IEC and IEEE joined forces in 1999 and defined… IEC 61850 ”COMMUNICATION NETWORKS AND SYSTEMS IN SUBSTATIONS” IEC 61850 - first global standard in the Utility field – 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 electric areas – Wind power, Hydro power, Distributed Energy

Implementation in progress by all major vendors

EPRI

Fundamentals for the Standard Interoperability

The ability for IED’s from one or several manufacturer to exchange information and use the information for the their own functions.

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) or decentralized (SAS like) systems. Long term stability The standard is future proof, i.e. it is able to follow progress in communication technology as well as new system requirements.

A supplier's System Verification Centre

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 Users Group to be an IEC 61850 Competence Center. „

The SVC is thereby entitled to officially certify IEC 61850 conformity.

„

The SVC is, together with KEMA, the only test center worldwide that has reached this status.

A supplier’s IEC 61850-compliant solutions around the globe • SA-System orders November 2006, (with ABB and 3rd party IEDs):

– Total of: 100 Substations

• Projects with ABB IEDs: 150-200 (various system integrators):

• Overall ABB involved in > 250 IEC 61850 projects

Interoperability yes, but….. • •

A communication profile defines the SUBSET of a standard Different Profiles may conform to the standard but still not be interoperable IEC 61850 Profile Company A 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 be interoperable !

→ Interoperable ≠ Interoperability Each mixing of devices with systems from different manufactures must carefully be clarified in respect of the implemented profile.

Interoperable Profile 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 their IEC61850 implementation

One manufacturer… private

Two manufacturers… by chance

Three manufacturers … interoperability !

Customer Expectation on IEC 61850 • 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 – Availability
