Estudo de qualidade da energia elétrica e de análise de curto-circuito para complexo eólico

Abstract

With the great growth in the search for renewable energy, in Brazil, with its great energy capacity from these sources, the interest and growth of the Insertion of Wind Farms in the basic transmission network arose. Thus, studies of its consequences with respect to the electromechanical transient power flow, as well as the electrical transient, short-circuit levels, and energy quality, are essential. Currently, these studies are required by ONS (National Electric System Operator), through its current rules regarding the insertion of these new energy sources, such as the Delta do Parnaíba Wind Complex, which is analyzed in this work. Then, to carry out this study, the software ANAFAS and HARMZS will be used, in the academic version, and a compact electrical system (radial) with real data from the SIN network (Sistema Interligado Nacional). The results obtained show that, when inserting the Delta do Parnaíba Wind Complex in the electric grid, the harmonic distortion indexes will not be violated. In addition, it was analyzed that the appropriate equipment must withstand the levels of short circuits presented.
