pypowsybl.network.Network.get_voltage_levels¶

Network.get_voltage_levels(all_attributes=False, attributes=None, **kwargs)[source]¶

Get a dataframe of voltage levels.

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 (Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str]) – the data to be selected, as named arguments.

Returns:

A dataframe of voltage levels.

Return type:

DataFrame

Notes

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

substation_id: at which substation the voltage level belongs

nominal_v: The nominal voltage

high_voltage_limit: the high voltage limit

low_voltage_limit: the low voltage limit

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

topology_kind (optional): the voltage level topology kind (NODE_BREAKER or BUS_BREAKER)

This dataframe is indexed by the id of the voltage levels

Examples

net = pp.network.create_four_substations_node_breaker_network()
net.get_voltage_levels()

will output something like:

	substation_id	nominal_v	high_voltage_limit	low_voltage_limit
id
S1VL1	S1	225.0	240.0	220.0
S1VL2	S1	400.0	440.0	390.0
S2VL1	S2	400.0	440.0	390.0
S3VL1	S3	400.0	440.0	390.0
S4VL1	S4	400.0	440.0	390.0

net = pp.network.create_four_substations_node_breaker_network()
net.get_voltage_levels(all_attributes=True)

will output something like:

	substation_id	nominal_v	high_voltage_limit	low_voltage_limit
id
S1VL1	S1	225.0	240.0	220.0
S1VL2	S1	400.0	440.0	390.0
S2VL1	S2	400.0	440.0	390.0
S3VL1	S3	400.0	440.0	390.0
S4VL1	S4	400.0	440.0	390.0

net = pp.network.create_four_substations_node_breaker_network()
net.get_voltage_levels(attributes=['substation_id','nominal_v'])

will output something like:

	substation_id	nominal_v
id
S1VL1	S1	225.0
S1VL2	S1	400.0
S2VL1	S2	400.0
S3VL1	S3	400.0
