4.6.1
IEC 61850 naming conventions to identify an IED
This section is only valid when the IEC 61850 standard is used for station bus
communication. According to the IEC 61850–6 clause 8.4, the SCL model allows
two kinds of project designation in the object properties.
•
A technical key is used on engineering drawings and for signal identifications.
This is contained in the attribute name as identification of each object. If this
value is used as reference to an object, it is contained in an attribute name
starting with a string denoting the reference target object type, and ending with
the string
Name
. The technical key is used within SCL for referencing other
objects. Observe that name is a relative identification within a hierarchy of
objects.
•
A user oriented textual designation is contained in attribute desc. Attributes are
not allowed to contain carriage return, line feed or tab characters. The
semantics of desc shall also be relative within an object hierarchy.
PCM600 takes care of these two possibilities. The two possible signal designations
are available per object in the object properties for all hierarchical levels beginning
with the station as the highest level.
The technical key is automatically generated based on the rules and type
specifications of IEC 61346 and the extended definitions done for substations by a
technical committee. The technical key is shown in the
Object Properties
under
SCL Technical Key
or
Technical Key
.
•
The station level is predefined by "AA1", where 1 is the index.
•
The voltage level is predefined by "J1", where 1 is the index.
•
The bay level is predefined by "Q01", where 01 is the index.
•
The IED is predefined by "A1", where 1 is the index.
The predefined full path name of the technical key for the IED would be
AA1J1Q01A1.
For all practical engineering purposes (both towards the IED and towards the
61850 engineering process), the user should keep the default SCL technical key. It
is however possible, due to for example company naming policies, to rename the
SCL technical key for the station level, voltage level, bay level and IED level using
the Object properties window as shown in
