Abstract

DSTATCOM can compensate voltage sags by injecting the reactive power into the distribution system; however, the false compensation due to the interaction with system could occur. In this paper, the design considerations of DSTATCOM for voltage sag compensation have been studied. The voltage sag compensation performance with different current injection schemes is briefly explained and the interaction is described. Then, the design of DSTATCOM system and controller for voltage sag compensation is proposed. Simulation results confirmed that the proper design of DSTATCOM system can achieve the good voltage sag compensation performance without interaction with the system.
