Railway Applications - Fixed installations and rolling stock - Technical criteria for the coordination between power supply and rolling stock to achieve interoperability - Part 2: stability and harmonics

This European Standard, part 2 of EN 50388 is linked to prEN 50388 1 which describes the general items on technical criteria for the coordination between power supply and rolling stock to achieve interoperability This part 2 establishes the acceptance criteria according to prEN 50388 1:2017, 10.4 step 7 for compatibility between traction units and power supply, in relation to: - co-ordination between controlled elements and between them and resonances in the electrical infrastructure in order to achieve network system stability; - co-ordination of harmonic behaviour with respect of excitation of electrical resonances. The following electric traction systems are within scope: - railways; - guided mass transport systems that are integrated with railways; - material transport systems that are integrated with railways. Public three phase grid is out of scope. Railway dedicated grid is included. This European Standard is applied in accordance with the requirements in prEN 50388-1:2017, Clause 10. It does not apply retrospectively to rolling stock already in service. It is the aim of this part 2 to support acceptance of new elements (rolling stock or infrastructure) by specifying precise requirements and methods for demonstration of compliance. However, it is still admissible to use the process as defined in part 1 instead. The process of part 1 shall be applied if the case studied is not covered by part 2. This version of the standard only applies to AC systems. Later versions may include similar effects in DC networks in addition (see Annex D). Main phenomena identified and treated in this standard are: - electrical resonance stability; - low frequency stability; - overvoltages caused by harmonics. This European Standard is structured as showed in Table 1 (Table 1 only shows references to the most important sections). (...)

Bahnanwendungen - Ortsfeste Anlagen und Bahnfahrzeuge - Technische Kriterien für die Koordination zwischen Anlagen der Bahnenergieversorgung und Fahrzeugen zum Erreichen der Interoperabilität - Teil 2: Stabilität und Oberschwingungen

Diese Europäische Norm, Teil 2 von EN 50388, hängt mit prEN 50388 1 zusammen, die allgemein die tech-nischen Kriterien für die Koordination zwischen der Energieversorgung und dem Fahrzeugpark zur Errei¬chung der Interoperabilität beschreibt. Dieser Teil 2 umfasst die Annahmekriterien nach prEN 50388 1:2017, 10.4, Schritt 7, für die Kompatibilität zwischen den Triebfahrzeugeinheiten und der Energieversorgung in Bezug auf: – die Koordination zwischen gesteuerten Elementen sowie zwischen diesen und den Resonanzen in der elektrischen Infrastruktur, um die Systemstabilität eines Netzes zu erreichen; – die Koordination des Oberschwingungsverhaltens hinsichtlich der Erregung der elektrischen Resonan-zen. Der Anwendungsbereich gilt für die folgenden elektrischen Zugförderungssysteme: – Eisenbahnen; – spurgeführte Nahverkehrssysteme, die in Eisenbahnen integriert sind; – Materialtransportsysteme, die in Eisenbahnen integriert sind. Das öffentliche Drehstromnetz ist außerhalb des Anwendungsbereiches. Das bahnspezifische Netz gehört zum Anwendungsbereich. Diese Europäische Norm gilt in Übereinstimmung mit den in prEN 50388 1:2017, Abschnitt 10, aufgeführten Anforderungen. Sie gilt nicht rückwirkend für bereits im Betrieb befindliche Fahrzeugparks. Ziel dieses Teils 2 ist die Unterstützung der Abnahme neuer Elemente (neuer Fahrzeuge oder neuer Infra-struktur) durch die Festlegung präziser Anforderungen und Verfahren für den Nachweis der Konformität. Es ist jedoch weiterhin erlaubt, stattdessen das in Teil 1 festgelegte Verfahren anzuwenden. Das in Teil 1 beschriebene Verfahren muss angewendet werden, wenn der zu prüfende Fall nicht von Teil 2 umfasst ist. Diese Version der Norm gilt ausschließlich für Wechselstromsysteme. Spätere Versionen dürfen auch ähnli-che Effekte in Gleichstromnetzen umfassen (siehe Anhang D). Die in dieser Norm identifizierten und behandelten Hauptphänomene sind: – elektrische Resonanzstabilität; – Niederfrequenzstabilität; – durch Oberschwingungen verursachte Überspannungen. Diese Europäische Norm weist die in Tabelle 1 gezeigte Struktur auf (Tabelle 1 zeigt nur Referenzen zu den wichtigsten Abschnitten). Tabelle 1 – Struktur dieser Europäischen Norm ...

Applications ferroviaires - Installations fixes et matériel roulant - Critères techniques pour la coordination entre les installations fixes de traction électrique et le matériel roulant pour réaliser l’interopérabilité - Partie 2 : stabilité et harmoniques

La présente Norme européenne constitue la Partie 2 de l'EN 50388. Elle est associée au prEN 50388 1, qui décrit les éléments généraux relatifs aux critères techniques pour la coordination entre l'alimentation et le matériel roulant en vue d'assurer l'interopérabilité. La présente Partie 2 définit les critères d'acceptation selon le prEN 50388 1:2017, 10.4, étape 7, qui permettent la compatibilité entre les unités de traction et l'alimentation, en ce qui concerne : - la coordination entre les éléments commandés et entre ces mêmes éléments et les résonances de l'infrastructure électrique, afin d'assurer la stabilité du système dans le réseau ; - la coordination du comportement vis-à-vis des harmoniques par rapport à l'excitation des résonances électriques. Les systèmes de traction électrique suivants relèvent du domaine d'application de la présente norme : - les chemins de fer ; - les systèmes guidés de transport en commun qui sont intégrés avec les chemins de fer ; - les systèmes de transport de matériaux qui sont intégrés avec les chemins de fer. Le réseau public triphasé ne relève pas du domaine d'application de la présente norme. Le réseau dédié aux chemins de fer est couvert. La présente Norme européenne s'applique conformément aux exigences du prEN 50388-1:2017, Article 10. Elle ne s'applique pas rétroactivement aux matériels roulants déjà en service. La Partie 2 traite de l'acceptation des nouveaux éléments (matériel roulant ou infrastructure) et précise notamment les exigences et méthodes de démonstration de la conformité. Toutefois, l'utilisation du processus défini dans la Partie 1 demeure toujours admise. Le processus de la Partie 1 doit s'appliquer si le cas étudié n'est pas couvert par la Partie 2. La présente version de la norme s'applique uniquement aux systèmes en courant alternatif. Les dernières versions peuvent avoir des effets analogues dans les réseaux en courant continu (voir Annexe D). Les principaux phénomènes identifiés et traités dans la présente norme sont les suivants : - la stabilité de résonance électrique ; - la stabilité à basse fréquence ; - les surtensions dues aux harmoniques. Le Tableau 1 décrit la structure de la Norme européenne (le Tableau 1 ne donne que les références aux articles et paragraphes les plus pertinents).

54 1 Scope
55 This European Standard, part 2 of EN 50388 is linked to prEN 50388-1 which describes the general items on
56 technical criteria for the coordination between power supply and rolling stock to achieve interoperability
57 This part 2 establishes the acceptance criteria according to prEN 50388-1:2017, 10.4 step 7 for compatibility
58 between traction units and power supply, in relation to:
59 — co-ordination between controlled elements and between them and resonances in the electrical
60 infrastructure in order to achieve network system stability;
61 — co-ordination of harmonic behaviour with respect of excitation of electrical resonances.
62 The following electric traction systems are within scope:
63 — railways;
64 — guided mass transport systems that are integrated with railways;
65 — material transport systems that are integrated with railways.
66 Public three phase grid is out of scope. Railway dedicated grid is included.
67 This European Standard is applied in accordance with the requirements in prEN 50388-1:2017, Clause 10. It
68 does not apply retrospectively to rolling stock already in service.
69 It is the aim of this part 2 to support acceptance of new elements (rolling stock or infrastructure) by specifying
70 precise requirements and methods for demonstration of compliance. However, it is still admissible to use the
71 process as defined in part 1 instead. The process of part 1 shall be applied if the case studied is not covered
72 by part 2.
73 This version of the standard only applies to AC systems. Later versions may include similar effects in DC
74 networks in addition (see Annex D).
75 Main phenomena identified and treated in this standard are:
76 — electrical resonance stability;
77 — low frequency stability;
78 — overvoltages caused by harmonics.
79 This European Standard is structured as showed in Table 1 (Table 1 only shows references to the most
80 important sections).
