TapChanger

The aliasName is free text human readable name of the object alternative to IdentifiedObject.name. It may be non unique and may not correlate to a naming hierarchy. The attribute aliasName is retained because of backwards compatibility between CIM relases. It is however recommended to replace aliasName with the Name class as aliasName is planned for retirement at a future time.

Datasheet information for this power system resource.

All assets represented by this power system resource. For example, multiple conductor assets are electrically modelled as a single AC line segment.

All clearances applicable to this power system resource.

All configuration events created for this Power System resource.

Specifies the regulation status of the equipment. True is regulating, false is not regulating.

The controller outputs used to actually govern a regulating device, e.g. the magnetization of a synchronous machine or capacitor bank breaker actuator.

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.

The diagram objects that are associated with the domain object.

The generic action that is performed on the power system resource

Highest possible tap step position, advance from neutral. The attribute shall be greater than lowStep.

For an LTC, the delay for initial tap changer operation (first step change).

Dataset containing the data objects.

Location of this power system resource.

Lowest possible tap step position, retard from neutral.

Specifies whether or not a TapChanger has load tap changing capabilities.

The measurements associated with this power system resource.

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.

The name is any free human readable and possibly non unique text naming the object.

All names of this identified object.

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.

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.

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.

The operating shares of this power system resource.

All operational tags placed on this power system resource.

The single CIM data object in the appropriate dataset context.

All events associated with this power system resource.

Custom classification for this power system resource.

Reporting groups to which this power system resource belongs.

Tap changer position. Starting step for a steady state solution. Non integer values are allowed to support continuous tap variables. The reasons for continuous value are to support study cases where no discrete tap changer has yet been designed, a solution where a narrow voltage band forces the tap step to oscillate or to accommodate for a continuous solution as input. The attribute shall be equal to or greater than lowStep and equal to or less than highStep.

For an LTC, the delay for subsequent tap changer operation (second and later step changes).

The tap step state associated with the tap changer.

The regulating control scheme in which this tap changer participates.

A TapChanger can have TapSchedules.
