master:excac_2016 parametersPSCAD Type AC Exciter
Every parameter of the PSCAD Type AC Exciter (master:excac_2016): 253 names, with the unit, the default and the meaning PSCAD gives each one. Copy a name into parameters().
What master:excac_2016 is
Type AC Exciter (Type AC Exciter IEEE Std. 421.5-2016), a component of PSCAD's Master Library, filed under machines, exciters and governors.
- Definition
master:excac_2016- PSCAD name
- Type AC Exciter
- Category
- Machines, exciters and governors
- Parameters
- 253, in 21 groups; 224 carry a unit
- Read from
- PSCAD 5.0.0, 2026-11-07
Read and write master:excac_2016 in Python
import mhi.pscad
pscad = mhi.pscad.connect() # the PSCAD that is open; launch() starts one
project = pscad.project("my_case") # a case loaded in the workspace
for comp in project.find_all("master:excac_2016"): # the exact definition, namespace first
params = comp.parameters() # every parameter, as PSCAD holds it
print(str(params["EFDN_3"])) # Efd Value at which KF Changes [EFDN], in pu
comp = project.find_all("master:excac_2016")[0]
comp.parameters(EFDN_3="4.72 [pu]") # a value that carries a unit is written with it- A parameter is named exactly as in the table, letter case included:
parameters()gives every one of them in a dictionary, and a name the component does not have is refused. - A value that carries a unit comes back as a number whose unit is only in its text, so read it as text first (
str(...)) or the unit is lost. PSCAD keeps a written unit as it is given:"2500 [mohm]"stays in mohm. - A Choice is read and written as its symbol (the capitals in "Written as"), not as the words PSCAD shows in the dialog.
find_all()takes the exact definition only. A wildcard or a bare name withoutmaster:comes back empty; the Builder'spx_findwalks the pages for those.
The Builder's runtime does the same with the unit handled for you: px_get(comp, "EFDN_3") and px_set(...), which also records the old value so the case is put back at the end. Getting started shows them.
