Calculation and analysis of voltage violation problem on electricity distribution networks

The approach of this paper it is about voltage conformity delivered to the final customer, on electricity distribution networks. Have obtained physical and electrical characteristics information from the network coming from the database of the electricity company. The study presents the process of voltages estimation in primary and secondary circuits wich estimation of indicators of voltage violation. The presented cases studies approach a statistical analysis of sampling campaigns of distributor, voltage level analysis of one feeder circuit, the estimative of indicators of voltage violation and simulation validation with field measurements on the circuit. Through the found results it is possible to make better decisions of action to be taken and point out the circuit who needs maintenance.
