Modeling and Simulation of Distribution STATCOM

My dissertation presents a study on the modeling of a STATCOM used for reactive power compensation a distribution network. The power circuit of the distribution -STATCOM and the distribution network. Simulation performances obtained with modeling approaches are presented. Models of power circuit and control system have been implemented in the same Simulink diagrams. my dissertation investigates the operation of control scheme for Static Synchronous Compensator (STATCOM) based on a new full model comprising a 48-pulse Gate Turn-Off thyristor voltage source converter for combined reactive power compensation and voltage stabilization of the electric grid network. The STATCOM scheme and the electric grid network are modeled by specific electric blocks from the power system block set. The performances of STATCOM connected to the 230-kV grid are evaluated. The proposed control schemes for the STATCOM fully validated by digital simulation.
