cimpy.cgmes_v2_4_15.PhaseTapChangerAsymmetrical module

class cimpy.cgmes_v2_4_15.PhaseTapChangerAsymmetrical.PhaseTapChangerAsymmetrical(windingConnectionAngle=0.0, *args, **kw_args)

Describes the tap model for an asymmetrical phase shifting transformer in which the difference voltage vector adds to the primary side voltage. The angle between the primary side voltage and the difference voltage is named the winding connection angle. The phase shift depends on both the difference voltage magnitude and the winding connection angle.

windingConnectionAngle:

The phase angle between the in-phase winding and the out-of -phase winding used for creating phase shift. The out-of-phase winding produces what is known as the difference voltage. Setting this angle to 90 degrees is not the same as a symmemtrical transformer. Default: 0.0

Documentation of parent class PhaseTapChangerNonLinear:

The non-linear phase tap changer describes the non-linear behavior of a phase tap changer. This is a base class for the symmetrical and asymmetrical phase tap changer models. The details of these models can be found in the IEC 61970-301 document.

voltageStepIncrement:

The voltage step increment on the out of phase winding specified in percent of nominal voltage of the transformer end. Default: 0.0

xMax:

The reactance depend on the tap position according to a u shaped curve. The maximum reactance (xMax) appear at the low and high tap positions. Default: 0.0

xMin:

The reactance depend on the tap position according to a u shaped curve. The minimum reactance (xMin) appear at the mid tap position. Default: 0.0

Documentation of parent class 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.

TransformerEnd:

Phase tap changer associated with this transformer end. Default: None

Documentation of parent class TapChanger:

Mechanism for changing transformer winding tap positions.

SvTapStep:

The tap step state associated with the tap changer. Default: None

TapChangerControl:

The tap changers that participates in this regulating tap control scheme. Default: None

TapSchedules:

A TapSchedule is associated with a TapChanger. Default: “list”

controlEnabled:

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

highStep:

Highest possible tap step position, advance from neutral. The attribute shall be greater than lowStep. Default: 0

lowStep:

Lowest possible tap step position, retard from neutral Default: 0

ltcFlag:

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

neutralStep:

The neutral tap step position for this winding. The attribute shall be equal or greater than lowStep and equal or less than highStep. Default: 0

neutralU:

Voltage at which the winding operates at the neutral tap setting. Default: 0.0

normalStep:

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 or greater than lowStep and equal or less than highStep. Default: 0

step:

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 changers has yet been designed, a solutions where a narrow voltage band force the tap step to oscillate or accommodate for a continuous solution as input. The attribute shall be equal or greater than lowStep and equal or less than highStep. Default: 0.0

Documentation of parent class PowerSystemResource:

A power system resource can be an item of equipment such as a switch, an equipment container containing many individual items of equipment such as a substation, or an organisational entity such as sub-control area. Power system resources can have measurements associated.

Controls:

Regulating device governed by this control output. Default: “list”

Location:

Location of this power system resource. Default: None

Measurements:

The power system resource that contains the measurement. Default: “list”

Documentation of parent class IdentifiedObject:

This is a root class to provide common identification for all classes needing identification and naming attributes.

DiagramObjects:

The domain object to which this diagram object is associated. Default: “list”

description:

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. Default: ‘’

energyIdentCodeEic:

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. References: Default: ‘’

mRID:

Master resource identifier issued by a model authority. The mRID is globally 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 Edition 1, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements. Default: ‘’

name:

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

shortName:

The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum. Default: ‘’
