7.2.3
Station configuration description file types
The IEC 61850 standard defines SCL file types in the sequence of engineering. These
files have a different definition, which is explained in IEC 61850-6. Three of the file
types are used in the engineering process for an IED.
•
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,
have to be done with IEC 61850 Configuration tool or IET600.
•
SCD = Station configuration description
•
A complete configuration description of all IEDs in a station and the full
engineering of process signals and communication structure is 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 one
specific IED. This includes 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 IED
configuration tool to a system configuration tool.
The uploading of IEC 61850 communication configuration is not
supported when reading a configuration from an online IED. The
PCM600 project works as a repository for the IEC 61850
configuration.
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
