Estudo de viabilidade técnica do uso de D-Statcom para a regulação de tensão em linhas de distribuição rurais

Abstract

This work presents a technical feasibility study of the use of the D-Statcom compensators in low voltage rural distribution networks. In order to reach this objective, basic concepts about the parameters and powers in the electric systems are presented, as well as mathematical models to analyze the behavior of the voltage due to parametric variations of loads and distribution network. It also presents modeling and analysis with the insertion of the compensator in the electrical system under study, mainly to evaluate the capacities and limitations of the device, as well as the main parts that compose it. In order to control the voltage level, control loops are designed from the plants, it is mentioned that the resonant proportional controller is designed for alternating current loops and the integral proportional control for continuous current loop. Finally, simulations are performed to evaluate the design, as well as to certify the viability of reactive compensation in distribution lines.
