Inheritance

Attributes

Name URI Cardinality and Range Inheritance Description
capacitance cim:DCLineSegment.capacitance 1..1 Capacitance direct Capacitance of the DC line segment. Significant for cables only.
inductance cim:DCLineSegment.inductance 1..1 Inductance direct Inductance of the DC line segment. Negligible compared with DCSeriesDevice used for smoothing.
length cim:DCLineSegment.length 0..1 Length direct Segment length for calculating line section capabilities.
resistance cim:DCLineSegment.resistance 1..1 Resistance direct Resistance of the DC line segment.
ratedUdc cim:DCConductingEquipment.ratedUdc 1..1 Voltage DCConductingEquipment Rated DC device voltage. The attribute shall be a positive value. It is configuration data used in power flow.
aggregate cim:Equipment.aggregate 0..1 boolean Equipment The aggregate flag provides an alternative way of representing an aggregated (equivalent) element. It is applicable in cases when the dedicated classes for equivalent equipment do not have all of the attributes necessary to represent the required level of detail. In case the flag is set to “true” the single instance of equipment represents multiple pieces of equipment that have been modelled together as an aggregate equivalent obtained by a network reduction procedure. Examples would be power transformers or synchronous machines operating in parallel modelled as a single aggregate power transformer or aggregate synchronous machine.The attribute is not used for EquivalentBranch, EquivalentShunt and EquivalentInjection.
normallyInService cim:Equipment.normallyInService 0..1 boolean Equipment Specifies the availability of the equipment under normal operating conditions. True means the equipment is available for topology processing, which determines if the equipment is energized or not. False means that the equipment is treated by network applications as if it is not in the model.
EquipmentContainer cim:Equipment.EquipmentContainer 0..1 EquipmentContainer Equipment Container of this equipment.
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.
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.
energyIdentCodeEic eu:IdentifiedObject.energyIdentCodeEic 0..1 string IdentifiedObject The attribute is used for an exchange of the EIC code (Energy identification Code). The length of the string is 16 characters as defined by the EIC code. For details on EIC scheme please refer to ENTSO-E web site.
name cim:IdentifiedObject.name 1..1 string IdentifiedObject The name is any free human readable and possibly non unique text naming the object.
shortName eu:IdentifiedObject.shortName 0..1 string IdentifiedObject The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum.
