Advanced Edge-Cloud Computing Framework for Automated PMU-Based Fault Localization in Distribution Networks

The detection and localization of faults plays a huge role in every electric power system, be it transmission network (TN) or distribution (DN), as ensures quick restoration thus enhances the system’s reliability availability. In this paper, framework that supports phasor measurement unit (PMU)-based fault is presented. Besides making process detecting, localizing reporting to control center fully automated, aim was make viable also for DNs, which normally do not have dedicated fiber-optic connectivity at their disposal. quality service (QoS) PMU data transmission, using widespread long-term evolution (LTE) technology, evaluated conclusions evaluation were used development proposed edge-cloud framework. main advantages can summarized as: (a) performed edge nodes, bypassing communication delay availability issues, (b) potential packet losses are eliminated by temporally storing (c) since no longer centralized, but rather takes place locally edge, amount transferred during steady-state conditions significantly reduced.
