Abstract (en)

[origin: DE19738125A1] The invention refers to a method and device for offsetting network voltage (14) distortions (uN,v+/-), involving a pulsating current rectifier (4) and an active filter (2) comprising a coupling device for LC oscillatory circuits. According to the invention, at least one complex amplitude (<u>u</u>N,v+/-) and at least one distortion of the network voltage (uN,v+/-), from which a space vector for the partial transfer ratio (üv+/-) and a space vector for the partial transfer ratio (üh) are determined depending on the real value of the transfer circuit voltage (Vdc) in the pulsating current rectifier (4), while control signals (S1....., S6) intended for the pulsating current rectifier are generated on the basis of a space vector for the partial transfer ratio (ü), obtained from the space vectors for the partial transfer ratio (ü v+/-, üh). As a result, the active filter (2) operated, in on connecting point (20) on the network (14), as a complex low impedance resistor for higher harmonics to be mitigated (uN,v+/-), and the capacitive accumulator (6) in the pulsating current rectifier (4) is adjusted according to a set a nominal value for the transfer circuit voltage (Vdcsoll).
