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