Communication networks and systems for power utility automation - Part 7-420: Basic communication structure - Distributed energy resources and distribution automation logical nodes
This part of IEC 61850 defines the IEC 61850 information models to be used in the exchange of information with distributed energy resources (DER) and Distribution Automation (DA) systems. DERs include distribution-connected generation systems, energy storage systems, and controllable loads, as well as facility DER management systems, including aggregated DER, such as plant control systems, facility DER energy management systems (EMS), building EMS, campus EMS, community EMS, microgrid EMS, etc. DA equipment includes equipment used to manage distribution circuits, including automated switches, fault indicators, capacitor banks, voltage regulators, and other power management devices. The IEC 61850 DER information model standard utilizes existing IEC 61850-7-4 logical nodes where possible, while defining DER and DA specific logical nodes to provide the necessary data objects for DER and DA functions, including for the DER interconnection grid codes specified by various countries and regions. Although this document explicitly addresses distribution-connected resources, most of the resource capabilities, operational functions, and architectures are also applicable to transmission-connected resources.

Réseaux et systèmes de communication pour l'automatisation des systèmes électriques - Partie 7-420: Structure de communication de base - Ressources énergétiques décentralisées et nœuds logiques d'automatisation de la distribution
IEC 61850-7-420:2021 définit les modèles d'information IEC 61850 à utiliser pour l'échange d'informations avec les systèmes de ressources énergétiques décentralisées (DER) et les systèmes d'automatisation de la distribution (DA). Les DER comprennent les systèmes de production raccordés à la distribution, les systèmes de stockage d'énergie et les charges modulables, ainsi que les systèmes de gestion DER de l'installation, notamment les DER agrégées, telles que les systèmes de commande d'installation, les systèmes de gestion d'énergie (EMS) DER de l'installation, les EMS de construction, les EMS de campus, les EMS de collectivité, les EMS de microréseau, etc. Les équipements d'automatisation de la distribution (DA, Distribution Automation) incluent les équipements utilisés pour la gestion des circuits de distribution, notamment les interrupteurs automatisés, les indicateurs de défaut, les batteries de condensateurs, les régulateurs de tension, ainsi que les autres dispositifs de gestion de l'énergie. La norme du modèle d'information IEC 61850 DER utilise les nœuds logiques IEC 61850-7-4 existants lorsque cela est possible tout en définissant des nœuds logiques DER et DA spécifiques pour fournir les objets de données nécessaires aux fonctions DER et DA, notamment pour les codes de réseau d'interconnexion DER spécifiés par les différents pays et régions. Même si le présent document traite explicitement des ressources raccordées au réseau de distribution électrique, la plupart des capacités de ressources, des fonctions opérationnelles et des architectures s'appliquent également aux ressources raccordées au réseau électrique de transport. Cette deuxième édition annule et remplace la première édition parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) approche générique de la modélisation pour prendre en charge tous les types de DER, y compris la production, le stockage et les charges modulables; b) approche générique pour prendre en charge les agrégations de DER virtuelles et physiques; c) prise en charge complète d'un large éventail de fonctions opérationnelles pour couvrir notamment les fonctions de codes de réseau décrites dans l'IEEE 1547 et l'EN 50549 ou l'IEC 62786.
Komunikacijska omrežja in sistemi za avtomatizacijo porabe električne energije - 7-420. del: Osnovna komunikacijska struktura - Porazdeljeni energijski viri in logična vozlišča avtomatizacije distribucije
V tem delu standarda IEC 61850 so opredeljeni informacijski modeli iz standarda IEC 61850, ki se uporabljajo pri izmenjavi informacij s sistemi porazdeljenih energijskih virov (DER) in avtomatizacije distribucije (DA). Sistemi porazdeljenih energijskih virov vključujejo proizvodne sisteme, povezane z distribucijskim omrežjem, sisteme za shranjevanje energije in obvladljive obremenitve ter sisteme za upravljanje porazdeljenih energijskih virov v obratih (vključno z združenimi sistemi), kot so regulacijski sistemi elektrarn, sistemi za upravljanje energije v obratih (EMS), sistemi za upravljanje energije v zgradbah, sistemi za upravljanje energije v skupnostih, sistemi za upravljanje energije v mikro omrežjih itd. Oprema za avtomatizacijo distribucije vključuje opremo, ki se uporablja za upravljanje razdelilnih tokokrogov, vključno z avtomatskimi stikali, kazalniki napak, kondenzatorskimi baterijami, regulatorji napetosti in drugimi napravami za upravljanje energije.
Standard informacijskega modela za porazdeljene energijske vire v skladu s standardom IEC 61850 uporablja obstoječa logična vozlišča iz standarda IEC 61850-7-4, kjer je to mogoče, ter obenem določa logična vozlišča, specifična za porazdeljene energijske vire in avtomatizacijo distribucije, s čimer se zagotovijo potrebni podatkovni objekti za funkcije porazdeljenih energijskih virov in avtomatizacije distribucije, vključno za omrežne kodekse medsebojne povezave porazdeljenih energijskih virov, ki jih določijo različne države in regije.
Čeprav ta dokument izrecno obravnava vire, povezane z distribucijskim omrežjem, je mogoče večino zmogljivosti virov, operativnih funkcij in arhitektur uporabiti tudi za prenosno povezane vire.
