Proposta de diretrizes para controle de tensão em sistemas de distribuição de energia elétrica

Abstract

This study is especially dedicated to determine the best way to operate equipment used related to power system voltage control, among them the transformers with tap changer and shunt capacitor banks. The Electric Power System, in order to fulfill its purpose of ensuring energy supply with quality and reliability, requires implementation of a broad and complex number of activities. The activities, which encompass tasks of expansion and operations, are contextualized, and include from elaboration of plans that aim to guarantee the future operation of the system, to real-time activities, performed in control centers. The purpose of this monograph is presented through guidelines for voltage control in electric power distribution systems. The methodology consists of applying the proposals for control in a systems real case, using the power flow program. The elaboration of the present study leads to a set of relevant findings and achievements. The proposed guidelines seek a better form of operation of the system equipment, providing a quality service to the final consumer, favoring the reduction of losses in the system and preservation of the own equipment involved.
