Konferensbidrag (refereegranskat)abstract
- This paper focuses on fault analysis of a distribution feeder which employs Solid State Transformers (SSTs) rather than magnetic transformers in order to facilitate large scale integration of Distributed Energy Resources (DERs) into the system. To estimate the fault current profile on such a feeder, the paper proposes a new method which extends the capability of conventional short-circuit analysis method. Performance of the proposed method has been assessed by simulations on a sample distribution feeder.

- Fault current profile on a PV dominated distribution feeder is rather different than a conventional feeder. To estimate the fault current profile on such a feeder, the paper proposes a new method which extends the capability of conventional short-circuit analysis method. The paper also shows that this time varying fault current profile makes it also more difficult to estimate the time it will take for an overcurrent relay/device to interrupt such a fault current. The paper proposes a method for estimation of this operating time also. Performance of the proposed methods has been assessed by simulations on a sample distribution feeder.
