Railway applications - Energy measurement on board trains - Part 2: Energy measuring

This draft European Standard covers the requirements applicable to the Energy Measurement Function (EMF) of an Energy Measurement System (EMS) for use on board traction units for measurement of energy supplied directly from/to the Contact Line system.
This draft European Standard also gives requirements for the Current Measurement Function (e.g. current sensor), the Voltage Measurement Function (e.g. voltage sensor) and the Energy Calculation Function (e.g. energy meter).
The Conformity Assessment arrangements for the Voltage Measurement Function, Current Measurement Function, the Energy Calculation Function and a complete Energy Measurement Function are also specified in this document.
The standard has been developed taking into account that in some applications the EMF may be subjected to legal metrological control. All relevant metrological aspects are covered in this part.
Figure 2 shows the flow between the functional blocks of the EMF. Only connections between the functional blocks required by this standard are displayed.

La présente Norme européenne couvre les exigences applicables à la fonction de mesure d’énergie (EMF) d’un système de mesure d’énergie (EMS) à utiliser à bord des unités de traction pour mesurer l’énergie directement récupérée au niveau du système de ligne de contact ou envoyée à ce dernier.
La présente Norme européenne spécifie également les exigences pour la fonction de mesure de courant (par exemple, capteur de courant), la fonction de mesure de tension (par exemple, capteur de tension) et la fonction de calcul d'énergie (par exemple, compteur d'énergie).
Les dispositions relatives à l'évaluation de la conformité pour la fonction de mesure de tension, la fonction de mesure de courant, la fonction de calcul d'énergie et l'ensemble d'une fonction de mesure d'énergie sont également spécifiées dans ce document.
Cette norme a été élaborée en tenant compte du fait que, dans certaines applications, l'EMF peut être soumise à un contrôle métrologique réglementaire. Toutes les caractéristiques métrologiques pertinentes sont traitées dans la présente partie.

EN 50463-2:2017 (E)
Introduction

The Energy Measurement System provides measurement and data suitable for billing and may also

be used for energy management, e.g. energy saving.

This series of European Standards uses the functional approach to describe the Energy Measurement

System and on-ground Data Collecting System. These functions are implemented in one or more

physical devices. The user of this series of standards is free to choose the physical implementation

arrangements.
a) Structure and main contents of the EN 50463 series:

This series of European Standards is divided into five parts. The titles and brief descriptions of

each part are given below:
1) EN 50463-1 — General:
The scope of EN 50463-1 is the Energy Measurement System (EMS).
EN 50463-1 provides system level requirements for the complete EMS and common
requirements for all devices implementing one or more functions of the EMS.
2) EN 50463-2 — Energy measuring:
The scope of EN 50463-2 is the Energy Measurement Function (EMF).
The EMF provides measurement of the consumed and regenerated active energy of a

traction unit. If the traction unit is designed for use on AC traction systems, the EMF also

provides measurement of reactive energy. The EMF provides the measured quantities via an

interface to the Data Handling System.
The EMF consists of the three functions: Voltage Measurement Function, Current

Measurement Function and Energy Calculation Function. For each of these functions,

accuracy classes are specified and associated reference conditions are defined. This part

also defines all specific requirements for all functions of the EMF.

The Voltage Measurement Function measures the voltage of the Contact Line system and

the Current Measurement Function measures the current taken from and returned to the

Contact Line system. These functions provide signal inputs to the Energy Calculation

Function.
The Energy Calculation Function inputs the signals from the Current and Voltage

Measurement Functions and calculates a set of values representing the consumed and

regenerated energies. These values are transferred to the Data Handling System and are

used in the creation of Compiled Energy Billing Data (CEBD).

The standard has been developed taking into account that in some applications, the EMF

may be subjected to legal metrological control. All relevant metrological aspects are covered

in this part of EN 50463.
EN 50463-2 also defines the conformity assessment of the EMF.
3) EN 50463-3 — Data handling:
The scope of EN 50463-3 is the Data Handling System (DHS) and the associated
requirements of Data Collecting System (DCS).
---------------------- Page: 10 ----------------------
SIST EN 50463-2:2018
EN 50463-2:2017 (E)

The on board DHS receives, produces and stores data, ready for transmission to any

authorized receiver of data on board or on ground. The main goal of the DHS is to produce

Compiled Energy Billing Data and transfer it on an interoperable basis to an on-ground Data

Collecting System (DCS). The DHS can support other functionality on board or on-ground

with data, as long as this does not conflict with the main goal.

The DCS on-ground receives Compiled Energy Billing Data and transfer it to settlement

system.

EN 50463-3 also defines the conformity assessment of the DHS and for the transfer of CEBD

to an on-ground Data Collecting System (DCS).
4) EN 50463-4 — Communication:
The scope of EN 50463-4 is the communication services.

This part of EN 50463 gives requirements and guidance regarding the data communication

between the functions implemented within EMS as well as between such functions and other

on board units where data are exchanged using a communications protocol stack over a

dedicated physical interface or a shared network.

It includes the reference to the on board to ground communication service and covers the

requirements necessary to support data transfer between DHS and DCS including the

transfer of CEBD on an interoperable basis.

EN 50463-4 also defines the conformity assessment of the communications services.

5) EN 50463-5 — Conformity assessment:
The scope of EN 50463-5 is the conformity assessment procedures for the EMS.

EN 50463-5 also covers re-verification procedures and conformity assessment in the event of

the replacement of a device of the EMS.
b) EMS functional structure and dataflow:

Figure 1 illustrates the functional structure of the EMS, the main sub-functions and the structure of

the dataflow and is informative only. Only the main interfaces required by this standard are

displayed by arrows.

Since the communication function is distributed throughout the EMS, it has been widely omitted

for clarity, except for the train to ground communication. Not all interfaces are shown.

1 Scope

This European Standard covers the requirements applicable to the Energy Measurement Function

(EMF) of an Energy Measurement System (EMS) for use on board traction units for measurement of

energy supplied directly from/to the Contact Line system.

This European Standard also gives requirements for the Current Measurement Function (e.g. current

sensor), the Voltage Measurement Function (e.g. voltage sensor) and the Energy Calculation Function

(e.g. energy meter).

The Conformity Assessment arrangements for the Voltage Measurement Function, Current

Measurement Function, the Energy Calculation Function and a complete Energy Measurement

Function are also specified in this document.

The standard has been developed taking into account that in some applications the EMF can be

subjected to legal metrological control. All relevant metrological aspects are covered in this part.

Figure 2 shows the flow between the functional blocks of the EMF. Only connections between the

functional blocks required by this standard are displayed.
