C.1.1 INTRODUCTION
The IEC 61850 standard is the result of electric utilities and vendors of electronic equipment to produce standardized com-
munications systems. IEC 61850 is a series of standards describing client/server and peer-to-peer communications, sub-
station design and configuration, testing, environmental and project standards. The complete set includes:
•
IEC 61850-1: Introduction and overview
•
IEC 61850-2: Glossary
•
IEC 61850-3: General requirements
•
IEC 61850-4: System and project management
•
IEC 61850-5: Communications and requirements for functions and device models
•
IEC 61850-6: Configuration description language for communication in electrical substations related to IEDs
•
IEC 61850-7-1: Basic communication structure for substation and feeder equipment - Principles and models
•
IEC 61850-7-2: Basic communication structure for substation and feeder equipment - Abstract communication service
interface (ACSI)
•
IEC 61850-7-3: Basic communication structure for substation and feeder equipment – Common data classes
•
IEC 61850-7-4: Basic communication structure for substation and feeder equipment – Compatible logical node classes
and data classes
•
IEC 61850-8-1: Specific Communication Service Mapping (SCSM) – Mappings to MMS (ISO 9506-1 and ISO 9506-2)
and to ISO/IEC 8802-3
•
IEC 61850-9-1: Specific Communication Service Mapping (SCSM) – Sampled values over serial unidirectional multi-
drop point to point link
•
IEC 61850-9-2: Specific Communication Service Mapping (SCSM) – Sampled values over ISO/IEC 8802-3
•
IEC 61850-10: Conformance testing
These documents can be obtained from the IEC (
). It is strongly recommended that all those involved with
any IEC 61850 implementation obtain this document set.
C.1.2 COMMUNICATION PROFILES
IEC 61850 specifies the use of the Manufacturing Message Specification (MMS) at the upper (application) layer for transfer
of real-time data. This protocol has been in existence for several of years and provides a set of services suitable for the
transfer of data within a substation LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser-
vices in IEC 61850-8-1.
The T35 relay supports IEC 61850 server services over TCP/IP. The TCP/IP profile requires the T35 to have an IP address
to establish communications. These addresses are located in the

menu. It is possible to have up to five simultaneous connections (in addition to DNP and Modbus/TCP (non-IEC
61850) connections).
•
Client/server
: This is a connection-oriented type of communication. The connection is initiated by the client, and com-
munication activity is controlled by the client. IEC 61850 clients are often substation computers running HMI programs
or SOE logging software. Servers are usually substation equipment such as protection relays, meters, RTUs, trans-
former tap changers, or bay controllers.
•
Peer-to-peer
: This is a non-connection-oriented, high speed type of communication usually between substation equip-
ment such as protection relays. GSSE and GOOSE are methods of peer-to-peer communication.
•
Substation configuration language (SCL)
: A substation configuration language is a number of files used to describe
the configuration of substation equipment. Each configured device has an
IEC Capability Description
(ICD) file. The
substation single line information is stored in a
System Specification Description
(SSD) file. The entire substation con-
figuration is stored in a
Substation Configuration Description
(SCD) file. The SCD file is the combination of the individ-
ual ICD files and the SSD file.
