Estudo de caso: comparação pré-operação e pós operação de indicadores de campanha de qualidade de energia elétrica em usinas de geração de energia renovável

Abstract

According to ONS documentation “Procedimento de Rede” chapter 2.8, whenever happens a solicitation to access power grid, it is necessary to run a series of power quality analysis, measuring, mostly, voltage harmonic distortion, voltage unbalance and voltage flicker. This measurement series is called Quality Campaign and need to occur in pre-operational and post operational steps. When Eolic or photovoltaic complexes requests power grid access, it is necessary to measure, along with the other indicators, the current harmonic distortion, due to nonlinear load. This particularity makes Eolic and Photovoltaic complexes Quality Campaign different from others. The objective of this project is to present a comparison between power quality indicators pre-operational and post operational steps in five different power plants.
