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.
In the following example, it is assumed that PCM600 and any IEC 61850 System Configuration Tool are used as the system configuration tools. Another option is to use IEC 61850 Configuration tool or Application Configuration in PCM600. In that case, the SCL file export and import (steps 1 and 3) are not needed. For more information on the GOOSE engineering in IEC 61850 Configuration tool and Application Configuration, see the IEC 61850 engineering guide.
- SCL files are exported from PCM600. In this case, a SCD file. It is also possible to export other SCL file types.
- Horizontal and vertical communication is configured using any IEC 61850 System Configuration Tool.
- SCL files are imported to a PCM600 project. In this case, it is the updated SCD file.
