ElmFile attributesPowerFactory Measurement File
Every attribute of the PowerFactory Measurement File (ElmFile): 15 input parameters and 172 result variables, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What ElmFile is
A measurement file: it reads a time series from a file and feeds it into a simulation as a signal.
- Class
ElmFile, element class- PowerFactory name
- Measurement File
- Attributes
- 15 input parameters and 172 result variables, in 5 calculations
Read and write ElmFile in Python
import powerfactory
app = powerfactory.GetApplication() # GetApplicationExt() from outside PowerFactory
for obj in app.GetCalcRelevantObjects("*.ElmFile"):
print(obj.loc_name, obj.GetAttribute("loc_name")) # Name
obj = app.GetCalcRelevantObjects("*.ElmFile")[0]
obj.SetAttribute("outserv", 1) # switch it off- An input parameter is read and written with or without its
e:prefix:GetAttribute("outserv")andGetAttribute("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.GetAttributeafter a run gives the value at the last time step.

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