| Abstract: | The problems exiting in current fault location algorithms for distribution networks are analyzed. Based on the improved matrix algorithm and according to the end faults occurred in distribution network and the multiple faults occurred in different lines, a feasible criterion is put forward by which not only the single fault occurred in distribution network can be located, but also the end faults and the multiple faults can be quickly and accurately diagnosed. The simulation and calculation of various faults occurred in a distribution network with three sources and the faults occurred in a distribution network consisting of single source and multi-outgoing lines are carried out. The calculation results show that the presented criterion is effective. |
