COMISSIONAMENTO DE USINAS FOTOVOLTAICAS

Abstract

Because the increase in installations of photovoltaic plants proved by the release and standardization by National Electric Energy Agency (ANEEL-BR), there is a considerable growth of micro generators connected to the electric distribution network and the new companies that offer the service of project and installation. However, there is no sufficient of qualified professional’s quantity to this demand, which reduces the quality and efficiency of projects and facilities. The paper shows the photovoltaic plants commissioning based on the current Brazilians norms and was a case of study in a plant installed in the Cidade Universitária da Fundação de Ensino e Pesquisa do Sul de Minas (Unis MG) with 1,325 kWp of power. The commissioning is aimed at verifying the correct functioning of the plant components to ensure that it operates in satisfactory conditions, and examines too if the facilities are compatible with the project. This work describes the procedures that were performed and the equipment used during the commissioning, as well as present the results obtained in the evaluated plant. It also presents a report containing all the data of the plant, as well as, the nonconformities found and how to adapt them. During the inspections were observed several documentary problems, installation and sizing, which were reported and indicated solutions and / or adaptations for each one, this text also presents the risk management for analysis of the need not to install a protection system against atmospheric discharges conditions.
