EN 50463-1:2017 (E) 5 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 Collection Service. 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 railway 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. EN 50463-2 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 EN 50463-2. 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). The on board DHS receives, produces and stores data, ready for transmission to any authorized receiver of data onboard or on ground. The main goal of the DHS is to produce Compiled Energy Billing Data (CEBD) and transfer it to an on ground Data Collecting System (DCS). The DHS can SIST EN 50463-1:2018
EN 50463-1:2017 (E) 6 support other functionality on board or on ground with data (e.g. for energy management, driver advisory systems, etc.), 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.

Subclause 4.2 gives system level requirements for the complete EMS. Subclause 4.3 gives common requirements for all devices implementing one or more functions of the EMS. 4.2 System level requirements 4.2.1 General If an EMS has any functions which are additional to those specified in the EN 50463 series, then these functions shall not: • affect the accuracy, • degrade the operation of the EMS, and • influence the production and storage of CEBD and CEBD-related data. Any changes to configuration shall be logged in the EMS, and the device marking and stored information shall also be updated. 4.2.2 Accuracy The energy measurement accuracy is defined by the functions of the EMF and shall be determined in accordance with EN 50463-2. 4.2.3 EMS operation and power supply 4.2.3.1 General The EMS shall be fully operational whenever energy flows from or to the CL. Any part of the EMS powered by an auxiliary power supply shall be compatible with the requirements of EN 50155 regarding power supply characteristics. The rated power supply voltage and maximum power consumption of the EMS shall be stated. 4.2.3.2 Power-up The EMS shall achieve operational status and be ready to measure energy within 60 s after application of power to the EMS. NOTE 1 The application of power to the EMS is an installation design consideration. NOTE 2 The 60 s maximum time limit has been selected because the power-up procedure for traction units typically requires several minutes to elapse between switching on the vehicles ancillary supplies and any significant amount of energy being drawn from the CL. SIST EN 50463-1:2018
EN 50463-1:2017 (E) 14 4.2.3.3 Power-down In the event of intentional loss of power to the EMS, no CEBD and other data shall be lost. Unintentional loss of power shall not affect data stored in the EMS. NOTE The EMS could include a procedure for transmitting all unsent CEBD to DCS as part of a planned power-down procedure of the EMS. This can help to support timely data processing on-ground. 4.2.4 EMS measuring input 4.2.4.1 Installation point of the VMF and CMF The position of the VMF(s) and CMF(s) in the power circuit shall ensure that all active and reactive energy taken from and returned to the CL is measured. NOTE
Devices consuming small quantities of energy (e.g. high impedance voltage monitoring/detection devices, insulators, etc.) are not considered significant and their consumption need not be measured by the EMS. 4.2.4.2 Characteristics of traction system The ratings of the EMS voltage and current measuring inputs shall be selected in accordance with EN 50463-2 taking into account the intended traction system and traction unit rated current. 4.2.5 Data handling 4.2.5.1 Traction system change An EMS (one or multiple) shall cover all traction systems that the traction unit can operate on. If an EMS is used for more than one traction system, it shall continue to function correctly when changing between systems, and log each change of traction system. Changes between 600 V and 750 V DC. traction systems do not need to be logged. NOTE 1 This can be achieved directly by the EMS or by input signals from the traction unit. NOTE 2 If voltage detection is used to detect traction system change, overvoltages above Umax2, in accordance with EN 50163, and voltage drops below Umin2 could cause a detection of a system change. The EMS shall measure energy consumption within 1 s of the change to the new traction system. 4.2.5.2 Consumption Point Identification Each EMS shall be assigned a unique consumption point Identification.(CPID). The CPID is composed by the content of the following fields: • NVR - National Vehicle Register code; • VKM - Vehicle Keeper Marking; • EVN - European Vehicle Number/OTIF Number; • EMSID – Energy Measurement System ID. When presented as a string, the CPID shall be composed according to the following scheme: [NVR]_[VKM]_[EVN][EMSID] The brackets are for convenience only, the following example illustrates this: D_DB_9180540618421. The CPID shall be stored in non-volatile memory of the EMS. Security procedures shall be implemented to prevent unauthorized changes to the CPID. SIST EN 50463-1:2018
EN 50463-1:2017 (E) 15 NOTE 1 Where the EMS is set up to produce CEBD that includes parallel readings of same type energy values, the energy data will be put in channels in the data transfer of CEBD from EMS to DCS and each channel will be uniquely identified by a ChannelD in the transfer file. See EN 50463–4 for details. NOTE 2 CPID was defined in EN 50463–1:2012 as a 13 digit number (numeric value without dividers or decimals) based on a European Vehicle Number from the traction unit plus one additional digit to uniquely identifying each EMS installed on the traction unit. NOTE 3 The EMS can carry a fictitious CPID until such time as the EMS is commissioned into commercial use. The process of assigning the correct CPID to a specific EMS needed when bringing it into commercial use is out of the scope of this standard. 4.2.6 RAMS 4.2.6.1 Reliability Reliability requirements shall be in accordance with EN 50155:2017, 6.1.1. Reliability figures and calculation methods are a matter of agreement between the supplier and purchaser. 4.2.6.2 Ava
