pypowsybl.network.Network.get_2_windings_transformers#

Network.get_2_windings_transformers(all_attributes=False, attributes=None, **kwargs)[source]#

Get a dataframe of 2 windings transformers.

Parameters:

  • all_attributes (bool) – flag for including all attributes in the dataframe, default is false

  • attributes (List[str] | None) – attributes to include in the dataframe. The 2 parameters are mutually exclusive. If no parameter is specified, the dataframe will include the default attributes.

  • kwargs (_SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | bool | int | float | complex | str | bytes | _NestedSequence[bool | int | float | complex | str | bytes]) – the data to be selected, as named arguments.

Returns:

A dataframe of 2 windings transformers.

Return type:

DataFrame

Notes

The resulting dataframe, depending on the parameters, will include the following columns:

  • r: the resistance of the transformer at its “2” side (in Ohm)

  • x: the reactance of the transformer at its “2” side (in Ohm)

  • b: the susceptance of transformer at its “2” side (in Siemens)

  • g: the conductance of transformer at its “2” side (in Siemens)

  • rated_u1: The rated voltage of the transformer at side 1 (in kV)

  • rated_u2: The rated voltage of the transformer at side 2 (in kV)

  • rated_s:

  • p1: the active flow on the transformer at its “1” side, NaN if no loadflow has been computed (in MW)

  • q1: the reactive flow on the transformer at its “1” side, NaN if no loadflow has been computed (in MVAr)

  • i1: the current on the transformer at its “1” side, NaN if no loadflow has been computed (in A)

  • p2: the active flow on the transformer at its “2” side, NaN if no loadflow has been computed (in MW)

  • q2: the reactive flow on the transformer at its “2” side, NaN if no loadflow has been computed (in MVAr)

  • i2: the current on the transformer at its “2” side, NaN if no loadflow has been computed (in A)

  • voltage_level1_id: voltage level where the transformer is connected, on side 1

  • voltage_level2_id: voltage level where the transformer is connected, on side 2

  • bus1_id: bus where this transformer is connected, on side 1

  • bus2_id: bus where this transformer is connected, on side 2

  • bus_breaker_bus1_id (optional): bus of the bus-breaker view where this transformer is connected, on side 1

  • bus_breaker_bus2_id (optional): bus of the bus-breaker view where this transformer is connected, on side 2

  • node1 (optional): node where this transformer is connected on side 1, in node-breaker voltage levels

  • node2 (optional): node where this transformer is connected on side 2, in node-breaker voltage levels

  • connected1: True if the side “1” of the transformer is connected to a bus

  • connected2: True if the side “2” of the transformer is connected to a bus

  • fictitious (optional): True if the transformer is part of the model and not of the actual network

This dataframe is indexed by the id of the two windings transformers
