I am looking to evaluate the con data of plant models in dynamic file and I would like to be able to return this to a variable and if it is wrong then, use the function "changeplmodcon()"
Take a look at the answer to this post: https://psspy.org/psse-help-forum/question/656/accessing-model-index-values-eg-var-nums-from-python/
After seeing what you actually want to do, try something similar to the following:
#THIS CODE WILL SET THE CON(J+5) TO 0.0 IF THE VALUE OF THAT CON IS GREATER THAN 0.0
# FOR ALL GENROU MODELS IN THE CASE
#MODIFY BSYS TO A DEFINED SUBSYSTEM IF YOU DON'T WANT TO RUN ON ENTIRE CASE
BSYS = -1
ierr, buses = psspy.amachint(BSYS,4,'NUMBER')
ierr, ids = psspy.amachchar(BSYS,4,'ID')
for i in range(len(buses[0])):
ierr, model_name = psspy.mdlnam(buses[0][i],ids[0][i],'GEN')
if ierr:
continue
#CHANGE 'GENROU' TO WHATEVER MODEL YOU ARE LOOKING FOR
if 'GENROU' in model_name:
ierr, con_index = psspy.mdlind(buses[0][i], ids[0][i], 'GEN', 'CON')
ierr, con_num = psspy.mdlind(buses[0][i], ids[0][i], 'GEN', 'NCON')
cons = []
for i in range(con_num - 1):
ierr, con_val = psspy.dsrval('CON', con_index + i)
cons.append([con_index + i, con_val])
#NOT REALLY SURE WHERE YOU ARE GOING TO TAKE THIS, BUT YOU COULD DO SOMETHING LIKE THIS:
if cons[5][1] > 0:
NEW_VAL = 0.0
psspy.change_con(cons[5][0],NEW_VAL)
I have no idea what you are planning on doing with this, but hopefully this code will help out a bit. I found the 'dsrval' command in the API, so parsing wasn't necessary. to change the con, use the 'change_con' command.
@Yagna Without writing your own script to do so, I don't think so. I would think it would be pretty easy to write a regex parser to put the data you want into arrays though. Also, does this need to be after the dynamics data has been loaded into your case? Couldn't you just do your validation...
@EBahr I am very new to python and not quite familiar with regex parser. I have thousands of generator data that I would like to verify and the dyr file is very huge and contains every possible model for tens of thousands of machines. I just want to pick the generators of few model types and
verify. I could find all the right tools and functions for this purpose except for the "data retrieval" part. So could you give me an example code to parse the output of dlst so that a 2D array with [CON no., CON val] can be created. That would be very helpful! or any other suggestion.
