Validation of simulation of the dynamic interaction

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.
IEC 63453 has been prepared by IEC technical committee 9: Electrical equipment and systems for
railways . It is an International Standard,.

3 pantographs, as part of the predic�on of current collec�on quality. This document specifies func�onal
4 requirements for the valida�on of such simula�on tools to ensure confidence in, and mutual acceptance
5 of the results of the simula�ons.
6 This document deals with:
7 – input and output parameters of the simulation;
8 – comparison with line test measurements, and the characteristics of those line tests;
9 – validation of pantograph models;
10 – comparison between different simulation tools;
11 – limits of application of validated methods to assessments of pantographs and overhead contact lines.
12 This document applies to the current collec�on from an overhead contact line by pantographs mounted
13 on railway vehicles. It does not apply to trolley bus systems.

160 5 General
161 5.1 Overview of the validation process
162 The theore�cal study of the dynamic interac�on between pantograph and overhead contact line by
163 computer simula�on makes it possible to obtain much informa�on about the system and to minimize
164 the costs of line tests.
165 To be used with confidence the simula�on tool shall be validated. The valida�on for a simula�on tool
166 shall be done in a process described in Figure 1.
167 A simula�on tool validated according to this standard, shall be considered for applica�on to overhead
168 contact line/pantograph combina�ons and condi�ons only within the limits of validity defined in 10.3.
169 A new valida�on shall be made when the condi�ons to apply simula�on are outside the limita�ons
170 defined in 10.3 for exis�ng valida�ons.
171 The valida�on for a simula�on tool shall be done with the steps which are shown in Figure 1. The steps
172 are:
173 1) A first validation step shall be done by a “desktop assessment” in accordance to Clause 11. The most
174 relevant reference model data shall be chosen from the reference models in Annex A for the conditions
175 for which validation is required.
176 NOTE This desktop assessment will improve the confidence in the simulation tool. As Annex A cannot cover all
177 possible solutions and combinations a choice from this subset is necessary.
178 For validation of simulation tools implemented for new technologies in ways that are totally different
179 from the current state of the art, and which are not able to use models with the data according to
180 Annex A, the “desktop assessment” may be omitted.
181 NOTE Typically, all simulation tools for OCL from type “Flexible overhead contact line” according to IEC 60913 can use
182 models with data according to Annex A.
183 2) The final assessment shall be done by a “Line Test Data Validation” based on test results according
184 to 10.1 to demonstrate the accuracy of simulation according to 10.2.
185 Annex B provides data sets from line test measurements in accordance with IEC62846 to allow for a
186 validation for a given model within the limitations according to 10.3.
187 If the accuracy according to either 10.2 or to 11.4 cannot be achieved, then the simula�on tool shall be
188 improved according to 6.3 for pantograph model adjustments and according to 7.3 for overhead contact
189 line model before revalida�on.
