    A Practical Integrated Fault Location Technique for Radial Power Distribution Systems
    (IEEE, 2019) Hamadouche, Tarek; Bendjeghaba, Omar; Ahriche, Aimed
    power distribution systems (PDS) are becoming more complex and dispersed at long distances and different locations. With its radial and several laterals configuration, loads could be connected at similar distances from the substation which leads to a multi estimation of fault location and consuming more time for iterative fault location algorithms. In order to overcome those difficulties, a practical integrated fault location method for radial PDS is presented in this paper. The basic idea of the proposed approach is to partition a multi lateral distribution system to possible mono lateral system (MLSs) by a proposed communicant sensor (CS). Then an impedance based algorithm is applied only at the faulty MLS. To examine the whole method in the field, a real PDS from the Algerian distribution grid is used. Experimental results present significant benefits compared to a previous method reported in the literature.

    A distributed monitoring scheme for a fleet of UAV flying drones
    (2022) Nouasri, Amine; Riahla, Mohamed Amine
    In this paper, we present a solution that would allow members of a unmanned Arial vehicles (UAV) drone fleet to cooperate with each other in order to monitor the network regarding incidents that could compromise security or impact service continuity during their mission. The proposed work implements a scheme to allow each drone to monitor the activity of immediate neighbours without a central control authority, and share that information. This is in order to decide of an action in case of a security incident or a degradation of their service has occurred. The purpose is to allow the network to be resilient and adopt itself to insure service continuity. The method we used allow the detection of incidents without the use of complex security and routing solutions, or the need to communicate back and forth with a central control authority. Our method uses four parameters to insure service continuity in the network: link quality, forwarding rate, checksum rate and mobility coordinates. This is to allow the detection of multiple incidents using the same scheme.
