Železniške naprave - Vozna sredstva - Kombinirano preskušanje motorjev in njihovega krmiljenja
Ta mednarodni standard se uporablja za vlečni sistem, sestavljen (kadar je ustrezno) iz vlečnih motorjev, opreme za nadzor vleke, vključno s programsko opremo, transformatorjev, vhodnih filtrov, zavornih uporov, glavnih odklopnikov, opreme za hlajenje, pretvornikov, stikal itd.
Tokovni odjemnik, mehanski zavorni sistemi in menjalnik so zunaj področja uporabe tega
standarda.
Vrste motorjev, za katere se uporablja ta standard, so asinhroni motorji ali sinhroni motorji s trajnim magnetom (PMM) ali motorji na enosmerni tok (DC).
Pomožni pretvorniki so zajeti, kadar je pomožni pretvornik zaprt v vlečnem pretvorniku. Kadar sicer vlečni sistem napaja pomožni sistem izven vlečnega pretvornika, se lahko pomožni sistem zamenja z enako obremenitvijo. OPOMBA 1: Sistem za shranjevanje električne energije ni zajet v tem standardu, ker ni specifičnega standarda za tipski preskus sistema za shranjevanje električne energije.
OPOMBA 2: Preverjanje pomožnih obremenitev ni del tega standarda.
OPOMBA 3: Menjalnik je lahko del priprave preskusa, vendar ni del vlečnega sistema.
Cilj tega standarda je določiti tipski preskus za vlečni sistem, ki je sestavljen predvsem iz:
– preskusa lastnosti;
– preskusnih metod za preverjanje teh lastnosti.
Ta standard ne določa tipskega preskusa za vsako posamezno komponento.
Preskušani vlečni sistem vključuje vsaj eno celotno linijo za pretvarjanje vleke (vsaj en vlečni pretvornik in ustrezne obremenitve, en transformator v primeru napajanja z izmeničnim tokom ali vhodni filter v primeru napajanja z enosmernim tokom). Reprezentativnost preskušanega vlečnega sistema v primerjavi z dejanskim vlečnim sistemom je dogovorjena med uporabnikom in proizvajalcem.
Preskušani vlečni sistem je opremljen z dvema komponentama, ki sta reprezentativni za proizvodno serijo.
Odstopanja so dovoljena na podlagi dogovora med uporabnikom in proizvajalcem ter so utemeljena na podlagi stališč pred preskusom. Uporaba enakih komponent ali delov je dovoljena, če ni pričakovanih večjih vplivov na rezultate preskusa.

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.

COMBINED TEST METHOD FOR TRACTION SYSTEMS
1 Scope
This International Standard applies to the traction system consisting (when it applies) of
traction motor(s), converter(s), traction control equipment including software, transformer,
input filters, brake resistors, main circuit-breaker, cooling equipment, transducers, contactors,
etc.
Figure 1 is just an overview and is not representative of all traction system architectures.
Current collector, mechanical braking systems and gearbox are not in the scope of this
standard.
Types of motors applicable in this standard are asynchronous, or synchronous including
permanent magnet (PMM), or direct current (DC).
The auxiliary converter(s) is (are) part of the scope when the auxiliary converter is enclosed
within the traction converter. Otherwise, when the traction system feeds an auxiliary system
outside the traction converter, the auxiliary system can be replaced by an equivalent load.
NOTE 1 Energy storage system is not considered in this standard since there is no specific type test standard for
energy storage system.
NOTE 2 Auxiliary loads validation is not part of this standard.
NOTE 3 The gearbox can be part of test set-up, but it is not a part of traction system.

The objective of this standard is to specify the type test of a traction system, mainly
comprising of:
– test of performance characteristics;
– test methods of verifying these performance characteristics.
This standard does not specify the type test of each individual component.
The traction system under test incorporates at least one complete traction conversion line (at
least one traction converter and its related loads, one transformer in the case of AC supply or
input filter in the case of DC supply). The representativeness of the traction system under test
versus the actual traction system is agreed between the user and manufacturer.
Figure 2 gives one example of the relationship between the traction system under test and the
whole traction system.

and the “traction system”
The traction system under test is equipped with components that are representative of the
production series.
Deviations may be permitted by agreement between user and manufacturer, and are justified
from an impact stand point in advance of the test. Using equivalent components or parts is
permitted if no significant influence on the test result is expected.

test that is not mandatory and subject to agreement between the user and manufacturer
4 Traction system characteristics
Traction system specifications shall, as a general rule, include characteristic curves. These
curves are defined as the specified characteristics. They shall be plotted to the designed
operating limits of each variable. They shall generally be drawn for the AC or DC supply
voltage of the traction system at its specified nominal value. They may also be drawn for the
lower and higher voltage of the supply of the traction system if agreed between the user and
manufacturer.
These characteristics shall be drawn for a reference temperature of the motor (winding or
magnet) and the design temperature of the parts of the converter, transformer and line filter,
etc., expected by the supplier.
The reference temperature of the motor (winding or magnet) shall be according to the values
as in IEC 60349 series or subject to agreement between the user and manufacturer.
The following characteristics are defined:
IEC 61377:2016 © IEC 2016 – 13 –
a) Specified characteristics: values defined in order to fulfil the user contractual
requirements. They are the reference values for measurement and shall be validated on
the test bench.
b) Internal characteristics: internal design values which shall be measured and used to
prove the design but do not have an influence on the acceptance of the combined test,
such as root-mean-square value of current/voltage of traction motor for example.
Provided that the measurement results are compliant with the specified characteristics, the
test results remain valid, even if the internal characteristics are not exactly the same as the
ones specified. The difference should be agreed between the user and manufacturer.
The set of specified characteristics on fixed operating points over the speed-torque curve, at
given line voltages (according to IEC 60850 or otherwise specified if outside the scope of
IEC 60850) and given wheel diameter is:
• torque versus speed;
• efficiency of the traction system versus speed at maximum torque reference along the
curve.
Specified and internal characteristics can be measured during a speed sweep test or a test at
constant speed .
NOTE 1 In the case of speed sweep the inertia mass of the motor rotor considerably influences measurement of
the motor shaft torque.
The set of specified characteristics on the route profile at a specific line voltage is:
• torque reference value and speed versus time at the given wheel diameter;
• line current and voltage;
• all relevant peak temperatures (see Figure 4);
• input electrical energy consumption in kWh (integrated value over entire route profile).
NOTE 2 Specified and internal characteristics except those listed above are described in the following clauses for
each test.
