How can i set the fualt location in PSS/E

asked Aug 14 '4

Could I ask for some assistance? I am working on simulations in PSS/E software and have encountered some difficulties with branch faults. I am curious if it's possible to set the fault location at specific points along the branch, such as 20%, 40%, or 60%,and so on. If so, how can these locations be set? Additionally, if this setting is feasible, I would like to generate simulation samples in bulk using a Python API. How should I invoke the commands to set the fault location in my Python program? If anyone has knowledge in this area, could you please offer some guidance or help? Thank you very much!

Sorry I'm not familiar with branch fault, but I do check about the setting, you could check "Dynamics/ Disturbances/Calculate and apply branch unbalance" which mentioned about "Fault location as a fraction of line". But I have no experience using this function. Hope this comment can help!

Use API dist_spcb_fault_2 to simulate an unbalanced in-line fault.

When I apply unbalanced in-line fault, my PSS/E appears a error box: Messages for api DIST_SPCB_FAULT_2 No sequence data in memory. So,sorry for consulting you that what can i do.

You need sequence data for the case to perform unbalanced faults. For a three phase in-line fault without sequence data available, use the method proposed by @PH-profile.

You can add a dummy tap bus along the line with a specific percentage and apply a bus fault at that point.

I'm sorry that my knowledge of PSS/E software is too shallow, and I don't know how to implement the method you proposed. Could you please provide the corresponding python program? It is really very troublesome.
