2. DESCRIPTION OF THE ENERGY SUBSYSTEM

2.1. Definition

(1) This TSI covers all fixed installations necessary to achieve interoperability that are required to supply traction energy to a train.

(2) The energy subsystem consists of: (a) substations: connected on the primary side to the high-voltage grid, with transformation of the high-voltage to a voltage and/or conversion to a power supply system suitable for the trains. On the secondary side, substations are connected to the railway contact line system; (b) sectioning locations: electrical equipment located at intermediate locations between substations to supply and parallel contact lines and to provide protection, isolation and auxiliary supplies; (c) separation sections: equipment required to provide the transition between electrically different systems or between different phases of the same electrical system; (d) contact line system: a system that distributes the electrical energy to the trains running on the route and transmits it to the trains by means of current collectors. The contact line system is also equipped with manually or remotely controlled disconnectors which are required to isolate sections or groups of the contact line system according to operational necessity. Feeder lines are also part of the contact line system; (e) return circuit: all conductors which form the intended path for the traction return current. Therefore, so far as this aspect is concerned, the return circuit is part of the energy subsystem and has an interface with the infrastructure subsystem.

2.1.2. Geometry of the overhead contact line (OCL) and quality of current collection

(1) The objective is to ensure reliable and continuous power transfer from the power supply system to the rolling stock. The interaction between the overhead contact line and the pantograph is an important aspect of interoperability.

(2) Basic parameters referring to the geometry of the OCL and quality of current collection are set out in point 4.2.

4. CHARACTERISATION OF THE SUBSYSTEM

4.1. Introduction

(1) The whole rail system, to which Directive 2008/57/EC applies and of which the energy subsystem is a part, is an integrated system whose consistency needs to be verified. This consistency must be checked, in particular, with regard to the specifications of the energy subsystem, its interfaces vis-à-vis the system in which it is integrated, as well as the operating and maintenance rules. The functional and technical specifications of the subsystem and its interfaces, described in points 4.2 and 4.3, do not impose the use of specific technologies or technical solutions, except where this is strictly necessary for the interoperability of the rail network.

(2) Innovative solutions for interoperability, which do not fulfil requirements specified in this TSI and are not assessable as stated in this TSI, require new specifications and/or new assessment methods. In order to allow technological innovation, these specifications and assessment methods shall be developed by the process for innovative solutions described in points 6.1.3 and 6.2.3.

(3) Taking account of all the applicable essential requirements, the energy subsystem is characterised by the specifications set out in points 4.2 to 4.7.

4.2.10. Pantograph gauge

(1) No part of the energy sub-system shall enter the mechanical kinematic pantograph gauge (see Appendix D figure D.2) except for the contact wire and steady arm.

(2) The mechanical kinematic pantograph gauge for interoperable lines is specified using the method shown in Appendix D.1.2 and the pantograph profiles defined in LOC&PAS TSI, points 4.2.8.2.9.2.1 and 4.2.8.2.9.2.2.

(2) S0 is the calculated, simulated or measured uplift of the contact wire at a steady arm, generated in normal operating conditions with one or more pantographs with the upper limit of Fm at the maximum line speed. When the uplift of the steady arm is physically limited due to the overhead contact line design, it is permissible for the necessary space to be reduced to 1,5S0 (refer to EN 50119:2009, clause 5.10.2).

(3) Maximum force (Fmax) is usually within the range of Fm plus three standard deviations σmax; higher values may occur at particular locations and are given in EN 50119:2009, table 4, clause 5.2.5.2.

4.2.15.2. Lines with speed v ≥ 250 km/h

Two types of designs of phase separation sections may be adopted, either:

(a) a phase separation design where all the pantographs of the longest TSI compliant trains are within the neutral section. The overall length of the neutral section shall be at least 402 m. For detailed requirements see EN 50367:2012, Annex A.1.2, or

(b) a shorter phase separation with three insulated overlaps as shown in EN 50367:2012, Annex A.1.4. The overall length of the neutral section is less than 142 m including clearances and tolerances.

4.2.15.3. Lines with speed v < 250 km/h

The design of separation sections shall normally adopt solutions as described in EN 50367:2012, Annex A.1. Where an alternative solution is proposed, it shall be demonstrated that the alternative is at least as reliable.

4.2.16. System separation sections

4.2.16.1. General

(1) The design of system separation sections shall ensure that trains can move from one power supply system to an adjacent different power supply system without bridging the two systems.

(2) The neighbouring Infrastructure Managers shall agree either (a) or (b) according to the prevailing circumstances.

(3) The overall length D of neutral sections is defined in EN 50367:2012, clause 4. For the calculation of D clearances in accordance to EN 50119:2009, clause 5.1.3 and an uplift of S0 shall be taken into account.

4.2.16.2. Pantographs raised

(1) Power consumption of the train (traction, auxiliaries and no-load current of the transformer) shall be brought to zero before entering the system separation section.

(2) If system separation sections are traversed with pantographs raised to the contact wire, their functional design is specified as follows: (a) the geometry of different elements of the overhead contact line shall prevent pantographs short-circuiting or bridging both power systems; (b) provision shall be made in the energy subsystem to avoid bridging of both adjacent power supply systems should the opening of the on-board circuit breaker(s) fail; (c) variation in contact wire height along the entire separation section shall fulfil requirements set in EN 50119:2009, clause 5.10.3.

4.2.16.3. Pantographs lowered

(1) This option shall be chosen if the conditions of operation with pantographs raised cannot be met.

(2) If a system separation section is traversed with pantographs lowered, it shall be designed so as to avoid the electrical connection of the two power supply systems by an unintentionally raised pantograph.

4.2.17. On-ground energy data collecting system

(1) Point 4.2.8.2.8 of LOC & PAS TSI contains the requirements for on-board Energy Measuring Systems (EMS) intended to produce and transmit the Compiled Energy Billing Data (CEBD) to an on-ground energy data collecting system.

(3) The specification related to interface protocols between EMS and DCS and transferred data format are an open point, which, in any case, shall be closed within 2 years after the entry into force of this Regulation.

4.2.18. Protective provisions against electric shock

Electrical safety of the overhead contact line system and protection against electric shock shall be achieved by compliance with EN 50122-1:2011+A1:2011, clauses 5.2.1 (only for public areas), 5.3.1, 5.3.2, 6.1, 6.2 (excluding requirements for connections for track circuits) and regarding AC voltage limits for the safety of persons by compliance with 9.2.2.1 and 9.2.2.2 of the standard and regarding DC voltage limits by compliance with 9.3.2.1 and 9.3.2.2 of the standard.
