public class NewThreeWindingsTransformerConversion extends AbstractConductingEquipmentConversion
Cgmes conversion for transformers (two and three windings) is divided into four stages: load, interpret, convert and set.
Load
Native CGMES data is loaded from the triple store query and is put in the CGMES model object (CgmesT3xModel).
Interpret
CgmesT3xModel data is mapped to a more general three windings transformer model (InterpretedT3xModel)
according to a predefined configured alternative. It is an elemental process as the only objective is to put
Cgmes data in the fields of the general three windings transformer model.
All possible alternatives and the default one are defined in conversion class. See Conversion
InterpretedT3xModel supports ratioTapChanger and phaseTapChanger at each end of any leg. Shunt admittances
can also be defined at both ends of each leg and allows to specify the end of the structural ratio by leg.
Convert
Converts the interpreted model (InterpretedT3xModel) to the converted model object (ConvertedT3xModel).
The ConvertedT3xModel only allows to define ratioTapChanger and phaseTapChanger at the network side of any leg.
Shunt admittances and structural ratio must be also at the network side.
To do this process the following methods are applied to each leg:
moveTapChangerFrom2To1: To move a tapChanger from star bus side to network side
combineTapChanger: To reduce two tapChangers to one
moveRatioFrom2To1: To move structural ratio from star bus side to network side
Finally shunt admittance of both ends of the leg are added to network side. This step is an approximation and only
will be possible to reproduce the exact case result if Cgmes shunts are defined at network side or
are split and the LoadflowParameter splitShuntAdmittance option is selected.
