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 60034-16-1 has been prepared by IEC technical committee 2:
Rotating machinery.
This second edition cancels and replaces the first edition, issued in 1991, and constitutes a
technical revision.
The major technical changes with regard to the previous edition are as follows:

ROTATING ELECTRICAL MACHINES –

Part 16-1: Excitation systems for synchronous machines –
Definitions
1 Scope
This part of IEC 60034 defines terms applicable to the excitation systems of synchronous
rotating electrical machines.
2 General
2.1
excitation system
equipment providing the field current of a machine, including all regulating and control
elements, as well as field discharge or suppression equipment and protective devices
2.1.1
digital excitation system
excitation system of a machine where some, if not all, of regulating, control, limiting and
protective functionality is implemented using digital technology
NOTE As a minimum, the voltage regulation function must be implemented digitally in such a system.
2.1.2
reversible excitation system
excitation system providing compulsory change of sign of magnetic flux, created by a winding
or excitation windings of a synchronous machine
2.2
exciter
source of the electrical power, providing field voltage and current of a synchronous machine,
regulated by excitation control
NOTE Examples of the source are:
a rotating machine, either d.c. or a.c. with associated rectifiers;
one or several transformers with associated rectifiers.
2.3
excitation control
control of excitation system modifying the excitation power, responding to signals
characteristic of the state of the system encompassing the synchronous machine, its exciter,
and the network to which it is connected
NOTE Synchronous machine voltage is predominantly the controlled quantity.
2.4
excitation control system
feedback control system that includes the synchronous machine operating in the power
system and its excitation system
NOTE 1 The term is used to distinguish the performance of the synchronous machine and excitation system in
closed loop control conjunction with the power system from that of the excitation system alone.
