Abstract

In order to provide an apparatus (1) for flexible power transmission and for deicing of a high-voltage line, which has a plurality of phases, by means of direct current, with an AC voltage connection of the high-voltage line which has a number of phases corresponding to the phases of the high-voltage line, each phase having at least one inductance (6) and a valve circuit (10) connected in series with each inductance (6), with the valve circuit (10) being connected by means of a junction point (11) to the AC voltage connection, and having a first current path (14) with a first power semiconductor valve (12) and a second current path (15) with a second power semiconductor valve (13), with the power semiconductor valves (12, 13) being connected in opposite senses with respect to one another with reference to the junction point (11) and in which case the first and the second current path (15) can be connected to a TCR star point by means of at least one star point switch (16, 17), whose design is simple and at the same time costs little, it is proposed that the TCR star point (18) is connected via a connecting line to a star point of a zero phase-sequence system suppression means (2, 2…
