ABSTRACT:
An electric power flow controller for controlling an electric power flow of a power system includes a semiconductor switch for controlling a series reactance of the power system. The electric power flow controller includes a first winding having at least one Y-connection, a second winding mating with the first winding, an electric power flow compensator connected in series to the Y-connection of the first winding and for compensating a transmission state of the electric power system. The electric power flow compensator provides a compensating capacitor inserted onto an electric power line. The compensation of the capacitor is controlled by the semiconductor switch. The semiconductor switch keeps an application of a voltage that is equal to or lower than a voltage to ground of the electric power line.
