PhaseTapChanger

A transformer phase shifting tap model that controls the phase angle difference across the power transformer and potentially the active power flow through the power transformer. This phase tap model may also impact the voltage magnitude.

Inheritance

Attributes

Name URI Cardinality and Range Description Inheritance
TransformerEnd cim:PhaseTapChanger.TransformerEnd No cardinality available TransformerEnd Transformer end to which this phase tap changer belongs. direct
TapSchedules cim:TapChanger.TapSchedules No cardinality available TapSchedule A TapChanger can have TapSchedules. TapChanger
highStep cim:TapChanger.highStep No cardinality available integer Highest possible tap step position, advance from neutral.
The attribute shall be greater than lowStep. TapChanger
lowStep cim:TapChanger.lowStep No cardinality available integer Lowest possible tap step position, retard from neutral. TapChanger
ltcFlag cim:TapChanger.ltcFlag No cardinality available boolean Specifies whether or not a TapChanger has load tap changing capabilities. TapChanger
neutralStep cim:TapChanger.neutralStep No cardinality available integer The neutral tap step position for this winding.
The attribute shall be equal to or greater than lowStep and equal or less than highStep.
It is the step position where the voltage is neutralU when the other terminals of the transformer are at the ratedU. If there are other tap changers on the transformer those taps are kept constant at their neutralStep. TapChanger
neutralU cim:TapChanger.neutralU No cardinality available Voltage Voltage at which the winding operates at the neutral tap setting. It is the voltage at the terminal of the PowerTransformerEnd associated with the tap changer when all tap changers on the transformer are at their neutralStep position. Normally neutralU of the tap changer is the same as ratedU of the PowerTransformerEnd, but it can differ in special cases such as when the tapping mechanism is separate from the winding more common on lower voltage transformers.
This attribute is not relevant for PhaseTapChangerAsymmetrical, PhaseTapChangerSymmetrical and PhaseTapChangerLinear. TapChanger
normalStep cim:TapChanger.normalStep No cardinality available integer The tap step position used in "normal" network operation for this winding. For a "Fixed" tap changer indicates the current physical tap setting.
The attribute shall be equal to or greater than lowStep and equal to or less than highStep. TapChanger
TapChangerControl cim:TapChanger.TapChangerControl No cardinality available TapChangerControl The regulating control scheme in which this tap changer participates. TapChanger
description cim:IdentifiedObject.description No cardinality available string 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. IdentifiedObject
energyIdentCodeEic eu:IdentifiedObject.energyIdentCodeEic No cardinality available string 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. IdentifiedObject
mRID cim:IdentifiedObject.mRID No cardinality available string 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. IdentifiedObject
name cim:IdentifiedObject.name No cardinality available string The name is any free human readable and possibly non unique text naming the object. IdentifiedObject
shortName eu:IdentifiedObject.shortName No cardinality available string The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum. IdentifiedObject
