Communication networks and systems in substations - Part 7-420: Communications systems for distributed energy resources (DER) - Logical nodes (IEC 61850-7-420:2009)

This International Standard defines the 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. The IEC 61850 DER information model standard utilizes existing IEC 61850-7-4 logical nodes where possible, but also defines DER-specific logical nodes where needed.

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.

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technic
