Campanha de medição da QEE em função do acesso de fontes não lineares à rede elétrica: um estudo de caso.

Abstract

Currently the power grid is increasingly filled by new generation sources, many of them with non-linear characteristics. Distributed generation, wind and solar sources are of particular concern to the regulatory and supervisory bodies of the electricity system. It is known the contribution of non-linear sources with disturbances of the power quality, which can generate immense expenses with burning and malfunction of the system equipment, in such a way to exist a series of requirements for the entrance of these sources to the electrical system. In this sense, this work has the objective of analyzing measurement campaigns of power quality in distribution systems, one of the steps for the entry of non-linear loads or sources to the system, describing the recommendations, analyzes, steps and results obtained with these measurements. All analyzes are done following the recommendations of the National Electric Energy Distribution Procedures (PRODIST) and Network Procedures (PROREDE).
