Description
Summary:This paper proposes a digital control system for a voltage-controlled D-STATCOM applied to single-phase low voltage distribution networks. This system is especially suited for long rural distribution lines with problems to comply with voltage levels standards. The voltage regulator consists of a single-phase voltage-source PWM (Pulse Width Modulation) inverter connected in parallel with the point of common coupling (PCC) through a second-order low-pass filter. The proposed control system is composed of three loops: an active damping loop, a control loop to regulate the PCC voltage and a dc bus voltage control loop. Experimental results are included to demonstrate the performance of the proposed system.
