Iec 61850 standardises the whole structure of communications

IEC 61850 standardises the whole structure of communications

  • A standard for a common communication system architecture inside a substation

  • A standard to define functionalitiesof devices

  • A standardised devicedescriptionlanguage

Iec 61850 document communication networks and systems in substations

IEC 61850 Document: Communication networks and systems in substations

IEC 61850-1 INTRODUCTION AND OVERVIEW

OF ALL THE PARTS OF IEC 61850

IEC 61850-6 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 61850-2 GLOSSARY TERMINOLOGY

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 61850-3 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 61850-8-1

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

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)

IEC 61850-9 Specific communication service mapping (SCSM)

-1 Sample values over serial unidirectional multidrop point to point link

-2 Sample values over ISO/IEC 8802-3
