Anotation

IEC 62855:2016 provides the electrotechnical engineering guidelines for analysis of AC and DC electrical power systems in nuclear power plants (NPPs) in order to demonstrate that the power sources and the distribution systems have the capability for safe operation and shut down of the NPP, bringing it to a controlled state after an anticipated operational occurrence or accident conditions and finally reaching a safe state. This standard is intended to be used: - for verification of the design of new nuclear power plants; - for demonstrating the adequacy and impact of major modifications of electrical power systems in operating nuclear power plants; - and where there is a requirement to assess and establish operating limits and constraints for existing plants. LIEC 62855:2016 donne les directives en matiere dingenierie electrotechnique pour lanalyse des systemes electriques de puissance en courant alternatif (CA) et en courant continu (CC) des centrales nucleaires (CNPE). Il sagit de demontrer que les sources de puissance et le systeme de distribution electrique peuvent garantir le fonctionnement et larret sur de la centrale, de maniere a atteindre un etat controle apres un incident de fonctionnement prevu, puis un etat sur. La presente norme a pour objectif detre utilisee: - pour verifier la conception des nouvelles centrales nucleaires de puissance; - pour demontrer la pertinence et limpact de modifications majeures apportees aux systemes electriques des CNPE en exploitation; - lorsque les centrales existantes font lobjet dune exigence devaluation et detablissement des limites ainsi que des contraintes de fonctionnement.
