This paper presents the results of experimental study on the effects of synchronization systems for a thyristor controlled series capacitor (TCSC). A comparison has been made between two different synchronization schemes: synchronization with respect to zeros of TCSC capacitor voltage and synchronization with respect to zeros of line current. No such comprehensive investigation has been reported in the literature yet. A laboratory-scale TCSC has been designed, produced and installed in a laboratory power system at Kyoto University. Effects of the two synchronization systems on the performances of TCSC have been investigated on the experimental system. Steady-state impedance characteristics, dynamic response, and instability of TCSC in a variety of operating conditions have been compared. Both advantages and disadvantages of the two synchronization systems have been clarified.
