Modelagem e análise de reguladores de tensão em simulações de uma rede de distribuição de energia elétrica no software OpenDSS

Abstract

This work presents the modeling and performance analysis of single-phase voltage regulators connected in different topologies (wye, closed delta, and open delta) applied to a real medium-voltage distribution system (13.8 kV). Scenarios were developed with balanced loads, unbalanced loads, and the insertion of photovoltaic distributed generation, in order to evaluate the behavior of the devices under different operating conditions, including reverse power flow situations. The adopted methodology allows observation of the voltage behavior along the feeder, the individual response of the regulator Taps, and the impact of the adopted configuration on phase balance and voltage magnitude. The results analysis contributes to the technical and operational understanding of the effects of topological choices for regulators in modern distribution networks and reinforces the usefulness of OpenDSS as a decision-support tool in electrical engineering projects.
