I would like to transform a branch form in-service to out-service using Python.
It is not mean to remove the branch.
So, I tried to do that using following code and then saved the result.
psspy.branchchng(Fromnum , To_num , ID ,intgar1=0)
But, I got a raw file to reomve the branch
Could you inform me the solution?
If I understands your question correctly, assuming you want to use the PSSE API python method to take a branch out of service in the powerflow model.
Here's the standard python syntax per PSSE_API document - i = frombus, j = tobus, ckt = circuit id, intgar is an array of 6 elements, so using the keyword function, intgar1 is where the branch status can be set from 1 to 0 where 1 = in service.
psspy.branchdata3( i=12345,j=34567,ckt = '1',intgar1 = 0)
It is better to use branchchng since that API will only act on existing branches. API branchdata_3 will add a branch if the branch does not exist. It is not necessary to give the keywords since all needed argument are in the correct order, i.e.
psspy.branch_chng(12345,34567,'1',0)agreed -the keyword function is just my personal preference - I tend to forget what those values represent after a period of time.
