Running a short-circuit analysis¶
You can use the module pypowsybl.shortcircuit in order to perform a shortcircuit analysis on a network.
Please check out the examples below.
For detailed documentation of involved classes and methods, please refer to the API reference.
Note that, currently, no simulator is integrated in pypowsybl to perform the short-circuit analysis.
Short-circuit analysis¶
The current APIs allow the simulation of three-phased bus faults, where the fault resistance and reactance, when specified, are connected to the ground in series.
To perform a short-circuit analysis, you need a network and at least a fault to simulate on this network. The results of the analysis contain the computed current and voltages on the network after the fault, in three-phased magnitude. Optionally, depending on specific parameters for the simulation, the results contain also
the contributions of each feeder to the short circuit current (parameter with_feeder_result)
a list of all the violations after the fault (parameter with_limit_violations)
>>> import pypowsybl as pp >>> import pypowsybl.network as pn >>> import pandas as pd >>> # create a network >>> n = pn.create_four_substations_node_breaker_network() >>> # sets some short-circuit parameters >>> pars = pp.shortcircuit.Parameters(with_feeder_result = False, with_limit_violations = False, study_type = pp.shortcircuit.ShortCircuitStudyType.TRANSIENT) >>> # create a short-circuit analysis context >>> sc = pp.shortcircuit.create_analysis() >>> # create a bus fault on the first two buses >>> buses = n.get_buses() >>> sc.set_faults(id = ['fault_1', 'fault_2'], element_id = [buses.index[0], buses.index[1]], r = [1, 1], x = [2, 2]) >>> # perform the short-circuit analysis >>> # results = sc.run(n, pars, 'sc_provider_1') >>> # returns the analysis results >>> # results.fault_results
