Abstract

We analyze electromagnetic processes in a three-phase asymmetric network with a parallel active filter and propose a method to calculate its parameters. At the basis of our consideration lies the transformation of the asymmetric representation of the load currents from a spatial representation, a planar one, in which the description of electromagnetic processes by the methods of circuits theory is possible. As a result of the analysis, analytical relations between variables of state and parameters of the filter have been obtained. Basic dependences have been found by which a method for calculating the parameters of the active filter has been proposed. An asymmetric three-phase network with an active filter calculated by this method is implemented within the Simulink-Sim Power System software package. The simulation results confirmed the validity of theoretical analysis and the ability of an active filter to compensate for all the inactive components of power in an asymmetric three-phase network.
