CEI CLC/TS 61850-80-1

Scope and object

This technical specification gives a guideline on how to
exchange information from a CDCbased data model (for example IEC
61850) using IEC 60870-5-101 or IEC 60870-5-104 between
substation(s) and control center(s). Mostly guidelines for
functions needed in a substation gateway device are given.

The goal of this technical specification is to describe
standardized mapping of device-oriented data models (for example
IEC 61850) with already defined attributes of CDC's and services
(for example IEC 61850-7) onto the already defined ASDU's and
services of IEC 60870-5-104 or IEC 60870-5-101.

It is not the goal of this technical specification to add any
extensions to published standards (for example IEC 61850 or IEC
60870-5-104 or IEC 60870-5-101). After an introduction giving a
basic description of the mapping, the mapping of the information
model with associated data classes, and the mapping of services are
described. Clause 9 shows how the mapped data and services
according to the IEC 60870-5-104 and IEC 60870-5-101 protocol are
marked (selected) in the interoperability sheet.

The scope of this technical specification is to achieve
real-time exchange of process information required for operational
purposes between a substation using a CDC-based data model (for
example IEC 61850) and (a) control centre(s) using a communication
link over a wide area network (WAN) compliant to the definitions of
IEC 60870-5-101 or IEC 60870-5- 104. The amount of real-time
information provided by the substation-gateway device can vary
dependent on the operational needs. Actors could be regional and
nationwide control centers that receive real-time information in
order to monitor and control geographically widespread processes.
The described mapping can be used for several fields of application
of power utilities, such as substations, hydro and wind power
plants, and decentralized energy resources DER. The mapping is
based on the definitions of the standard series IEC 61850 Edition
1.0 and IEC 60870-5-104:2006/IEC 60870-5-101:2003. The scope of the
mapped IEC 60870-5-104 and IEC 60870-5-101 subset is given in
Clause 9.

This technical specification focuses mainly on defining rules
and functions of a gateway device as a part of the substation.
However, the rules and functions are also valid when an IED may
optionally be connected directly to a WAN compliant with IEC
60870-5-101 or IEC 60870-5-104 and therefore, the mapping has to be
done inside the IED.
