Read and write TypTr2 in Python
import powerfactory
app = powerfactory.GetApplication() # GetApplicationExt() from outside PowerFactory
# Types live in the equipment library of the project.
types = app.GetProjectFolder("equip").GetContents("*.TypTr2", 1)
for typ in types:
print(typ.loc_name, typ.GetAttribute("strn")) # Rated Power, MVA
# An element points to its type with typ_id; t: reads a type value through the element.
for trafo in app.GetCalcRelevantObjects("*.ElmTr2"):
print(trafo.loc_name, trafo.typ_id.loc_name, trafo.GetAttribute("t:strn"))
types[0].SetAttribute("strn", 200) # rated power 200 MVA: every element of this type changes- An input parameter is read and written with or without its
e:prefix:GetAttribute("outserv")andGetAttribute("e:outserv")give the same value. - A type is shared: a change to it changes every element that uses it. Read a type value through an element with the
t:prefix.
TypTr2 input parameters
The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
