Abstract

The double-ended impedance-based fault location Method (DEFLM) uses the wideband frequency content of the transient generated by the fault to determine the impedance from the point of measurement to the fault. This work evaluates the use of DEFLM in integrated power system such as those in More Electric Vehicles. Two approaches have been investigated with two measurements from two terminals and with one reduced measurement. The outcomes demonstrate that the DEFLM with full measurements provide a very high accuracy of the fault location with accuracy reaches 99% assuming the two end measurements are synchronized. On the other hand, the DEFLM with reduced current measurement from loads end shows less accuracy as the fault reaches the load terminal. However, the accuracy still high and within acceptable range utilizing more cost-effective approach.
