I am using psspy to run transient analysis on a huge network. I am storing the voltage and angle snapshot of every bus at every 40 millisecond. At some time instant I want to apply an asymmetrical fault at one line in a particular phase (say, LG fault at phase B of the line between bus IDs 201 and 202). I want to store the transient disturbances (voltage and angle at all the buses) arising from that.

I have tried using the modules like SCMU etc. which seem to give the data of just the steady post-fault values. Also, modules like dist_scmu_fault_2 do not seem to work on my system and shows an error: module not found.

C:\fakepath\asymfault.png The attached file is a py script file that will simulate your asymmetric fault definition.

I used the recording option in PSSe v 33.9 and it came out with dist_scmu_fault

Once downloaded, rename it from*.png to *.py

This is what I did too. However the LG fault is always applied at phase A in this case. How to apply it on other phases?

PSSe models a positive sequence network, therefore values for asymmetric fault at Phase A are the same as for Phase B or C.
