A hybrid method to determine the short-circuit location on medium-voltage network: Simulation and measurement

Abstract

In order to improve stability and power quality of the system, there is an essential role in the rapid detection of grid malfunction, particularly in grids with difficult geographical conditions. This article introduces a method which could quickly delineate short-circuit fault location by establishing the corresponding matrix between nodes on grid and short circuit current value. A 50-nodes local medium-voltage network is calculated. The modeling results will be compared to the value of measurement.
