TypAsm attributesPowerFactory Asynchronous Machine Type - old
Every attribute of the PowerFactory Asynchronous Machine Type - old (TypAsm): 60 input parameters, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What TypAsm is
An asynchronous machine type in its older form: ratings, impedances and the torque characteristic of an induction machine.

Most used TypAsm attributes
| Attribute | Unit | Description | Where |
|---|---|---|---|
sgn | kVA | Rated Apparent Powerrated power, kVA | input data |
ugn | kV | Rated Voltage | input data |
aiazn | p.u. | Locked Rotor Current (Ilr/In)locked rotor current | input data |
tag | s | Acc. Time Constant | input data |
xm | p.u. | Mag. Reactance | input data |
xdss | p.u. | Locked Rotor Reactance | input data |
rstr | p.u. | Stator Resistance | input data |
Read and write TypAsm 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("*.TypAsm", 1)
for typ in types:
print(typ.loc_name, typ.GetAttribute("sgn")) # Rated Apparent Power, kVA
# An element points to its type with typ_id; t: reads a type value through the element.
for motor in app.GetCalcRelevantObjects("*.ElmAsm"):
print(motor.loc_name, motor.typ_id.loc_name, motor.GetAttribute("t:sgn"))
types[0].SetAttribute("ugn", 6.6) # rated voltage 6.6 kV: 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.
TypAsm input parameters
The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
