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

1.1 General This part of IEC 61850 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 (see Table 1). 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 (see Clause 6). - How to achieve end-to-end secured communications (see Clause 7). - The description of the XML payloads corresponding to each ACSI service thanks in particular to the XML Schema and XML message examples (starting at Clause 9). NOTE 1 This document does not address the detailed usage of the XMPP protocol. NOTE 2 This document does not address system management services. NOTE 3 For the information of people familiar with the mapping defined in IEC 61850-8-1, the XML messages defined in the present document are derived from those defined in IEC 61850-8-1 but with an XML encoding instead of a binary one. In this way implementing gateways between IEC 61850-8-1 and IEC 61850-8-2 is very straightforward in both directions. However reading IEC 61850-8-1 is not necessary to understand the present document except when it is used in conjunction with one of the GOOSE mappings described in IEC 61850-8-1. 1.2 Namespace name and version This new section is mandatory for any IEC 61850 namespace (as defined by IEC 61850-7-1). The parameters which identify this release of the SCSM_8_2 namespace xmlns="http://www.iec.ch/61850/2018/SCSM_8_2" are: - Namespace Version: 2018 - Namespace Revision: A - Namespace Release: 1 - Namespace release date: 2018-12 Edition Publication date Webstore Namespace Edition 1.0 2018-12 IEC 61850-8-2:2018 IEC 61850-8-2:2018 1.3 Code Component distribution The Code Components included in this IEC standard are also available as electronic machine readable file at: http://www.iec.ch/tc57/supportdocuments/IEC_61850-8-2.2018_ed1.0.XSD.2018A1.full.zip The Code Component(s) included in this IEC standard are potentially subject to maintenance works and users shall select the latest release in the repository located at: https://www.iec.ch/tc57/supportdocuments. The latest version/release of the document will be found by selecting the file IEC 61850-8- 2.2018_ed1.0.XSD.{VersionStateInfo}.full.zip with the filed VersionStateInfo of the highest value.

Kommunikationsnetze und -systeme für die Automatisierung der elektrischen Energieversorgung - Teil 8-2: Spezifische Abbildung von Kommunikationsdiensten (SCSM) – Abbildungen auf erweiterbares Messaging Presence Protocol (XMPP)

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)

1.1 Généralités La présente partie de l'IEC 61850 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 (voir le Tableau 1). 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 (voir l'Article 6). - La manière d'obtenir des communications sécurisées de bout en bout (voir l'Article 7). - La description des données utiles XML correspondant à chaque service ACSI au moyen, en particulier, du schéma XML et des exemples de message XML (commençant à l'Article 9). NOTE 1 Le présent document ne concerne pas l'utilisation détaillée du protocole XMPP. NOTE 2 Le présent document ne concerne pas les services de gestion du système. NOTE 3 Pour l'information des personnes familiarisées avec le mapping défini dans l'IEC 61850-8-1, les messages XML définis dans le présent document sont déduits de ceux de l'IEC 61850-8-1, mais avec un codage XML en lieu et place du codage binaire. De cette manière, la mise en oeuvre de passerelles entre l'IEC 61850-8- 1 et l'IEC 61850-8-2 est très directe dans les deux sens. Toutefois, il n'est pas indispensable de lire l'IEC 61850-8- 1 pour comprendre le présent document, sauf s'il est utilisé conjointement avec l’un des mappings GOOSE décrits dans l'IEC 61850-8-1. 1.2 Nom et version d'espace de nommage Cette nouvelle section est obligatoire pour tous les espaces de nommage IEC 61850 (tels que définis par l'IEC 61850-7-1). Les paramètres qui définissent cette version de l’espace de nommage SCSM_8_2 xmlns="http://www.iec.ch/61850/2018/SCSM_8_2" sont les suivants: - Version de l'espace de nommage: 2018 - Révision de l'espace de nommage: A - Diffusion de l'espace de nommage: 1 - Date de diffusion de l'espace de nommage: 2018-12 Édition Date de publication Webstore Espace de nommage Édition 1.0 2018-12 IEC 61850-8-2:2018 IEC 61850-8-2:2018 1.3 Répartition des éléments de code Les éléments de code inclus dans la présente norme IEC sont également disponibles sous forme de fichier lisible par une machine électronique à l'adresse suivante: http://www.iec.ch/tc57/supportdocuments/IEC_61850-8-2.2018_ed1.0.XSD.2018A1.full.zip Les éléments de code inclus dans la présente norme IEC font potentiellement l'objet de travaux de maintenance, et l'utilisateur doit choisir la révision la plus récente dans le référentiel se trouvant à l'adresse suivante: http://www.iec.ch/tc57/supportdocuments.

Komunikacijska omrežja in sistemi za avtomatizacijo porabe električne energije - 8-2. del: Preslikave posebne komunikacijske storitve (SCSM) - Preslikave v XMPP (Extensible Messaging Presence Protocol)

Ta del standarda IEC 61850 določa metodo izmenjave podatkov prek vseh vrst omrežij, vključno z javnimi omrežji. Med različnimi vrstami storitev, določenih v standardu IEC 61850-7-2, se do sedaj upoštevajo samo storitve odjemalec/strežnik in storitve časovne sinhronizacije.
OPOMBA: Storitve odjemalec/strežnik modelov GOOSE in SMV so tudi preslikane (glej preglednico 1). Pri storitvah odjemalec/strežnik to pomeni preslikavo objektov in storitev sporočil ACSI (vmesnik storitve za abstraktno komunikacijo, opredeljen v standardu IEC 61850-7-2) v sporočila XML, ki se prenašajo prek XMPP. Opis preslikav vključuje zlasti tri vidike:
• Samo uporabo protokola XMPP s podrobnimi opisi, katere funkcije se dejansko uporabljajo in kako jih uporabljajo preslikave (glej 6. točko).
• Kako doseči varno komunikacijo od enega konca do drugega (glej 7. točko).
• Opis koristnih vsebin XML, ki ustrezajo posamezni storitvi ACSI predvsem zaradi primerov sheme XML sporočil XML (začetek pri 9. točki).
OPOMBA 1: Ta dokument ne obravnava podrobne uporabe protokola XMPP.
OPOMBA 2: Ta dokument ne obravnava storitev upravljanja sistemov.
OPOMBA 3: Za informacije osebam, ki so seznanjene s preslikavami, opredeljenimi v standardu IEC 61850-8-1: sporočila XML, opredeljena v tem dokumentu, so izpeljana iz sporočil, opredeljenih v standardu IEC 61850-8-1, pri čemer je namesto binarnega kodiranja uporabljeno kodiranje XML. Tako je uvajanje prehodov med standardoma IEC 61850-8-1 in IEC 61850-8-2 zelo neposredno v obeh smereh. Vendar pa standarda IEC 61850-8-1 ni treba prebrati za razumevanje tega dokumenta, razen kadar se uporablja skupaj z eno od preslikav GOOSE, ki so opisane v standardu IEC 61850-8-1.
