if fault == 'LL':
psspy.dist_scmu_fault([1,1,2,bus],[0.0,0.0,-0.2E+10,-0.2E+10])
elif fault == 'LLG':
psspy.dist_scmu_fault([1,1,2,bus],[0.0,0.0,0.0,0.0])
I read API manual(Section 4.13.12) and set parameters like this for LLG and LL fault. But I'm not sure if it is correct because the difference between the curves I plot for voltage and angle is not so obvious..Could anybody check if these parameters are correct?
The parameters seem to be correct. Please note that zero sequence network must be present in the saved case when simulating ground faults with distscmufault. LG and LLG faults cannot be calculated if zero sequence data is missing in the saved case.
Since you get same results with LL and LLG I suspect that you have not entered zero sequence data for your network. You are simulating LL fault in both simulations!
Thank you so much for your reply..But I use "psspy.check_sequence_data(0,1,0)" to check my sequence data and PSSE replies that I have added sequence data :(
