ImpedanceRecords Module¶

This module contains all Harmonic Impedance record information for passing data to and from the ERACS Harmonic Impedance calculation engine.

class THZSetUpData(*args)¶

The setup object for Harmonic Impedance. This class contains the record structure which is passed to the Harmonic Impedance module.

Inherits: Global.TEracsEngineInterfaceSetupData.

property StudyTitle¶

Harmonic Impedance study title.

Type: str.
Writable: True.

property StudyType¶

Harmonic Impedance study type (harmonic survey? 0 = No, 1 = Yes).

Type: int.
Writable: True.

property HarmOff¶

Harmonic Offset for study.

Type: float.
Writable: True.

property HarmMin¶

Lowest harmonic.

Type: float.
Writable: True.

property HarmMax¶

Highest harmonic.

Type: float.
Writable: True.

property HarmInt¶

Harmonic intervals.

Type: float.
Writable: True.

property OutputUnits¶

The output units of the Harmonic Impedance study.

Type: int.
Writable: True.

property InjectionBus¶

Sequence number of the Injection busbar.

Type: int.
Writable: True.

SetDefaults()¶

Sets the default values for all setup data for the Harmonic Impedance study, this sets the values in the underlying ctypes record structure.

Raises: TEracsDataError – If missing keys.

class TImpedanceProfileData(*args)¶

The impedance profile data object for Grids and Shunts. This class contains the record structure which is passed to the Harmonic Impedance module, and exposes all relevant properties.

Inherits: Global.TEracsEngineInterfaceData.

property pSeqNum¶

Profile parent sequence number (element the impedance profile is associated with).

Type: str.
Writable: True.

property pTypeCode¶

Profile parent type code (element the impedance profile is associated with).

Type: int.
Writable: True.

property ConvInd¶

Impedance conversion indicator, possible values are… (0 = Ohms, 1 = pu on system base, 2 = percentage on system base).

Type: int.
Writable: True.

property NumValues¶

Number of harmonic impedance profiles.

Type: int.
Writable: True.

property Profile¶

The profiles associated with this impedance profile record.

Type: Array.
Writeable: False.

SetDefaults()¶: Sets the default values for the harmonic impedance profile data.

LoadFromDict(AParentDict)¶

An impedance profile dictionary is passed in and desired key-value pairs are used to populate certain data fields within the record.

Parameters: AParentDict (dict) – The parent dictionary which contains seqnum and typecode, as well as embedded impedance profile data.
Returns: None
Raises: TEracsDataError – If the winding dictionary is missing required keys.

class THZSummaryResults(*args)¶

Summary results for the Harmonic Impedance study.

Inherits: Global.TEracsEngineInterfaceResult.

class THZBusbarResult(*args)¶

Busbar results for the Harmonic Impedance study.

Inherits: Global.TEracsEngineInterfaceResultElement.
