Railway Applications - Power supply and rolling stock - Technical criteria for the coordination between power supply (substation) and rolling stock to achieve interoperability

This European Standard establishes requirements for the compatibility of rolling stock with infrastructure particularly in relation to: – co-ordination of protection principles between power supply and traction units, especially fault discrimination for short-circuits; – co-ordination of installed power on the line and the power demand of trains; – co-ordination of traction unit regenerative braking and power supply receptivity; – co-ordination of harmonic behaviour. This European Standard deals with the definition and quality requirements of the power supply at the interface between traction units and fixed installations. This European Standard specifies the interface between rolling stock and electrical fixed installations for traction, in respect of the power supply system. The interaction between pantograph and overhead contact line is dealt with in EN 50367. The interaction with the “control-command” subsystem (especially signalling) is not dealt with in this standard. Requirements are given for TSI lines (both high speed and conventional) and classical lines. For classical lines, values, where given, are for the existing European networks. Furthermore the maximum values that are specified are applicable to the foreseen developments of the infrastructure of the Trans European rail networks. 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. This European Standard does not apply retrospectively to rolling stock already in service. Information is given on electrification parameters such as to enable train operating companies to confirm, after consultation with the rolling stock manufacturers, that there will be no consequential disturbance on the electrification system.

Železniške naprave - Preskrba z električno energijo in vozna sredstva - Tehnična merila za uskladitev med elektronapajalnimi postajami in elektrovlečnimi vozili za doseganje medobratovalnosti

Ta evropski standard določa zahteve za združljivost voznih sredstev z infrastrukturo, zlasti v zvezi z: – uskladitvijo varnostnih načel za elektronapajalne postaje in vlečna vozila, zlasti glede razlikovanja napake kratkega stika; – uskladitvijo napeljane električne energije na progi in odjemne moči vlakov; – uskladitvijo regenerativnega zaviranja vlečnega vozila in zmogljivosti napajanja; – uskladitvijo harmoničnega delovanja. Ta evropski standard obravnava definicijo in zahteve glede kakovosti za preskrbo z električno energijo na vmesnikih med vlečnimi vozili in nepremičnimi napravami. Ta evropski standard določa vmesnik med voznimi sredstvi in električnimi nepremičnimi napravami za vleko, kar zadeva sistem preskrbe z električno energijo. Interakcija med odjemnikom toka in kontaktnim vodnikom je obravnavana v standardu EN 50367. Interakcija s podsistemom »upravljanja-vodenja« (zlasti signalizacijo) ni obravnavana v tem standardu. Navedene so zahteve za proge, skladne s tehničnimi specifikacijami za interoperabilnost (TSI) (za visoke in konvencionalne hitrosti), ter za običajne proge. Če so vrednosti za običajne proge navedene, so to vrednosti za obstoječa evropska omrežja. Poleg tega se navedene največje vrednosti uporabljajo za predviden razvoj infrastrukture vseevropskih železniških omrežij. Področje uporabe zajema naslednje električne vlečne sisteme: – železnice; – vodene sisteme javnega prevoza, ki so integrirani z železnicami; – sisteme prevoza blaga, ki so integrirani z železnicami. Ta evropski standard se ne uporablja retrospektivno za vozna sredstva, ki so že v obratovanju. Navedene so informacije o elektrifikacijskih parametrih, na podlagi katerih se družbam za opravljanje železniških prevozov omogoči, da po posvetovanju s proizvajalci voznih sredstev potrdijo, da ne bo bistvenih motenj na elektrifikacijskem sistemu.

1 Scope

This European Standard establishes requirements for the compatibility of rolling stock with infrastructure

particularly in relation to:

– co-ordination of protection principles between power supply and traction units, especially fault

discrimination for short-circuits;
– co-ordination of installed power on the line and the power demand of trains;

– co-ordination of traction unit regenerative braking and power supply receptivity;

– co-ordination of harmonic behaviour.

This European Standard deals with the definition and quality requirements of the power supply at the

interface between traction units and fixed installations.

This European Standard specifies the interface between rolling stock and electrical fixed installations for

traction, in respect of the power supply system. The interaction between pantograph and overhead contact

line is dealt with in EN 50367. The interaction with the “control-command” subsystem (especially signalling)

is not dealt with in this standard.

Requirements are given for TSI lines (both high speed and conventional) and classical lines.

For classical lines, values, where given, are for the existing European networks. Furthermore the maximum

values that are specified are applicable to the foreseen developments of the infrastructure of the Trans

European rail networks.
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.

This European Standard does not apply retrospectively to rolling stock already in service.

Information is given on electrification parameters such as to enable train operating companies to confirm,

after consultation with the rolling stock manufacturers, that there will be no consequential disturbance on the

electrification system.

5 Separation sections
5.1 Phase separation sections

Trains shall be able to move from one section of an a.c. system to an adjacent section of the same system,

through a phase separation section, without bridging the different phases.

Power consumption of the train (traction, auxiliaries and no-load current of the transformer) shall be brought

to zero before entering the phase separation section.
For HS TSI lines, this shall be done automatically.

For Conventional Rail TSI lines and for classical lines, where required by the infrastructure manager this

shall be done automatically. Otherwise, automatic operation is preferred, but manual on board operation may

also be employed.

Where particular circumstances require the lowering of the pantographs this shall be recorded in the register

of infrastructure.

For phase separation sections longer than 8 m, the infrastructure manager shall provide adequate means to

allow a train that is gapped underneath the phase separation to be restarted.

EN 50367 describes the characteristics of some designs of phase separation sections.

NOTE For other designs of phase separation that allow trains to pass the section with power running (e.g. automatically switched

sections or “change over sections”), the requirements of this clause may not apply if reliability and compatibility with all trains can be

demonstrated.
5.2 System separation sections
5.2.1 General

Trains shall be able to move from one energy supply system to an adjacent one which uses a different

energy supply without bridging the two contact line systems. The necessary actions (opening of the main

circuit breaker, lowering of the pantographs, etc.) depend on the type of both supply systems as well as on

the arrangement of pantographs on trains and the running speed.

There are two possibilities for trains to run through system separation sections:

1) with pantograph raised and touching the co
