ElmSym attributesPowerFactory Synchronous Machine
Every attribute of the PowerFactory Synchronous Machine (ElmSym): 277 input parameters and 1317 result variables, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What ElmSym is
A synchronous machine, generator or motor. Reactances, time constants and inertia sit in its type (TypSym); the element holds the dispatch, the control mode and the number of parallel machines.

Read and write ElmSym in Python
import powerfactory
app = powerfactory.GetApplication() # GetApplicationExt() from outside PowerFactory
app.GetFromStudyCase("ComLdf").Execute() # results exist after a calculation
for gen in app.GetCalcRelevantObjects("*.ElmSym"):
p_bus1 = gen.GetAttribute("m:P:bus1") # Active Power, MW
q_bus1 = gen.GetAttribute("m:Q:bus1") # Reactive Power, Mvar
print(gen.loc_name, p_bus1, q_bus1)
gen = app.GetCalcRelevantObjects("*.ElmSym")[0]
gen.SetAttribute("pgini", 120) # dispatch 120 MW- A result at a terminal of the synchronous machine needs the terminal in its name:
m:P:bus1, notm:P, which raisesAttributeError. - 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.
