Railway applications - Rolling stock - Power supply with onboard energy storage system - Part 1: Series hybrid system

IEC 62864-1:2016 applies to series hybrid systems (electrically connected) with onboard energy storage (hereinafter referred as hybrid system). This standard specifies the following basic requirements, characteristics, functions and test methods for hybrid systems: - energy management to control the power flow among primary power source, energy storage system and power converters; - energy consumption, energy efficiency and regenerated energy; - vehicle characteristics achieved by energy storage system; - test methods of combined test; and - test methods of completed vehicles based on factory (stationary) and field (running) tests.

L'IEC 62864-1:2016 s'applique aux systèmes hybrides série (raccordés électriquement) équipés d'un système embarqué de stockage de l'énergie (ci-après dénommé le système hybride). La présente norme spécifie la liste suivante d'exigences fondamentales, de caractéristiques, de fonctions et de méthodes d'essai relatives aux systèmes hybrides: - la gestion de l'énergie afin de réguler le flux de puissance au sein de la source d'alimentation primaire, du système de stockage de l'énergie et des convertisseurs de puissance; - la consommation d'énergie, l'efficacité énergétique et l'énergie régénérée; - les caractéristiques du véhicule obtenues par le système de stockage de l'énergie; - les méthodes d'essai pour l'essai combiné; et - les méthodes d'essai des véhicules après achèvement selon des essais réalisés en usine (stationnaires) et sur le terrain (en marche).

Železniške naprave - Vozna sredstva - Napajanje s sistemom za shranjevanje energije na vozilu - 1. del: Serija hibridnega sistema

Ta del standarda IEC 62864 se uporablja za serijo hibridnih sistemov (galvansko povezanih) za shranjevanje energije na vozilu (v nadaljevanju: hibridni sistem).
Hibridni sistem ima dva (ali več) virov napajanja, vključno s sistemom za shranjevanje energije (EES) na vozilu, za doseganje naslednjih funkcij s kombinacijo pretvornika in motorjev ter izvajanjem kontrole upravljanja z energijo:
• izboljšanje energetske učinkovitosti in učinkovitosti porabe goriva, izboljšanje značilnosti pospeševanja, povečanje vozne razdalje in podaljšanje neprekinjenega obratovanja v primeru izgube primarnega vira napajanja (PPS) z uporabo sistema EES poleg primarnega vira napajanja pod pogoji, kjer sta moč in zmogljivost vira napajanja, vključno z regenerativno močjo, omejeni, ter posledično odpravljanje teh omejitev;
• zmanjšanje porabe goriva, zmanjšanje emisij (npr. CO2, NOx, trdnih delcev itd.);
• zmanjšanje okoljskih vplivov (npr. vidnih ovir, hrupa itd.).
Z razširitvijo so v tem standardu obravnavani tudi sistemi, ki imajo samo EES na vozilu brez drugih PPS.
Ta standard določa naslednje osnovne zahteve, značilnosti, funkcije in preskusne metode hibridnih sistemov:
• upravljanje z energijo za nadzor napajanja med primarnim virom napajanja, sistemom za shranjevanje energije in močnostnimi pretvorniki;
• poraba energije, energetska učinkovitost in regenerirana energija;
• značilnosti vozila zaradi sistema za shranjevanje energije;
• preskusne metode za kombinirane preskuse in
• preskusne metode za dokončana vozila na podlagi preskusov v tovarni (stacionarni) in na terenu (med obratovanjem).
OPOMBA: Pretvornik v tem standardu pomeni kombinirano opremo, ki je sestavljena iz enega ali več pretvornikov (npr. razsmernik, inverter, razsekalnik itd.).
Zajeti so vmesniki med naslednjimi viri napajanja:
• zunanje električno napajanje;
• sistemi za shranjevanje energije na vozilu (vključno s čistim shranjevanjem energije na vozilu);
• gorivne celice, dizelski električni generator in
• drugi viri napajanja.
Pri kombinaciji inverterjev in motorjev se ta standard uporablja za asinhronske ali sinhronske motorje, ki se napajajo prek inverterjev vira napetosti.
Sistemi virov napajanja ter kombinacije inverterjev in motorjev niso omejene na zgoraj navedeni seznam, temveč se lahko ta standard uporablja tudi za prihodnje sisteme.
Ta del standarda IEC 62864 zajema električno povezane sisteme (serijski hibrid) in ne sisteme, ki mehansko prenašajo pogonsko silo (vzporedni hibrid).

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62864-1 has been prepared by IEC technical committee 9:

Electrical equipment and systems for railways.
The text of this standard is based on the following documents:
FDIS Report on voting
