This document specifies the requirements and test methods for a stationary energy storage
system to be introduced as a trackside installation and used in a power supply network of a
DC electrified railway. This system can take electrical energy from the DC power supply
network, store the energy, and supply the energy back to the DC power supply network when
necessary. This document does not apply to onboard energy storage systems.
This document applies to systems which are installed to achieve one or more of the following
objectives.
• Absorption of regenerative energy:
– effective use of regenerative energy (saving energy);
– reduction of rolling stock maintenance (reduction of brake shoe/pad wear, etc.);
– avoidance of adverse effects of heat generated during braking (e.g. in tunnels, etc.).
• Power compensation:
– compensation of line voltage;
– reduction of peak power;
– reduction in the requirement of the rectifier ratings.
If this system is combined with one or more of the following functions, this document may be
used as a guideline:
• reverse transmission of regenerated power to the upstream power supply network
(e.g. inverting or reversible substations);
• use of the regenerated energy for purposes other than the running of trains, such as for
station facilities, etc.;
• resistive consumption of regenerated power.
Although it is assumed that the system uses the following typical energy storage technologies,
this document also applies to other existing or future technologies:

Ta dokument določa zahteve in preskusne metode za nepremični sistem za shranjevanje energije, ki bo nameščen ob progi in se bo uporabljal v električnem omrežju enosmerno elektrificirane železnice. Sistem lahko pridobi električno energijo iz enosmernega električnega omrežja, jo shrani in dovaja nazaj v enosmerno električno omrežje, ko je to potrebno. Ta dokument se ne uporablja za sisteme za shranjevanje energije na vozilu.
Ta dokument se uporablja za sisteme, ki se montirajo, da se doseže eden ali več naslednjih ciljev.
• Absorpcija regenerativne energije:
– učinkovita uporaba regenerativne energije (prihranek energije);
– zmanjšanje vzdrževanja voznega parka (manjša obraba zavornih čeljusti/oblog itd.);
– preprečevanje negativnih vplivov toplote, ki nastaja med zaviranjem (npr. v tunelih itd.).
• Kompenzacija moči:
– kompenzacija omrežne napetosti;
– zmanjšanje največje moči;
– zmanjšanje zahtev glede nazivnih vrednosti usmernikov.
Če je sistem kombiniran z eno ali več naslednjimi funkcijami, se lahko ta dokument uporablja kot vodilo:
• povratni prenos regenerativne moči v visokonapetostno stran električnega omrežja (npr. inverterske ali reverzibilne postaje);
• uporaba regenerativne energije za namene, ki ne zajemajo obratovanja vlakov, npr. za postajno infrastrukturo itd.;
• uporna poraba regenerativne moči.
Čeprav se predpostavlja, da sistem uporablja naslednje tipične tehnologije za shranjevanje energije, se ta dokument uporablja tudi za druge obstoječe ali bodoče tehnologije:
• akumulatorji (litij-ionski, nikelj-kovinski hidridni itd.);

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 62924 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:

INTRODUCTION
To save natural resources and counteract global warming, techniques to save energy and/or
to improve environmental characteristics are drawing strong interest. In the railway industry,
electric rail vehicles fitted with regenerative braking systems have been introduced, not only
to save energy, but also to ease maintenance and to reduce the adverse effects of heat
generated during braking (especially in tunnels).
However, in DC electric railways, when a train regenerates power, usually the power has to
be consumed within the DC network, because DC power supply substations are usually not
reversible. There is no guarantee that adequate load exists for regenerative braking trains; in
such a circumstance, regenerative braking becomes ineffective, either in part or in whole. In
this situation, the power supply network is unreceptive. Among the emerging technologies to
improve receptivity is stationary energy storage systems (ESSs). A stationary ESS charges
regenerative energy when the power supply network is unreceptive and stores it for use at a
later time.
International Standards for stationary ESSs have not been issued. Before ESSs become
widely used, international standardization of the basic system structure and measurement
method for efficiency, etc., will serve as a guideline for users and manufacturers who want to
introduce ESSs.
