ElmCabsys attributesPowerFactory Cable System

Every attribute of the PowerFactory Cable System (ElmCabsys): 59 input parameters and 136 result variables, with units and meaning. Copy a name into GetAttribute or SetAttribute.

What ElmCabsys is

A cable system: several cables laid together, with the coupling between their cores and sheaths.

Read and write ElmCabsys in Python

import powerfactory

app = powerfactory.GetApplication()          # GetApplicationExt() from outside PowerFactory

for obj in app.GetCalcRelevantObjects("*.ElmCabsys"):
    print(obj.loc_name, obj.GetAttribute("loc_name")) # Name

obj = app.GetCalcRelevantObjects("*.ElmCabsys")[0]
obj.SetAttribute("outserv", 1)                # take it out of service
  • An input parameter is read and written with or without its e: prefix: GetAttribute("outserv") and GetAttribute("e:outserv") give the same value.
  • RMS and EMT variables change over time: record them in a results object (ElmRes) to read the whole curve. GetAttribute after a run gives the value at the last time step.

ElmCabsys input parameters

The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
