INTRODUCTION AND OVERVIEW
OF ALL THE PARTS OF IEC 61850
IEC 61850-2
GLOSSARY TERMINOLOGY
IEC 61850-3
GENERAL REQUIREMENTS
Quality requirements (reliability,maintability, system availability, portability, IT
security), operating conditions, auxiliary services and other engeneering
standards
IEC 61850-4
SYSTEM AND PROJECT MANAGEMENT
Engeneering service requirements (parameter classification, enginering
tools, documentation), system usage cycle (productversions, factory setup,
after factory setup), qualityassurance( responsabilities, test systems, type
tests system tests, factory acceptance tests (FAT) and site acceptance tests
(SAT)
IEC 61850-5
COMMUNICATIONS REQUIREMENTS
FOR FUNCTIONS AND DEVICE MODELS
The logical nodes principles, logical communications links, items of
information for communications (PICOM), logical nodes and associated
PICOMs, functions, performance requirements (response times , etc. ),
dynamic scenarios (information flow requirements under various operating
conditions)

CONFIGURATION DESCRIPTION LANGUAGE
FOR COMMUNICATION IN ELECTRICAL SUBSTATIONS
Formal description of the single–line schemas, devices, system structure and
how they fit into the single-line schema
IEC 61850-7
-1 Basic communication structure for substation & feeder equipement
-2 Abstract communication service interface (ACSI)
-3 Common data classes
-4 Definition compatible logical node classes and data classes and their logical
addressing
IEC 61850-8-1
Specific communication service mapping (SCSM) mapping to MMS (ISO/IEC
9506 Part 1 and Part 2) and to ISO/IEC 8802-3
Communication mapping in the entire station (client-server communication for
scada functions and GOOSE and GSSE data exchange for real time
requirements, for example for trippings signals

To enhance Sepam offer
 ECI850 Sepam server
 ACE850 Interface (Ethernet coupler)
−
Allows :
Makes the whole Sepam
series 20, 40 ou 80
compatible with IEC 61850
− Sepam series 40 and 80 to be connected
directly to an Ethernet network
−
Allows existing installations
to be upgraded to IEC 61850
− IEC 61850 and Modbus TCP/IP protocols
to cohabit on the same physical medium
−
Connects up to 8 Sepam units
(to Modbus RS485 2 or 4-wir)
− inter-Sepam communication (GOOSE
service) for control-monitoring and
protection functions such as :
Sepam
−
Stores data to optimize communication
– Logic discrimination
– Inter-tripping and interlocking
