TypLod attributesPowerFactory General Load Type
Every attribute of the PowerFactory General Load Type (TypLod): 48 input parameters, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What TypLod is
A general load type: how a load's P and Q change with voltage and frequency (the exponents and coefficients of its static model) and its dynamic share.

Read and write TypLod 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("*.TypLod", 1)
for typ in types:
print(typ.loc_name, typ.GetAttribute("kpu")) # Exponent e_cP
# An element points to its type with typ_id; t: reads a type value through the element.
for load in app.GetCalcRelevantObjects("*.ElmLod"):
print(load.loc_name, load.typ_id.loc_name, load.GetAttribute("t:kpu"))
types[0].SetAttribute("kpu", 2) # voltage exponent e_cP of P: 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.
TypLod input parameters
The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
