Modelling and Simulation of 6

This paper presents the use of a 6-pulse Gate Turn Off (GTO) model of voltage source Synchronous Compensator (STATCOM) for reactive power compensation and voltage stabilization on electric network. The device is connected in shunt with the power system bus and is controlled by a controller. The complete STATCOM within a power system is performed in the MATLAB/Simulink environment using the Power System Blockset (PSB). The STATCOM Scheme and the electric grid network are modeled by specific electric blocks from the power system blockset The control system is based on Synchronous Reference Frame theory The performance of the selected ±100 Mvar STATCOM scheme connected to the 500-kV grid is evaluated. The operation of the STATCOM is validated in both the capacitive and inductive modes of operation. Reactive power compensation and voltage regulation is validated for load and system
