Hello, I'm using PSS/e ver 33. And when I run simulation, the curve in the plot doesn't start from 0s. I don't know how to solve this problem. Please help me with this, I've been facing it for a long time. Thank you!
I believe you are changing the output file name during the dynamic simulation. I give an example below:
psspy.strt_2([0,1],r"""file2""")
psspy.run(0, 0.5,0,1,0)
psspy.dist_bus_fault(151,1,0.0,[0.0,-0.2E+10])
psspy.run(0, 0.6,0,1,0)
psspy.change_channel_out_file('file3')
psspy.dist_clear_fault(1)
psspy.run(0, 2.0,0,1,0)Here, the API change_channel_out_file changes the name of the output file at t=0.6 s.
The resulting plot of output file2.out is:
I.e., file2.out only contains the results up to t=0.6 s.
File file3.out contains the simulation results from time t=0.6 and the plot is shown below:
The output file name shall be defined at strt and not changed during the simulation. So, make sure API change_channel_out_file is not used in your code.
You are absolutely correct. And if file 1.out was saved in the snapshot file, reusing the snapshot file to continue the simulation will pickup where we left off in the previous run.
Did you import your dynamic file from a .dyr file or a .snp file? If from a .snp file then your initial starting point was saved at a location other than 0s after initialization.
I did create new .dyr and .out files, but the results didn't change.
I need to look at your simulation script to better assist you or tell me axactly step by step of how you initialized your model.

Where does your curve start?
It starts from t = 1s
