cimpy.cgmes_v2_4_15.RatioTapChanger module
- class cimpy.cgmes_v2_4_15.RatioTapChanger.RatioTapChanger(RatioTapChangerTable=None, TransformerEnd=None, stepVoltageIncrement=0.0, tculControlMode=None, *args, **kw_args)[source]
A tap changer that changes the voltage ratio impacting the voltage magnitude but not the phase angle across the transformer.
- RatioTapChangerTable:
The ratio tap changer of this tap ratio table. Default: None
- TransformerEnd:
Ratio tap changer associated with this transformer end. Default: None
- stepVoltageIncrement:
Tap step increment, in per cent of nominal voltage, per step position. Default: 0.0
- tculControlMode:
Specifies the regulation control mode (voltage or reactive) of the RatioTapChanger. 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: ‘’
