Abstract:

Thyristor Controlled Series Capacitor (TCSC) as a dynamic system, similarly its ability in increasing power allocation in transmission lines, can be used to advance different power system problems. TCSC’s dissimilar advantages can be categorised as steady-state and transient ones. During a fault, TCSC can increase power quality by reducing the current and benefit to retain the voltage as high as possible. In this paper, the application of TCSC to improve one of the vigorous power quality issues, i.e., voltage sag is examined. Dissimilar operating modes of TCSC have different impacts on the voltage of the bus that the line equipped with TCSC is connected to. Repositioning to bypass mode upon appearance of a fault is a important feature of TCSC to advance voltage sag. The simulations on a trial network reveal these facts.
