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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC 61968-2, which is a technical specification, has been prepared by IEC technical
committee 57: Power system control and associated communications.

Full information on the voting for the approval of this technical specification can be found in
the report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 61968 consists of the following parts under the general title Application integration at
electric utilities – System interfaces for distribution management:
Part 1: Interface architecture and general requirements
Part 2: Glossary
Part 3: Interface standard for network operations
Part 4: Interface standard for records and asset management
The committee has decided that the contents of this publication will remain unchanged until
2004. At this date, the publication will be
• transformed into an International standard;
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
The IEC 61968 series is intended to facilitate inter-application integration, as opposed to
intra-application integration, of the various distributed software application systems supporting
the management of utility electrical distribution networks. Intra-application integration is aimed
at programs in the same application system, usually communicating with each other using
middleware that is embedded in their underlying runtime environment, and tends to be
optimized for close, real-time, synchronous connections and interactive request/reply or
conversation communication models. IEC 61968, by contrast, is intended to support the inter-
application integration of a utility enterprise that needs to connect disparate applications that
are already built or new (legacy or purchased applications), each supported by dissimilar
runtime environments. Therefore, IEC 61968 is relevant to loosely coupled applications with
more heterogeneity in languages, operating systems, protocols and management tools.
IEC 61968 is intended to support applications that need to exchange data on an event driven
basis. IEC 61968 is intended to be implemented with middleware services that broker
messages among applications, and will complement, but not replace utility data warehouses,
database gateways, and operational stores.
The series of standards will be using a lot of definitions, terms and abbreviations from the
area of distribution management as well as from the area of Information and Communication
Technology. This glossary part defines the terms and abbreviations as they are used in the
context of this series of standards.
The contents of this part 2 contains the following clauses.

Part 2: Glossary
1 Scope
This glossary, accompanying the IEC 61968 series, is the second part in the series that, taken
as a whole, define interfaces for the major elements of an interface architecture for
Distribution Management Systems (DMS). This part of IEC 61968, referred to as Part 2,
identifies and explains terms and abbreviations used in the remaining parts of IEC 61968.
As used in IEC 61968, a DMS consists of various distributed application components for the
utility to manage electrical distribution networks. These capabilities include monitoring and
control of equipment for power delivery, management processes to ensure system reliability,
voltage management, demand-side management, outage management, work management,
automated mapping and facilities management.
2 Terms and definitions
For the purposes of the IEC 61968 series, the following terms and definitions apply.
2.1
abstract component
smallest logical block of software considered in the IEC 61968 interface reference model.
Abstract components have interfaces that will be defined in future parts 3 to 10 of the
IEC 61968 series. It is expected that different vendors will supply physical Application
Components that support the interfaces for one or more abstract components
2.2
adapter
layer of software that connects one component, for example an application, to another
component, for example an interface implementation or a middleware implementation
NOTE Same as object adapter.
2.3
address/network connection
linkage of customer to premise to electrical feeder
2.4
application component
block of software with specific functions and interfaces. A distribution management system is
considered to be a set of one or more applications. Each application consists of one or more
application components
2.5
attribute
identifiable association between an object and a value. An attribute is a property of an object
2.6
audit trail
information saved in a sequential form so that an event can be traced back to its origin

TS 61968-2  IEC:2003(E) – 7 –
2.7
automated mapping/geofacilities
geospatial management system utilizing computer graphics technology to enter, store, and
update graphic and non-graphic information. Automated mapping reduces the cost and effort
in map creation and maintenance and facility record keeping. An automated mapping/
geospatial system processes geographic depictions and related non-graphic data elements for
each entity stored in a digital database. The graphic representations are referenced using a
coordinate system that relates to locations on the surface of the earth. Information in the
database can be queried and displayed based upon either the graphic or non-graphic
attributes of the entities. The system provides the utility a single, continuous electronic map of
the service territory
2.8
automatic generation control
controls generation such that average hourly generation control follows predispatch schedule.
Generation levels may be changed based on improving economic operation, emergency
conditions, or other improved conditions
