EN 62920:2017

Photovoltaic power generating systems - EMC requirements and test methods for power conversion equipment

IEC 62920:2017 specifies electromagnetic compatibility (EMC) requirements for DC to AC power conversion equipment (PCE) for use in photovoltaic (PV) power systems. The PCE covered by this document can be grid-interactive or stand-alone. It can be supplied by single or multiple photovoltaic modules grouped in various array configurations, and can be intended for use in conjunction with batteries or other forms of energy storage. This document covers not only PCE connected to a public low voltage AC mains network or other low voltage AC mains installation, but also PCE connected to a medium or high voltage AC network with or without step-down power transformers.

Systèmes de production d'énergie photovoltaïque - Exigences de CEM et méthodes d'essai pour les équipements de conversion de puissance

L'IEC 62920:2017 spécifie les exigences de compatibilité électromagnétique (CEM) pour les équipements de conversion de puissance (PCE) en courant continu et en courant alternatif utilisés dans les systèmes de production photovoltaïque (PV). Le PCE couvert par le présent document peut être couplé au réseau ou autonome. Il peut être alimenté par un ou plusieurs modules photovoltaïques disposés en différents groupes et peut être destiné à être utilisé avec des batteries ou d’autres formes de stockage de l’énergie. Le présent document couvre non seulement les PCE connectés à un réseau public en courant alternatif à basse tension ou à une autre installation secteur en courant alternatif à basse tension, mais aussi les PCE connectés à un réseau en courant alternatif à moyenne ou haute tension avec ou sans transformateur de puissance abaisseur.

Fotonapetostni energetski sistemi - Zahteve EMC in preskusne metode za opremo močnostnih pretvornikov

IEC 62920:2017 določa zahteve EMC za elektromagnetno združljivost za opremo močnostnih pretvornikov enosmerne v izmenično napetost za uporabo v fotonapetostnih energetskih sistemih. Močnostni pretvorniki, ki jih zajema ta dokument, so lahko mrežno interaktivni ali samostojni. Dobaviti jih je mogoče kot enega ali več fotonapetostnih modulov, združenih v različne konfiguracije, in jih je mogoče uporabiti v povezavi z akumulatorji ali drugimi oblikami shranjevanja energije. Ta dokument ne zajema le močnostnih pretvornikov, ki so povezani z javnim nizkonapetostnim omrežjem ali drugo nizkonapetostno omrežno napeljavo, temveč tudi močnostne pretvornike, ki so priključeni na omrežje srednje ali visoke izmenične napetosti s pretvorniki, ki omogočajo transformacijo navzdol, ali brez njih.
