Abstract :
Thyristor Controlled Series Capacitor (TCSC) has been used for various purposes such as power system stability improving and increasing of loadability, loss reduction, line impedance compensation or power flow control. Fast switching of TCSC from capacitive mode to inductive mode and vice versa following the fault and clearing of it respectively, is an essential key for improving transient and even dynamic stability of power system which have not been considered significantly. In this paper a new algorithm for fast mode-switching and control of TCSC in less than half cycle is proposed for changing capacitive to inductive mode and vice versa in less than half cycle. Simulation results show that the proposed method is faster and more reliable in different conditions than the existing method and can be used more effective in transient and dynamic stability improvement.
