Power line communication systems for power utility applications - Part 1: Planning of analogue and digital power line carrier systems operating over HV electricity grids (IEC 62488-1:2025 (EQV)

IEC 62488-1:2025 applies to the planning of analogue (APLC), digital (DPLC) and hybrid analogue-digital (ADPLC) power line carrier communication systems operating over HV electric power networks. The object of this document is to establish the planning of the services and performance parameters for the operational requirements to transmit and receive data efficiently and reliably.
Such analogue and digital power line carrier systems are used by the different electricity supply industries and integrated into their communication infrastructure using common communication technologies such as radio links, fibre optic and satellite networks
This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Complete revision of this edition with respect to the previous edition with the main focus on planning of analogue and digital power line carrier systems operating over HV power networks;
b) A general structure of a bidirectional point-to-multipoint APLC, DPLC or ADPLC link has been introduced;
c) Introduction of a new approach for global frequency planning.

IEC 62488-1:2025 s’applique à la conception des systèmes de communication par courant porteur sur ligne d’énergie analogiques (APLC), numériques (DPLC) et hybrides analogiques/numériques (ADPLC, Analogue-Digital Power Line Carrier) installés sur des réseaux d’alimentation électrique HT. Le présent document a pour objet de définir la conception des services et des paramètres de performance relatifs aux exigences opérationnelles en matière d’émission et de réception efficaces et fiables des données.
Ces systèmes à courant porteur sur ligne d’énergie analogiques et numériques sont utilisés par les différentes compagnies d’électricité et sont intégrés à leur infrastructure de communication à l’aide des technologies de communication habituelles (les liaisons radioélectriques, la fibre optique et les réseaux satellite, par exemple).
Cette deuxième édition annule et remplace la première édition parue en 2012. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) Révision complète de la présente édition par rapport à l'édition précédente, portant principalement sur la conception des systèmes à courants porteurs de lignes d’énergie analogiques et numériques fonctionnant sur des réseaux d’électricité HT;
b) Une structure générale d’une liaison bidirectionnelle point à multipoint APLC, DPLC ou ADPLC a été introduite;
c) Introduction d’une nouvelle approche en matière de planification globale des fréquences.
