A TCR is a thyristor controlled inductor, connected in shunt with the line, in which the thyristor valve is controlled by partial conduction, in order to continuously vary the effective reactance of the line. TCR is a Variable impedance type static VAR generator, in which the reactor current can be varied by applying the firing […]

A Static VAR Compensator (SVC) is a shunt connected static VAR generator or absorber in which control of certain power system parameters are achieved by exchanging the capacitive or inductive current which is possible by adjusting its output. SVC is a common name for a thyristor-controlled or thyristor-switched reactor, and/or thyristor-switched capacitor or combination. Figure
