摘要
In the case of a method for feeding reactive power into an AC grid system, in the case of which method at least one line (10) of the grid system has a compensation voltage (Ucomp) produced for it, which compensation voltage (Ucomp) is phase-shifted with respect to the current in the line (10) and is injected into the line (10), simplified compensation is achieved in that the compensation voltage (Ucomp) is produced from a DC voltage by means of an inverter (11) , which is formed by gate turn-off power semiconductors in a bridge circuit, and in that the compensation voltage (Ucomp) is injected in series directly into the line (10) .
