Abstract

The structure of distribution network is complex, and multi-hybrid power lines such as wires and cables are used, which cause difficulties in accurate determination of fault distance. A new method to pinpoint faults was provided by this paper. The fault branch was located with the logic operation of the status information provided by the disconnect switches and wiring fault indicators, and the fault distance was accurately calculated by the impedance method. In this method, the equations were written, in which the fault point and fault positive sequence voltage were treated as the unknown quantity, and the fault distance was calculated by solving the equations. Simulate with ATP, and the data was processed with MATLAB to verify the feasibility of the algorithms in complex distribution network fault location. The results show that the location method has a good localization accuracy.
