Abstract :
In this paper, a control scheme for a novel capacitive-coupled STATCOM in three-phase power system is proposed and analyzed. In order to maintain the dc-link voltage to a constant level, an active block diagram model is built. Based on this model, a novel dc-link voltage feedback control scheme is proposed and discussed. The proposed novel capacitive-coupled STATCOM is characterized by lower the dc-link rating of the conventional inductive-coupled STATCOM with good system compensation feature. Simulation results are given to prove the effectiveness of the control scheme together with the dc-link voltage feedback control in the novel capacitive-coupled STATCOM.
