Active Power Quality Controllers

Abstract

Dynamic Static Synchronous Compensator is the most important controller for distribution networks and probably in SEEN. It has been widely used since the 1990s to regulate system voltage precisely, improve voltage profile, reduce voltage harmonics, reduce transient voltage disturbances and load compensation. Rather than using conventional capacitors and inductors combined with fast switches, the D-STATCOM uses a power-electronics converter to synthesise the reactive power output. A D-STATCOM converter is controlled using PWM or other voltage/current-shaping techniques. D-STATCOMs are used more often than STATCOM controllers. Compared to STATCOM, D-STATCOMs have considerably lower rated power and, in consequence, faster power-electronics switches; thus the PWM carrier frequency used in a distribution controller can be much higher than in a FACTS controller. It has a substantial positive impact on the dynamics of the D-STACOM.
