IEC 61850-7-420:2009

Communication networks and systems for power utility automation - Part 7-420: Basic communication structure - Distributed energy resources logical nodes

IEC 61850-7-420:2009 defines IEC 61850 information models to be used in the exchange of information with distributed energy resources (DER), which comprise dispersed generation devices and dispersed storage devices, including reciprocating engines, fuel cells, microturbines, photovoltaics, combined heat and power, and energy storage. Utilizes existing IEC 61850-7-4 logical nodes where possible, but also defines DER-specific logical nodes where needed.

Réseaux et systèmes de communication pour l'automatisation des systèmes électriques - Partie 7-420: Structure de communication de base - Noeuds logiques de ressources énergétiques distribuées

IEC 61850-7-420:2009 définit les modèles d’information de l’IEC 61850 à utiliser dans l’échange d’informations avec les ressources énergétiques distribuées (DER), qui comprend les dispositifs de génération dispersée et les dispositifs de stockage dispersé, y compris les moteurs à mouvement alternatif, les piles à combustible, les microturbines, les photovoltaïques, la production combinée de chaleur et d’électricité, et le stockage de l’énergie.
La norme IEC 61850 relative au modèle d’information DER utilise les nœuds logiques existants de l’IEC 61850-7-4 lorsque cela est possible, mais définit également des nœuds logiques spécifiques aux DER lorsque cela est nécessaire.
