ACLineSegment

A wire or combination of wires, with consistent electrical characteristics, building a single electrical system, used to carry alternating current between points in the power system.For symmetrical, transposed three phase lines, it is sufficient to use attributes of the line segment, which describe impedances and admittances for the entire length of the segment. Additionally impedances can be computed by using length and associated per length impedances.The BaseVoltage at the two ends of ACLineSegments in a Line shall have the same BaseVoltage.nominalVoltage. However, boundary lines may have slightly different BaseVoltage.nominalVoltages and variation is allowed. Larger voltage difference in general requires use of an equivalent branch.

Inheritance

Attributes

Name URI Cardinality and Range Inheritance Description
ACLineSegmentSpan nc-no:ACLineSegment.ACLineSegmentSpan 0..* ACLineSegmentSpan direct The associated AC Line Segment
locationMethodKind nc-no:PowerSystemResource.locationMethodKind 0..1 LocationMethodKind PowerSystemResource Possible methods to derive geographical location.
mRID cim:IdentifiedObject.mRID 0..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.
description cim:IdentifiedObject.description 0..1 string IdentifiedObject The description is a free human readable text describing or naming the object. It may be non unique and may not correlate to a naming hierarchy.
name cim:IdentifiedObject.name 0..1 string IdentifiedObject The name is any free human readable and possibly non unique text naming the object.
