapping inclut trois principaux aspects:
• L'utilisation du protocole XMPP lui-même, décrivant en détail les fonctions réellement utilisées et la manière dont le mapping les utilise.
• La manière d'obtenir des communications sécurisées de bout en bout.
• La description des données utiles XML correspondant à chaque service ACSI au moyen, en particulier, du schéma XML et des exemples de message XML.
