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.


15/32

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

Benefits of IEC 61850


19/32

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

Th b fi f IEC 618 0


20/32

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.

Th b fit f IEC 61850


21/32

engineering and commissioning effort with

standardized models and namingconventions that eliminates manual mappingof I/O signals to power system variables.

cost to configure and deploy devices withstandardized device configuration files.

sensor and wiring costs via a high speedprocess bus that enables sharing ofinstrumentation signals between devices.

The benefits of IEC 61850

include lower


22/32

Legacy Protocol Mapping

Protocol objects must be manually mapped topower system functions for each different

device, application, and vendor.

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.
