Abstract
This paper presents the use of a new full 48 pulse GTO model of voltage source converter FACTS-STATCOM (Static Synchronous Compensator) for reactive power compensation and voltage stabilization on electric grid network. The device is a power electronic GTO converter connected in parallel with the power system bus and is controlled by a novel controller. The complete digital simulation of the 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 while the control system is modeled using simulink. The control system is based on a decoupled strategy using the direct and quadrature components of the STATCOM current. The performance of the selected ±100 Mvar STATCOM scheme connected to the 230-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 excursions.
