Abstract :
This paper proposes a new control method for D-STATCOM (Distribution STATIC Compensator) control system. The operation of this proposed control method enables D-STATCOM to mitigate all types of fault, intelligently (such as Single Line to Ground (SLG) fault and Double Phase to Ground (DPG) fault and three-phase fault). In this paper, the 12-pulse D-STATCOM configuration with IGBT is designed and the graphic based models of the DSTATCOM are developed using the PSCAD/EMTDC electromagnetic transient simulation program. This paper validates the performance of a D-STATCOM system for improving distribution system performance under all types of fault. The reliability and robustness of the control scheme in the system response to the voltage sags caused by SLG and DPG and three-phase faults is obviously proved in the simulation results.
