Technical data

The plant structure corresponds to the complete grid including the
needed IEDs.
Procedure to build a plant structure:
• Right-click the plant structure and select New and Create from Template ..., or
• Right-click in the plant structure and select New, General and select one of the
elements IED Group or Substation.
• Click View in the menu bar and select Object Types. Select the needed elements
and drag and drop them into the plant structure. Close the window if it does not
close automatically.
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.
