VOLTAGE SAG COMPENSATION USING DISTRIBUTION STATIC COMPENSATOR (DSTATCOM)

International Journal of Advances in Signal and Image Sciences, 2015
Distribution Static compensator (D-STATCOM) is employed to solve the sag problems in this paper. In order to operate a four wire DSTATCOM in voltage control mode, it requires a reference voltage. To generate the required reference voltage, a new schematic algorithm is developed. It ensures Unity Power Factor (UPF) at different load and fault conditions,
