Abstract :
STATCOM is the state-of-the-art reactive power generator of power systems. This paper presents a novel reactive current detection and control strategy for STATCOM, under unbalanced and distorted supply voltages. To obtain accurate control, several compensation methods are proposed, such as phase-lag compensation, dead-time compensation and control-delay compensation. Finally, a 10 kVA STATCOM based on digital signal processor TMS320F2812 is investigated, and experiment results validate the proposed methods in this paper.
