Abstract (en)

[origin: DE19642596A1] The invention concerns a method and device for compensating reactive current portions in a non-ideal consumer (12) supplied by a power mains (14), by means of a compensation system (2) which is electrically connected in parallel with the consumer (12) and comprises a pulse current rectifier (4) having at least a capacitive storage device (6). According to the invention, a transmission ratio space vector (ü) is calculated as a function of a determined mains voltage space vector (uN), a mains current space vector (iN), a compensator current space vector (iK) and an intermediate circuit voltage (2Ed) at the capacitive storage device (6), such that, on the mains side, the pulse current rectifier (4) generates a compensator voltage space vector (uK) as a function of the intermediate circuit voltage (2Ed). In this way, a compensator current space vector (iK) which keeps the undesired reactive current portions away from the power mains (14) is set via a coupling filter (8) taking the form of compensator inductance (LK).
