Due to the arising liberalization and deregulation of the electric energy market, the demand on AC-transmission system are steadily growing. Therefore, more sophisticated ac-system controllers are highly needed. This paper is focusing on one of these topologies, i.e the two-levels voltage source inverter static compensator (Statcom), which is an interesting high power circuit for transmission applications. A steady state and transient stability models with GTO thyristors are proposed. Simulations are carried out in a 9 bus, 3 machines AC system. The proposed model is suitable for power system studies that require accurate representation as transient stability and voltage stability.
