Anotation

IEC 61643-32:2017 describes the principles for selection, installation and coordination of SPDs intended for use in Photovoltaic (PV) systems up to 1 500 V DC and for the AC side of the PV system rated up to 1 000 V rms 50/60 Hz. The photovoltaic installation extends from a PV array or a set of interconnected PV-modules to include the associated cabling and protective devices and the inverter up to the connection point in the distribution board or the utility supply point. This part of IEC 61643 considers SPDs used in different locations and in different kinds of PV systems:PV systems located on the top of a building. PV systems located on the ground like free field power plants characterized by multiple earthing and a meshed earthing system. The term PV installation is used to refer to both kinds of PV systems. The term PV power plant is only used for extended free-field multi-earthed power systems located on the ground. For PV installations including batteries additional requirements may be necessary. The contents of the corrigendum of June 2019 have been included in this copy. IEC 61643-32:2017 decrit les principes de choix, dinstallation et de coordination des parafoudres destines a etre utilises dans les systemes photovoltaiques (PV) jusqua une tension maximale de 1 500 V en courant continu, et en courant alternatif dans un systeme photovoltaique d’une tension assignee maximale de 1 000 V en valeur efficace sous une frequence de 50 Hz/60 Hz. Une installation photovoltaique englobe a la fois un groupe photovoltaique ou un ensemble de modules photovoltaiques interconnectes, des dispositifs de cablage et de protection associes, ainsi que l’onduleur et le point de connexion dun tableau de distribution ou le point dalimentation du reseau. La presente partie de lIEC 61643 traite des parafoudres utilises dans differents emplacements et avec differents types de systemes photovoltaiques: Les systemes photovoltaiques situes au sommet dun batiment. Les systemes photovoltaiques au sol comme les centrales electriques en champ libre caracterisees par plusieurs mises a la terre et un systeme de mise a la terre maille. Le terme «installation photovoltaique» fait reference aux deux types de systemes photovoltaiques. Le terme «centrale photovoltaique» sapplique uniquement aux reseaux dalimentation etendus mis a la terre en des points multiples en champ libre au sol. Des exigences supplementaires peuvent etre necessaires pour les installations photovoltaiques comportant des batteries. Mots cles: SPD - surge protective device connectes aux installations photovoltaiques, parafoudres, PV Le contenu du corrigendum de juin 2019 a ete pris en consideration dans cet exemplaire.
