Abstract

The invention relates to a method and device for improving the current quality of a superimposed network (14) by means of a compensation device (2) which is connected parallel to the network (14) and to a load (12) and provided with a pulse current converter (4). The control and regulating system (10) of the converter determines a transmittance space vector (ü) on the basis of a supply voltage and line current space vector (uN,iN) together with the actual value of a direct current voltage(Vdc). According to the invention, a compensated voltage fundamental space vector (uk,1) comprising a space vector for a compensated voltage fundamental positive phase sequence system and a space vector for a compensated voltage fundamental negative phase sequence system is generated. This enables the compensation device (2) to balance a high dynamic load and to compensate reactive power in relation to the fundamental frequency currents of a particular load (12), so that said load (12) when seen from the point of view of the superimposed network in relation to the fundamental mode can appear as a three-phase, symmetrical, ohmic resistance.
