IEC 60364-8-82:2022
(Main)Low-voltage electrical installations - Part 8-82: Functional aspects - Prosumer's low-voltage electrical installations
Low-voltage electrical installations - Part 8-82: Functional aspects - Prosumer's low-voltage electrical installations
IEC 60364-8-82:2022 provides requirements and recommendations that apply to low-voltage electrical installations connected or not to a distribution network able to operate:
– with local power supplies, and/or
– with local storage units,
and that monitors and controls the energy from the locally connected sources delivering it to:
– current-using equipment, and/or
– local storage units, and/or
– distribution networks.
Such electrical installations are designated as prosumer's electrical installations (PEIs).
These requirements and recommendations apply to new installations and modifications of existing installations.
This document also provides requirements and recommendations for the safe, efficient and correct behaviour of these installations when integrated into a smart grid.
Information related to grid interaction to ensure the stability of the electrical system for grid connected PEIs is given in Annex B.
This document covers the requirements related to stability of islanded and stand-alone PEIs.
This first edition cancels and replaces IEC 60364-8-2 published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC 6036482:2018:
a) the vocabulary and concepts have been aligned as much as possible with those used by TC 8 and SC 8B, taking notably into account the IEC 62898 and IEC 62786 series, still respecting the installers mindset (installers being the first users of the IEC 60364 series and being used to only refer to the IEC 60364 series);
b) the type of system earthing and the change of type of system earthing (sequencing) when there is a change of mode of the prosuming installation, have been clarified;
c) the conditions of connection and disconnection from the DSO network have also been described, both from the safety point of view and the proper functioning point of view;
d) additional requirements have been introduced;
e) the figures have been updated;
f) a new normative Annex D on single dwelling or similar application islandable PEIs has been added;
g) the numbering has also been reviewed to follow the updated numbering system of the IEC 60364 series, in line with the IEC Directives and compatible with Parts 7.
Installations électriques à basse tension - Partie 8-2: Aspects fonctionnels - Installations électriques à basse tension du prosommateur
IEC 60364-8-82:2022 spécifie les exigences et recommandations qui s'appliquent aux installations électriques à basse tension connectées ou non à un réseau de distribution capable de fonctionner:
– avec des alimentations électriques locales; et/ou
– avec des unités de stockage locales;
et qui surveille et commande l'énergie délivrée par les sources connectées en local afin d'alimenter:
– des matériels d'utilisation; et/ou
– des unités de stockage locales; et/ou
– les réseaux de distribution.
Ces installations électriques sont appelées installations électriques du prosommateur (PEI, Prosumer's Electrical Installations).
Ces exigences et recommandations s'appliquent aux installations neuves et aux modifications des installations existantes.
Le présent document spécifie également les exigences et recommandations relatives au comportement sûr, efficace et correct de ces installations lorsqu'elles sont intégrées dans un réseau intelligent.
Les informations relatives à l'interaction du réseau pour assurer la stabilité du système électrique des PEI connectées au réseau sont données à l'Annexe B.
Le présent document couvre les exigences relatives à la stabilité des PEI autonomes ou en réseau séparé.
Cette première édition annule et remplace l'IEC 60364-8-2 parue en 2018.
