[!IMPORTANT]
There is a main breaking change in this version. The constructor of the class ElectricalNetwork has changed:
it accepts keyword arguments only.
it accepts the arguments lines, transformers and switches in replacement of the argument branches.
As a consequence,
the results method res_branches has been removed. Please use res_lines, res_transformers
and res_switches methods instead.
the field branches does not exist anymore. Please use the fields lines, transformers and switches.
A wheel for Python 3.13 is available.
The wheels for Windows are now available. The problem was the same as the one of the
issue 28551 of the Matplotlib repository.
237 Improvements of the Sphinx configuration.
262 Raise a proper error when a transformer is defined with null impedance.
259 The cache of the license object was not reset after the activation of a new license key.
258 #261 #263 Add basic plotting functionality in the new roseau.load_flow.plotting
module. The plot_interactive_map function plots an electrical network on an interactive map using
the folium library and the plot_voltage_phasors function plots the voltage phasors of a bus, load
or source in the complex plane. The revamped plotting section of the documentation demonstrates the
plotting functionalities available in Roseau Load Flow with examples.
258 The documentation gained a new "advanced" section with a page on floating neutrals
and a page on potential references.
257 #252 Updates to the LineParameters class:
The method from_name_lv, deprecated since version 0.6, has been removed. It can be easily
replaced by the from_geometry method.
The method from_name_mv is deprecated. A new method from_coiffier_model is added with the
same functionality and more flexibility. The new method computes the ampacity of the line based
on Coiffier's model and works with different numbers of phases.
256 #250:
Accept scalar values for the powers, currents, impedances parameters of the load classes.
Add rlf.PositiveSequence, rlf.NegativeSequence and rlf.ZeroSequence vectors for easier
creation of balanced quantities.
255 Update the figures of loads and of voltage sources in the documentation to be compliant with the work
of #249.
254 #251 Allow passing multiple phases to potential references. The phase
attribute of the PotentialRef is replaced by phases.
249 #248 Accept scalar values for the voltages parameter of the VoltageSource class.
247 Add connect_neutral parameter to the loads and sources constructor to specify if the
neutral is to be connected to the bus's neutral or to be left floating. This allows loads connected
to the same bus to have different neutral connections. The default behavior remains the same as
before where the neutral is connected when the bus has a neutral and floating otherwise.
246 Improvements to the rlf.converters module:
Fix series_phasor_to_sym function with series that have different phases per element.
Make calculate_voltages take array-like potentials.
Improve typing of several functions.
245 #244 Fix the LineParameters.from_geometry method to not crash when passed
unknown insulator type or None.
Add res_voltages to the VoltageSource class for symmetry with the other elements.
res_voltages is always equal to the supplied voltages for a voltage source.
243 Fix cross-sectional area of DGS line types created from line elements and special case
invalid PwF line geographical coordinates table.
240 Add tests for switches imported from DGS and improve warning and error messages.
235 BREAKING CHANGE: The constructor of the class ElectricalNetwork has changed:
it accepts keyword arguments only.
it accepts the arguments lines, transformers and switches in replacement of the argument branches.
As a consequence,
the results method res_branches has been removed. Please use res_lines, res_transformers
and res_switches methods instead.
the field branches does not exist anymore. Please use the fields lines, transformers and switches.
235 Move the Switch class into its own file roseau/load_flow/models/switches.py.
235 #239 The JSON file format number is upgraded to the version 2. All the files in version 0 or 1
can still be read. Please upgrade them manually using the following code:
