Abstract

This paper presents a new method for the continuous regulation of series compensation. The two proposed control circuits consist of capacitor banks inserted in a transmission line and are controlled by bi-directional GTO switches. The level of compensation is controlled by varying the on and off time of the GTO switch. To avoid current surge, the switch is turned on before the capacitor voltage is zero. The feasibility of this method was verified by transient analysis and through measurements on a small scale model. The advantage of the proposed circuit is the fast and continuous regulation of series compensation. The circuit can be built with available components and can be used, for example, for impedance control, and oscillation reduction.
