7.2.3
Station configuration description file types
The IEC 61850 standard defines SCL file types in the engineering sequence. These
files have a different definition, which is explained in IEC 61850-6. Three of the file
types are used in the IED's engineering process.
•
ICD = IED capability description
•
Capability description of the IED in logical nodes and their data. No
information about, for example, the communication configuration is
included.
•
An IED is already extended by default data sets and report control blocks.
They are predefined by ABB. Changes or additional data sets, for example,
are handled with IEC 61850 Configuration tool or IET600.
•
SCD = Station configuration description
•
A complete configuration description of all IEDs in a station and full
engineering of the process signals and communication structure are
included. This includes all the needed data sets and control blocks.
•
CID = Configured IED description
•
The CID file contains the information needed for configuring one specific
IED. The CID file contains the complete configuration description of the
IED: the configured IED name, communication part, data sets and all
control blocks.
•
IID = Instantiated IED description
•
The IID file contains a complete IED configuration, like the CID file. The
IID file can include references to other devices which are not present in the
file. The IID file is meant for transferring configuration data from the IED
configuration tool to a system configuration tool.
7.3
IEC 61850 engineering process
The IEC 61850 standard defines how information is communicated in a substation.
The information communication can be divided into different parts.
•
Description of the substation part, including the used logical nodes
•
Description of the IEDs with their logical nodes
•
Description of the communication network
•
Description of the engineering process
When exporting an SCL file from PCM600, the tool builds a default substation
structure and creates default data sets and control blocks for vertical communication
between the substation client and IEDs. For more information, see the IEC 61850
standards.
