Abstract :
DSP-based implementation of a 3-phase static compensator (STATCOM) is presented. The closed-loop control scheme of the compensator is based on fuzzy logic. The hardware module of an IGBT-based PWM current-controlled voltage-source-inverter (PWM-CC-VSI) is taken as a STATCOM. Two different types of current control techniques, namely, direct and indirect current control are designed for the compensator. The experimental tests on the compensator are carried out with both techniques. The STATCOM is tested as an active filter (AF) to select the most promising technique for the current control
