EN IEC 62590-1:2025

Railway applications - Electronic power converters for fixed installations - Part 1: General requirements

IEC 62590-1:2025 specifies the common requirements and definitions for all power converter applications in fixed installations for power supply of railway systems. This document applies to fixed installations of following electric traction systems: railway networks, metropolitan transport networks including metros, tramways, trolleybuses and fully automated transport systems, magnetic levitated transport systems, electric road systems. This document applies to AC/DC converters, DC converters and AC converters. Converters for improvement of power quality and for energy saving are also included. Converters connected to electric traction systems feeding 3AC, 1AC or DC systems for auxiliary purpose are not in the scope of this document but some aspects such as insulation coordination and railway specific conditions can be referred to. This document, in conjunction with the other parts of IEC 62590, cancels and replaces IEC 62589:2010 and the former IEC 62590:2019. This document includes the following significant technical changes with respect to IEC 62589:2010 and the former IEC 62590:2019: a) Split into common requirements and special requirements for different converters; b) Interface Model for the different systems connected; c) Split into circuits with their requirements like insulation coordination; d) Energy efficiency addressed.

Applications ferroviaires - Convertisseurs électroniques de puissance pour installations fixes - Partie 1: Exigences générales

La CEI 62590-1: 2025 spécifie les exigences communes et les définitions pour toutes les applications de convertisseurs de puissance dans les installations fixes pour l'alimentation électrique des systèmes ferroviaires. Ce document s'applique aux installations fixes des systèmes de traction électrique suivants : réseaux ferroviaires, réseaux de transport métropolitain, y compris les métros, les tramways, les trolleybus et les systèmes de transport entièrement automatisés, les systèmes de transport à sustentation magnétique, les systèmes routiers électriques. Ce document s'applique aux convertisseurs CA/CC, aux convertisseurs CC et aux convertisseurs CA. Les convertisseurs destinés à améliorer la qualité de l'énergie et à économiser l'énergie sont également inclus. Les convertisseurs connectés aux systèmes de traction électrique alimentant des systèmes 3AC, 1AC ou DC à des fins auxiliaires n'entrent pas dans le champ d'application du présent document, mais certains aspects tels que la coordination de l'isolation et les conditions spécifiques aux chemins de fer peuvent être mentionnés. Le présent document, conjointement avec les autres parties de la CEI 62590, annule et remplace la CEI 62589:2010 et l'ancienne CEI 62590:2019. Ce document inclut les changements techniques significatifs suivants par rapport à la CEI 62589:2010 et à l'ancienne CEI 62590:2019 : a) Séparation en exigences communes et en exigences spéciales pour les différents convertisseurs ; b) Modèle d'interface pour les différents systèmes connectés ; c) Séparation en circuits avec leurs exigences, comme la coordination de l'isolation ; d) L'efficacité énergétique est prise en compte.
