A solution to obtain precise fault location using a two-end data algorithm

In the paper there is presented a solution to improve the fault location precision using the actual measurements from the line ends. This solution improves the fault location for the lines where the one-end data fault location is implemented. In order to implement this solution first there are downloaded the voltage and current measurements from each end of the faulted line, then a manual synchronization of these measurements is applied and in the end the two-end data fault location solution is applied. The approach was tested with real data as well as with simulated data. The simulated data was obtained from a simulation equivalent model of the faulted grid. The results obtained demonstrate the precision of the proposed solution when compared with the results of the actual one-end data fault locators.
