Super-Capacitor based D-STATCOM applied in IEEE 13-bus industrial distribution system

This paper proposes a new control method for D-STATCOM (Distribution STATIC Compensator) applied in IEEE 13-bus industrial distribution system, that enables D-STATCOM to mitigate all types of fault. This paper validates the performance of D-STATCOM system to mitigate power quality problems and improve distribution system performance under all types of system related disturbances and system faults, such as Single Line to Ground (SLG), Double Lines to Ground (DLG) and Three Lines to Ground (TLG) faults. In this paper, the 12-pulse D-STATCOM configuration with IGBT is designed and the graphic based models of the D-STATCOM are developed using the PSCAD/EMTDC electromagnetic transient simulation program. As a case study, a 13-bus IEEE industrial distribution system is simulated to verify operation of proposed D STATCOM.
