“…For this reason, the author of the paper uses clustering techniques to divide acquired data into groups that reflect operating conditions. In work [8], a technique based on graphical cluster analysis was developed to be implemented in a smart power quality analyzer, to monitor electrical networks. In the presence of a fault, the equipment starts the measurement procedure and higher order statistics are calculated in the time domain to allow classification.…”

“…In articles [7][8][9][10][11][12][13][14][15][16][17], clustering techniques are used for purposes different from the objective of this paper, such as monitoring, identification and classification of events, location of the source and pattern recognition of voltage sags. These references were presented to identify the application of cluster analysis in the power quality area.…”

This paper proposes a methodology for establishing base values for short-term voltage variation indices. The work is focused on determining which variables best describe the disturbance and based on that, establish clusters that allow a more adequate definition of base values for the indices. To test the proposed methodology, real data from 19 distribution systems belonging to a Brazilian electricity utility were used and consequently the index presented in the country standard was considered. This study presents a general methodology that can be applied to all distribution systems in Brazil and could serve as a guide for the regulatory agencies in other countries, to establish base values for their indices. Furthermore, the objective is to show through the results that, with the database used is possible to establish clusters of distribution systems related to the voltage sag and with these establish a base impact factor, distinct for each distribution system.
