dragonfly_energy.opendss.connector module

Electrical connector in OpenDSS.

class dragonfly_energy.opendss.connector.ElectricalConnector(identifier, geometry, power_line)[source]

Bases: _GeometryBase

Represents an electrical connector carrying wires in OpenDSS.

Parameters

  • identifier – Text string for a unique electrical connector ID. Must contain only characters that are acceptable in OpenDSS. This will be used to identify the object across the exported geoJSON and OpenDSS files.

  • geometry – A LineSegment2D or Polyline2D representing the geometry of the electrical connector.

  • power_line – A PowerLine object representing the wires carried along the electrical connector and their arrangement.

Properties:

  • identifier

  • display_name

  • geometry

  • power_line

  • phase_count

  • nominal_voltage

ToString()
duplicate()

Get a copy of this object.

classmethod from_dict(data)[source]

Initialize an ElectricalConnector from a dictionary.

Parameters

data – A dictionary representation of an ElectricalConnector object.

classmethod from_dict_abridged(data, power_lines)[source]

Initialize an ElectricalConnector from an abridged dictionary.

Parameters

  • data – A ElectricalConnectorAbridged dictionary.

  • power_lines – A dictionary with identifiers of PowerLines as keys and Python PowerLine objects as values.

classmethod from_rnm_geojson_dict(data, origin_lon_lat, conversion_factors, power_lines)[source]

Get an ElectricalConnector from a dictionary as it appears in an RNM GeoJSON.

Parameters

  • data – A GeoJSON dictionary representation of an ElectricalConnector feature.

  • origin_lon_lat – An array of two numbers in degrees. The first value represents the longitude of the scene origin in degrees (between -180 and +180). The second value represents latitude of the scene origin in degrees (between -90 and +90). Note that the “scene origin” is the (0, 0) coordinate in the 2D space of the input polygon.

  • conversion_factors – A tuple with two values used to translate between meters and longitude, latitude.

  • power_lines – A dictionary with identifiers of PowerLines as keys and Python PowerLine objects as values.

move(moving_vec)

Move this object along a vector.

Parameters

moving_vec – A ladybug_geometry Vector3D with the direction and distance to move the object.

reflect(plane)

Reflect this object across a plane.

Parameters

plane – A ladybug_geometry Plane across which the object will be reflected.

rotate_xy(angle, origin)

Rotate this object counterclockwise in the XY plane by a certain angle.

Parameters

  • angle – An angle in degrees.

  • origin – A ladybug_geometry Point3D for the origin around which the object will be rotated.

scale(factor, origin=None)

Scale this object by a factor from an origin point.

Parameters

  • factor – A number representing how much the object should be scaled.

  • origin – A ladybug_geometry Point3D representing the origin from which to scale. If None, it will be scaled from the World origin (0, 0, 0).

to_dict(abridged=False)[source]

ElectricalConnector dictionary representation.

Parameters

abridged – Boolean to note whether the full dictionary describing the object should be returned (False) or just an abridged version (True), which only specifies the identifier of the power line. (Default: False).

to_geojson_dict(start_id, end_id, origin_lon_lat, conversion_factors)[source]

Get ElectricalConnector dictionary as it appears in an URBANopt geoJSON.

Parameters

  • start_id – Identifier of the junction at the start of the wire.

  • end_id – Identifier of the junction at the end of the wire.

  • origin_lon_lat – An array of two numbers in degrees. The first value represents the longitude of the scene origin in degrees (between -180 and +180). The second value represents latitude of the scene origin in degrees (between -90 and +90). Note that the “scene origin” is the (0, 0) coordinate in the 2D space of the input polygon.

  • conversion_factors – A tuple with two values used to translate between meters and longitude, latitude.

property display_name

Get or set a string for the object name without any character restrictions.

If not set, this will be equal to the identifier.

property geometry

Get a LineSegment2D or Polyline2D representing the electrical connector.

property identifier

Get or set the text string for unique object identifier.

property nominal_voltage

Get an integer for the nominal voltage of this connector.

property phase_count

Get an integer for the number of phases this connector supports.

property power_line

Get or set the PowerLine object carried along the electrical connector.
