One of the most important modules on the distribution management system (DMS) is the fault location framework, which requires an effective algorithm to identify the fault line channel from the data provided by different intelligent electronic devices (IEDs). The accuracy of this process leads to smart features of intelligent network monitoring and efficient isolation. This paper proposes the algorithm core of a fault locator software, based on undirected Dijkstra implemented in MATLAB, and co-simulated in three standard feeders systems with distributed generation using DSSim-PC and integrated in LabVIEW as a whole framework of a fault location manager.
