A New Double-Ended Fault-Location Scheme for Utilization in Integrated Power Systems

A new double-ended algorithm for fault location in an integrated power system (IPS) is presented. This method can be applied to real-time fault location because of its simplicity and its ability to self-synchronize. Experimental tests have been undertaken on both ac and dc power systems and both hard (step) faults and restriking transient faults (bouncing faults) have been investigated. The method is also shown to work in the presence of nonlinear loads. The performance of the proposed algorithm has been compared with a common synchronized double-ended fault-location method.
