Resumen
This work analyzes a voltage regulator applied to low-voltage single-phase distribution networks, especially long distribution rural distribution lines with problems to comply with voltage level standards. This voltage regulator is classified as D-STATCOM (Distribution Static Synchronous Compensator), since it is composed of a single-phase PWM inverter connected in parallel with the point common coupling through a second-order LC filter, composing a third order circuit (LCL circuit) with the line inductance. A digital control system is proposed for the D-STATCOM in this dissertation, composed of three voltage loops: the damping, the control loop of the AC voltage, which controls the voltage supplied by the regulator control loop and the DC voltage control loop, responsible for regulating the DC bus voltage. Moreover, a full-state feedback controller is used to achieve active damping of the LCL filter resonance. Finally, experimental results are presented to demonstrate the efficiency of the proposed control system
