Análise da qualidade de energia de sistemas fotovoltaicos conectados à rede de distribuição em baixa tensão

Abstract

This paper deals with the quality of electric power connections present in Photovoltaic Systems to Distribution Network of Dealers. One of the essential equipment for this connection is the inverter. To deliver power to the grid, the inverter injects a waveform of current in theory should perform purely sinusoidal, but due to the wide variety of technologies inverters and the percentage of power being injected into the network in relation to its nominal power , this current has a certain level of distortion. Likewise for the sine wave voltage, the quality of both the inverter as the mains where the inverter is connected, have a significant impact on the quality of the voltage wave inverter. Currently has very few facilities of this nature operating in Brazil, which makes further analysis of their behavior. With the publication of the module 8 PRODIST and Normative Resolution No. 482/2012, both by ANEEL, has been a major breakthrough in this area, allowing the interest in this connection model is expanded and rules feasible and clear to all interested in the subject. The search for the identification of factors that may affect or preclude the connection or the performance of Photovoltaic System with Network Connection in Brazil, it is extremely important for this generation source is not just a future promise to diversify the Brazilian energy matrix .
