master:Zintegral parametersPSCAD Integrator
Every parameter of the PSCAD Integrator (master:Zintegral): 10 names, with the unit, the default and the meaning PSCAD gives each one. Copy a name into parameters().
What master:Zintegral is

Read and write master:Zintegral 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:Zintegral"): # the exact definition, namespace first
params = comp.parameters() # every parameter, as PSCAD holds it
print(str(params["T"])) # Time Constant, in s
comp = project.find_all("master:Zintegral")[0]
comp.parameters(T="0.002 [s]") # 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, "T") and px_set(...), which also records the old value so the case is put back at the end. Getting started shows them.
