TopologicalIsland

An electrically connected subset of the network. Topological islands can change as the current network state changes, e.g. due to:- disconnect switches or breakers changing state in a SCADA/EMS.- manual creation, change or deletion of topological nodes in a planning tool.Only energised TopologicalNode-s shall be part of the topological island.

Inheritance

Attributes

Name URI Cardinality and Range Inheritance Description
AngleRefTopologicalNode cim:TopologicalIsland.AngleRefTopologicalNode 1..1 TopologicalNode direct The angle reference for the island. Normally there is one TopologicalNode that is selected as the angle reference for each island. Other reference schemes exist, so the association is typically optional.
TopologicalNodes cim:TopologicalIsland.TopologicalNodes 1..* TopologicalNode direct A topological node belongs to a topological island.
mRID cim:IdentifiedObject.mRID 1..1 string IdentifiedObject Master resource identifier issued by a model authority. The mRID is unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended.For CIMXML data files in RDF syntax conforming to IEC 61970-552, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements.
name cim:IdentifiedObject.name 1..1 string IdentifiedObject The name is any free human readable and possibly non unique text naming the object.
