A Matrix Algorithm Roughly Approach to Distribution Network Fault Location Based on Fault Complain Calls Information

The problems existing in current fault location for distribution network are analyzed. According to the structure of a certain distribution network and matrix algorithm, a new method for fault location in distribution network is presented by using the fault complain calls, and a feasible criterion is put forward by which the fault occurred in distribution network can be located. In this method the trivial calculation is not necessary. So not only the time for fault location and isolation can be greatly shortened, but also the objectivity of the rules can be ensured.While the information of complain calls is imperfect and the communication of distribution automation system is lost, because of the good fault tolerant performance of the proposed method, the fault location can still be finished quickly and accurately. The simulation and calculation of the fault occurred in a distribution network consisting of single source and multi-outgoing lines is carried out. The result shows that the method is simple and effective.
