Estudo para melhoria da tensão nos sistemas de distribuição em baixa tensão.

Abstract

The conventional methods for voltage level control are concentrated in medium voltage. In some case, they are not enough to correct the voltage on secondary grid of distribution. This work presents the problems related to voltage regulation at low voltage, conventional methods for voltage correction and a strategy for voltage control on the low voltage of the distribution grid and the implementation of a remote measurement system as a strategy for low voltage control, maintaining it in accordance with the required standards by the National Electric Energy Agency (ANEEL), based on Module 8 of the Procedures for Distribution of Electric Energy in the National Electric System (PRODIST), entitled Quality of Electric Energy. Voltage control is important to ensure the stability of the Electrical Power System and the good performance of the equipment installed in the distribution network and the customers connected to it, in addition to attend the current legislation and avoiding penalties. Based on the carried out analyses, it can be concluded that these methodologies are useful as effective strategies for voltage control on secondary grid of distribution.
