Abstract:
This paper presents the application of Clonal Algorithm technique for detection of Voltage Sags and Swells with few meters, in order to monitor short-circuit conditions occurring in the electrical network. It is considered possible conditions of symmetry. These conditions make the problem even more complicated. All the proposed method steps are described, from the construction of the antibodies, cloning, mutation of clones, maturation, to the selection of novel antibodies. The algorithm starts with a large number of monitors, and then decrease this number to find a configuration with a minimum number of monitors that ensure monitoring of all short-circuit conditions. The evaluation of the methodology performance for the 63-buses network is presented.
