The number of data objects and data attributes per DO is defined by the used LN type
in the IED. The content of logical node types and DO types are defined in the DTT.
This also means that the definitions in the DTT section have to be unique within an
SCD file.
3.4
Tool concept
The IEC 61850-6 defines a number of roles for tools. In the Relion
®
series, PCM600
is defined as the IED tool, and IET600 is defined as the system engineering tool.
The sections in SCL contain properties that are to be configured by these tools. There
is no relation between one section and one specific tool. The task of the IED tool is to
configure all properties for the IED, while the system tool has the task to define the
place of the IED in the system and its communication dependencies. For example, the
plant structure in PCM600 results in the subsystem section in SCL regarding the
subsystem structure down to the IED level. The PCM600 also configures the IED
section as a result of the IED configuration. In PCM600, the configuration properties
for SCL are handled automatically as a result of the configuration, except for the
receiving of GOOSE information that has a dependency with the system tool.
IEC 61850 engineering with PCM600, PCM600 IEC61850 Configuration tool and
IET600
PCM600:
•
When an IED is instantiated, its place in the plant structure creates the
corresponding structure in the substation section in SCL. The communication
facilities is also created in the communication section.
•
The functionality of the IED is configured by using ACT in PCM600. For each
function, the corresponding logical device and logical node(s) is created in the
IED section together with its type definition in data type template section
•
The above forms the IED capabilities from a communication perspective and will
then be included in the file exported from PCM600 as SCD, ICD, IID and CID file
PCM600: IEC61850 Configuration tool
•
Included in PCM600 is the new IEC61850 Configuration tool which allows the
user to define data sets and control blocks for both Client Server and GOOSE
communication.
•
The IEC61850 Configuration tool gives the user the possibility to make the
IEC61850 engineering without export / import step.
It does NOT however allow the User to define the substation part.
