Figure 2:
IEC 61850: Principle structure of the SCL XML file
The arrows show the link between the different sections given when an IED is integrated in the
substation structure and/or in the communication structure. All needed logical nodes of an IED are
linked to the substation section by the SCL tool.
A reference to GOOSE Control Blocks (GoCB) is included in the communication section when GoCB
is configured.
3.1
The substation section
SEMOD129763-4 v4
The substation description in IEC 61850-6 clause 9 describes the arrangement of the primary
equipment. In addition, it also includes a list of the applied logical nodes and the relation of those
logical nodes to the primary equipment.
3.2
The communication section
SEMOD129771-4 v3
The organization of the physical IEDs to the communication network is independent of the substation
structure. The IEC 61850 standard defines the communication network with no relation to an existing
media or protocol. The mapping to an existing media and protocol is specified in IEC 61850–8–1.
