2015-03-31 07:36:01 -0500 | answered a question | Zero sequence impedance I manage to perform my power flow simulation as well as dynamic simulation. Just that when i want to apply unbalanced branch fault, this problem occurs: Branch has NO ZERO SEQUENCE IMPEDANCE. When i entered the zero sequence data, and i run again, it shows 'NO PATH TO GROUND'. still figuring out why |

2015-03-29 19:31:25 -0500 | asked a question | Zero sequence impedance When i want to apply branch unbalance, but it says invalid BRANCH HAS NO ZERO SEQUENCE IMPEDANCE. It's a 9bus system btw. Can anyone guide me? Thanks |
