Draft 61850-7-3 IEC:2002 – 8 – 57/WG10-12(61850-7-3)R7.10/DraftFDIS COMMUNICATION NETWORKS AND SYSTEMS IN SUBSTATIONS Part 7-3: Basic communication structure for substations and feeder equipment – Common data classes 1 Scope This part of IEC 61850 specifies common attribute types and common data classes related to substation applications. In particular it specifies: • common data classes for status information, • common data classes for measured information, • common data classes for controllable status information, • common data classes for controllable analogue set point information, • common data classes for status settings, • common data classes for analogue settings and • attribute types used in these common data classes. This international standard is applicable to the description of device models and functions of substations and feeder equipment. This international standard may also be applied, for example, to describe device models and functions for: • substation to substation information exchange, • substation to control centre information exchange, • power plant to control centre information exchange, • information exchange for distributed generation or • information exchange for metering
