What is IEC 61850?
IEC61850 is a framework for substationautomation that addresses more of what is
required for interoperability of intelligentelectronic devices (IEDs) beyond just theprotocol:
Standardized object models and naming conventions Standardized meaning of data Standardized services and device behavior models Self-describing devices Common configuration language Profiles for:
Control/SCADA Protection messaging
Transducers and I/O

Reference Models
Reference models divide the problem
according to abstract data and servicemodels.
Each layer of the model can be added toin the future without impacting otherlayers, providing a framework for futurestandardization

Substation Configuration Language
SCL IEC 61850-6-1 XML to provide a formal description of the substation
automation system, the IEDs within the substation and theswitchyard
SCL File Types:
SSD: System Specification Description.
XML description of the entire system.
SCD: Substation Configuration Description. XML description of a single substation.
ICD: IED Capability Description. XML description of items supported by an IED (required).
CID: Configured IED Description. XML configuration for a specific IED.

SCL Applications
For users to specify IED requirements.
For vendors to specify IED capabilities. Configure clients without IEDs.
Extract IED configuration from power systemdesign tools.
Export IED configuration to power system design
tools and other applications.
Enable design tools from one vendor to workwith anothers products

IEC61850 is Unique
Not a recast serial RTU protocol and does notreplace RTU protocols bandwidth limited apps.
Designed specifically for LANs to uniquely lowerthe cost to install, configure, and maintainsubstation devices.
Object-oriented with a broader scope : Supports standardized device models using names instead
of register numbers and indexes.
Abstract services with multiple protocol profiles.
Standardized configuration language (SCL).
Support for functions difficult to implement otherwise.
Conformance testing requirements defined

The benefits of IEC 61850
include lower installation and maintenance costs with self-
describing devices that reduce manualconfiguration.
wiring costs enabling more advanced protectioncapabilities via the use of direct exchange ofdata between devices over existing station bus.
communication infrastructure costs using readilyavailable TCP/IP and Ethernet technology.

What is involved in migrating to
IEC 61850?
IEC 61850 can co-exist with protocols in a
system, even running on the same network.
IEC61850 devices and clients are currently
available for substation applications.
IEC 61850 gateways and data concentrators
can be used to migrate existing systems anddevices.
