Railway applications - Fixed installations - Requirements for the validation of simulation tools used for the design of electric traction power supply systems
This document specifies requirements for the acceptance of simulation tools used for the assessment of design of electric traction power supply systems with respect to TSI Energy. This document is applicable to the simulation of AC and DC electric traction power supply systems, in the frame of assessment required by Directive (EU) 2016/797. The methods and parameters defined in this document are only intended for use in the design of the electric traction power supply system, and hence this document solely considers validation of tools within the TSI energy subsystem for all envisaged railway networks. This document does not deal with validation of simulation tools by measurement. This document focuses on the core simulation functions comprising the equations and functions which calculate the mechanical movement of trains and also which calculate the load flow of the electrical traction power supply system. In doing so this document provides all requirements necessary to demonstrate that a simulation tool may be used for the purposes of TSI approval of electric traction power supply systems. Any simulation tool which meets the acceptance requirements of the test cases in this document can be used to determine TSI compatibility for all systems of the same voltage and frequency without any requirement for further validation as part of the TSI assessment process. This document includes controls for the modification of simulation tools, in particular the limits of applicability of certification when tools are modified. These controls focus on determining whether the core functions of the simulation model are modified. This document provides only the requirements for demonstration of the algorithms and calculations of core functions. The use of a certified simulation tool in accordance with this document does not, in itself, demonstrate good practice in electric traction power supply system design, neither does it guarantee that the simulation models and data for infrastructure or trains used in the tool are correct for a given application. The choice and application of any models and data, of individual system components, in a design is therefore subject to additional verification processes and not in the Scope of this document. Competent development of design models and full understanding of the limits of design tools remain requirements in any system design. This document does not reduce any element of the need for competent designers to lead the design process. The test cases and data shown in Clause 6 in this document do not represent an existing network, but these data are used as theoretical/virtual network only for the purpose of verification of the core functionality. NOTE A new test case will be drafted considering metro, tramways and trolleybuses using DC 600 V or DC 750 V. Until this test case is available, this document can also be applied to subway, tram and trolley bus systems. This test case will also integrate rail systems using DC 750 V. Additionally, the application of this document ensures that the output data of different simulation tools are consistent when they are using the same set of input data listed in Clause 6. This document only applies to the simulation of electric traction power supply systems characteristics at their nominal frequency for AC or DC systems. It does not consider harmonic studies, electrical safety studies (e.g. rail potential), short circuit or electromagnetic compatibility studies over a wide frequency spectrum. This document does not mandate the use of a particular simulation tool in order to validate the design of an electric traction power supply system. This document does not consider complex models with active components such as static frequency convertors.
Bahnanwendungen - Ortsfeste Anlagen - Anforderungen an die Validierung von Simulationsprogrammen für die Auslegung von Bahnenergieversorgungssystemen
Applications ferroviaires - Installations fixes - Exigences relatives à la validation des outils de simulation utilisés pour la conception des réseaux d'alimentation de traction
Le présent document spécifie les exigences pour l'acceptation des outils de simulation utilisés pour évaluer la conception des réseaux d'alimentation électrique de traction conformément à la STI « Énergie ». Le présent document s'applique à la simulation des réseaux d'alimentation électrique de traction à courant continu et alternatif, dans le cadre de l'évaluation requise par la Directive (UE) 2016/797. Les méthodes et paramètres définis dans le présent document ne sont destinés qu'à être utilisés lors de la conception d'un réseau d'alimentation électrique de traction. Le présent document ne considère que la validation des outils au sein du sous-système STI Énergie pour tous les réseaux ferroviaires envisagés. Le présent document ne traite pas de la validation des outils de simulation par mesurage. Le présent document se concentre sur les fonctions de simulation clés comprenant les équations et fonctions qui calculent le mouvement mécanique des trains et qui calculent également les charges du réseau d'alimentation électrique de traction. De ce fait, le présent document fournit toutes les exigences nécessaires pour démonter qu'un outil de simulation peut être utilisé à des fins d'approbation STI des réseaux d'alimentation électrique de traction. Tout outil de simulation qui répond aux exigences d'acceptation des cas d'essai décrits dans le présent document peut être utilisé pour déterminer la compatibilité aux STI pour l'ensemble des réseaux de même tension et fréquence sans besoin d'une validation supplémentaire dans le cadre du processus d'évaluation STI. Le présent document inclut des contrôles pour la modification des outils de simulation, en particulier les limites de l'applicabilité de la certification lorsque les outils sont modifiés. Ces contrôles tâchent de déterminer si les fonctions clés du modèle de simulation sont modifiées. Le présent document fournit uniquement les exigences pour la démonstration des algorithmes et des calculs des fonctions clés. L'utilisation d'un outil de simulation certifié en conformité avec le présent document ne démontre pas, en elle-même, une meilleure pratique de conception d'un réseau d'alimentation électrique de traction, et ne garantit aucunement que les données et modèles de simulation pour les infrastructures et trains utilisés dans l'outil sont adaptées à une application spécifique. Le choix et l'application de toute donnée et de tout modèle, de composants systèmes individuels, dans une conception sont donc sujets à des processus de vérification supplémentaires non couverts par le présent document. Le développement compétent de modèles de conception et la compréhension complète des limites des outils de conception restent des exigences pour toute conception d'un système. Le présent document n'a pas pour vocation à limiter le besoin en concepteurs compétents pour piloter le processus de conception. Les cas d'essai et les données illustrés à l'Article 6 du présent document ne représentent aucunement un réseau existant, mais ces données sont utilisées comme un réseau théorique/virtuel uniquement aux fins de vérification des fonctionnalités clés. NOTE Un nouveau cas d'essai sera développé pour le métro, les tramways et les trolleybus fonctionnant sous un courant continu compris entre 600 V et 750 V. En attendant la diffusion de ce cas d'essai, le présent document peut être appliqué au métro, aux tramways et aux trolleybus. Ce cas d'essai intégrera également les systèmes ferroviaires fonctionnant avec un courant continu de 750 V. (...)

1 Scope
This document specifies requirements for the acceptance of simulation tools used for the assessment of
design of electric traction power supply systems with respect to TSI Energy.
This document is applicable to the simulation of AC and DC electric traction power supply systems, in the
frame of assessment required by Directive (EU) 2016/797. The methods and parameters defined in this
document are only intended for use in the design of the electric traction power supply system, and hence
this document solely considers validation of tools within the TSI energy subsystem for all envisaged railway
networks.
This document does not deal with validation of simulation tools by measurement.
This document focuses on the core simulation functions comprising the equations and functions which
calculate the mechanical movement of trains and also which calculate the load flow of the electrical traction
power supply system. In doing so this document provides all requirements necessary to demonstrate that
a simulation tool may be used for the purposes of TSI approval of electric traction power supply systems.
Any simulation tool which meets the acceptance requirements of the test cases in this document can be
used to determine TSI compatibility for all systems of the same voltage and frequency without any
requirement for further validation as part of the TSI assessment process.
This document includes controls for the modification of simulation tools, in particular the limits of applicability
of certification when tools are modified. These controls focus on determining whether the core functions of
the simulation model are modified.
This document provides only the requirements for demonstration of the algorithms and calculations of core
functions. The use of a certified simulation tool in accordance with this document does not, in itself,
demonstrate good practice in electric traction power supply system design, neither does it guarantee that
the simulation models and data for infrastructure or trains used in the tool are correct for a given application.
The choice and application of any models and data, of individual system components, in a design is
therefore subject to additional verification processes and not in the Scope of this document. Competent
development of design models and full understanding of the limits of design tools remain requirements in
any system design. This document does not reduce any element of the need for competent designers to
lead the design process.
The test cases and data shown in Clause 6 in this document do not represent an existing network, but
these data are used as theoretical/virtual network only for the purpose of verification of the core
functionality.
NOTE A new test case will be drafted considering metro, tramways and trolleybuses using DC 600 V or DC 750 V.
Until this test case is available, this document can also be applied to subway, tram and trolley bus systems. This test
case will also integrate rail systems using DC 750 V.
Additionally, the application of this document ensures that the output data of different simulation tools are
consistent when they are using the same set of input data listed in Clause 6.
This document only applies to the simulation of electric traction power supply systems characteristics at
their nominal frequency for AC or DC systems. It does not consider harmonic studies, electrical safety
studies (e.g. rail potential), short circuit or electromagnetic compatibility studies over a wide frequency
spectrum. This document does not mandate the use of a particular simulation tool in order to validate the
design of an electric traction power supply system.
This document does not consider complex models with active components such as static frequency
convertors.
