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.

INTRODUCTION
This part of IEC 61850 is part of set of standards, the IEC 61850 series. The IEC 61850
series is intended to provide interoperability between all devices in power utility automation
systems. Therefore, it defines communication networks and systems for power utility
automation, and more specially the communication architecture for subsystems like substation
automation systems. The sum of all subsystems may result also in the description of the
communication architecture for the overall power system management.
Communication between these devices in subsystems and between the subsystems within the
overall power utility automation system fulfils a lot of requirements imposed by all the
functions to be performed in power utility automation systems starting from the core
requirements in substations. These requirements are stated both for the data to be organized
in a data model and for the data exchange resulting in services. Performance of the data
exchange means not only transfer times but also the quality of the data exchange avoiding
losses of information in the communication.
Depending on the philosophy both of the vendor and the user and on the state-of-the-art in
technology, the allocation of functions to devices and control levels is not commonly fixed.
Therefore, the standard shall support any allocation of functions. This results in different
requirements for the different communication interfaces within the substation or plant, at its
border and beyond.
The standard series shall be long living but allow following the fast changes in communication
technology by both its technical approach and its document structure. Figure 1 shows the
relationship of Part 5 to subsequent parts of IEC 61850 series.
The standard series IEC 61850 has been organized so that at least minor changes to one part
do not require a significant rewriting of another part. For example, the derived data models in
subsequent parts (IEC 61850-7-x) and mappings to dedicated stacks (IEC 61850-8-x and
IEC 61850-9-x) based on the communication requirements in Part 5 will not change the
requirements defined in Part 5. In addition, the general parts, the requirement specification
and the modelling parts are independent from any implementation. The implementation
needed for the use of the standard is defined in some few dedicated parts referring to main
stream communication means thus supporting the long living of the standard and its potential
for later technical changes.
This Part 5 of the standard IEC 61850 defines the communication requirements for functions
and device models for power utility automation systems.
The modelling of communication requires the definition of objects (e.g., data objects, data
sets, report control, log control) and services accessing the objects (e.g., get, set, report,
create, delete). This is defined in Part 7 with a clear interface to implementation. To use the
benefits of communication technology, in this standard no new protocol stacks are defined but
a standardized mapping on existing stacks is given in Part 8 and Part 9. A System
configuration language (Part 6) for strong formal description of the system usable for software
tools and a standardized conformance testing (Part 10) complement the standard. Figure 1
shows the general structure of the documents of IEC 61850 as well as the position of the
clauses defined in this document.
NOTE To keep the layered approach of the standard not mixing application and implementation requirements,
terms like client, server, data objects, etc. are normally not used in Part 5 (requirements). In Parts 7 (modelling), 8
and 9 (specific communication service mapping) terms belonging to application requirements like PICOM are
normally not used.

COMMUNICATION NETWORKS AND SYSTEMS
FOR POWER UTILITY AUTOMATION –

Part 5: Communication requirements
for functions and device models

1 Scope
This part of IEC 61850 applies to power utility automation systems with the core part of
substation automation systems (SAS). It standardizes the communication between intelligent
electronic devices (IEDs) and defines the related system requirements to be supported.
The specifications of this part refer to the communication requirements of the functions in
power automation systems. Most examples of functions and their communication
requirements in this part are originated primarily from the substation automation domain and
may be reused or extended for other domains within power utility automation if applicable.
Note that sometimes instead of the term substation automation domain the term substation
domain is used, especially if both the switchyard devices (primary system) and the automation
system (secondary system) is regarded.
The description of the functions is not used to standardize the functions, but to identify
communication requirements between Intelligent Electronic Devices within plants and
substations in the power system, between such stations s (e.g. between substation for line
protection) and between the plant or substation and higher-level remote operating places (e.g.
network control centres) and maintenance places. Also interfaces to remote technical services
(e.g. maintenance centres) are considered. The general scope is the communication
requirements for power utility automation systems. The basic goal is interoperability for all
interactions providing a seamless communication system for the overall power system
management.
Standardizing functions and their implementation is completely outside the scope of this
standard. Therefore, it cannot be assumed a single philosophy of allocating functions to
devices. To support the resulting request for free allocation of functions, a proper breakdown
of functions into parts relevant for communication is defined. The exchanged data and their
required performance are defined.
The same or similar intelligent electronic devices from substations like protective and control
devices are found in other installations like power plants also. Using this standard for such
devices in these plants facilitates the system integration e.g. between the power plant control
and the related substation automation system. For some of such other application domains
like wind power plants, hydro power plants and distributed energy resources specific standard
parts according to IEC 61850 series have been already defined and published.
