Abstract

Static synchronous compensator (STATCOM) is a static compensator used to regulate voltage by reactive power injection, and to improve dynamic stability of power system. In this paper, the STATCOM control and operation for a 48-pulse VSC topology implemented with series connected transformers is reported. Two different control modes - voltage control and VAR control - for the STATCOM are investigated for a single STATCOM and dual STATCOM connected to a transmission bus. The two +100 MVAR (STATCOM) based on a full model comprising 48-pulse Gate Turn-off (GTO) thyristor based VSC is modeled. The control scheme for the STATCOM is fully validated by detailed simulations for a 2-bus power system. The VSC topology issues on the STATCOM control and performance are presented
