unbalanced fault simulation in psse33
Hi folks, when I do unbalanced fault simulation such as 1 phase fault and so on in PSSE ,It was failed to add fault,who can help me how to do it,thank you

If you do not have any information on the sequence impedance, it would be impossible to determine.
If you do have the Thevenin sequence impedance at the particular bus you are applying a fault (and let's say not for anywhere else in the network), you can emulate a bolted single-phase fault by setting the impedance value to the sum of the negative and zero sequence components of the Thevenin impedance, and apply a three-phase fault.
hello I thanks that your simulation model is wrong (verify if you have the sequence data).

bus-3001 to bus-3003 unbalanced fault in official file 'savnw' cannot be added successfully.

Make sure you have sequence data.
Your are right ! Because i a beginner so there not have the sequence data
