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,

Implementation of four‐leg distribution static compensator
IET Generation, Transmission & Distribution, 2014 An implementation of a four‐leg distribution static compensator (DSTATCOM) using an adaptive neural network‐based control algorithm for compensation of linear/non‐linear loads using voltage source converter is presented here. The proposed control algorithm, which is based on adaptive neural network, is used for extraction of fundamental active and ...
