IEC and IEEE joined forces in 1999 and

defined…IEC 61850

” COMMUNICATION NETWORKS AND SYSTEMS IN SUBSTATIONS”

EPRI

IEC 61850 - first global standard in the Utili ty f ield

– Supported by ANSI/IEEE

Developed by 60 experts from Europe and North

America – Includes the UCA 2.0 as a subset

Starts to Influence related electr ic areas

– Wind power, Hydro power, Distributed Energy

Implementation in progress by all major vendors

Fundamentals for the Standard

Free configuration The standard supports different philosophies

and allow a free allocation of functions e.g. it must

work equally well for centralized (RTU like) ordecentralized (SAS like) systems.

Interoperability The ability for IED’s from one or several

manufacturer to exchange information and use

the information for the their own functions.

Long term stability The standard is future proof , i.e. it is able to follow

progress in communication technology as well asnew system requirements.

SVC (System Verification Center) qualified by UCA

IEC 61850; SVC Recognized

conformance test center

June 2006 - The SVC (in Baden/Switzerland)

certified by the UCA International UsersGroup to be an IEC 61850 Competence

Center.

The SVC is thereby entitled to officially certifyIEC 61850 conformity.

The SVC is, together with KEMA, the only

test center worldwide that has reached this

status.

Profile Company B

Interoperable

Interoperable? - An example:

IEC61850 defines three types of

data exchange communication

services – but only one of these

must be supported to beinteroperable !

Interoperable Interoperability

Each mixing of devices with systems from

different manufactures must carefully beclarified in respect of the implementedprofile.

Interoperability yes, but…..

• A communication profile defines the SUBSET of a standard

• Different Profiles may conform to the standard but still not be interoperable

7/23/2019 Abb iec61850


Key players• An important part of the standard has been successfully tested

between the key suppliers

• Different interpretation of the standard was detected during the tests

• ABB, and 2 of our main competitors have synchronized theirIEC61850 implementation

Interoperable Profile

One manufacturer…

private

Two manufacturers…

by chanceThree manufacturers …

interoperabili ty !

7/23/2019 Abb iec61850


• Cost effective solutions supporting reuse of engineering

data over time and a reduced need for training

• The data model will contribute to long term stable

solutions.

• Interoperable

• Main stream technology path for major suppliers –
