TC57

CONFIGURATION

SCL Format• Defined in IEC 61850 Part 6

• Four different file types

• System Specification Description (SSD) – power system functions

• Substation Configuration Description (SCD) – complete substation

• IED Capabil ity Descript ion (ICD) – the data reported by a type of IED

• Configured IED Descr ipt ion(CID) – the configuration of a specific IED

• Five sections per file• Header – Identifies the configuration file

• Substation – Identifies electrical connections and functions

• Communications – Identifies addresses and subnetworks

• IED – Identifies functions and configuration of devices

• Data Type Templates – Used to build the other sections

CONFIGURATION

System Specification Description

• The system specification description f ile (.ssd) describes the singleline diagram and the substation automation functionality using theassociated logical nodes

– single line diagram connections

– logical nodes, logical node types

CONFIGURATION

IED Capability Description

• The IED capabil ity description file (.icd) describes the capabilities and(optionally) the preconfigured data model of the IED

– logical devices, logical nodes, logical node types – data sets

– control blocks – not populated

• Think of it as an “IED Template”

CONFIGURATION

Configured IED Description

CID

File

IED Configuration Tool

SCD

File

• The configured IED descript ion file (.cid) describes an instantiated IED with

all configuration parameters relevant for that IED

• Created by the IED configuration tool from the .scd file

• Includes the device-specific configuration data

• Use of the .cid file to configure the IED is optional.

• As an alternate solution, a vendor specific file may be used


10/13

TC57

CONFIGURATION

SCL Substation Section

• Concepts of voltage level, bay, power functionality

• Associates Logical Nodes (functions) with:

– Electrical connections (required) – IEDs (optional)

• Can be used to build a one-line diagram


11/13

TC57

CONFIGURATION

SCL Communications Section

• Concepts of subnetwork, and access point

• Identifies communications addresses of IEDs• Can be used for network management


12/13

TC57

CONFIGURATION

SCL IED and Data Type Sections

• Defines the object model of each device

• Shows correspondence between devices and access points

• Shows structure of server, logical devices, logical nodes, dataobjects, data attributes, data types

• Same information as available from self-description
