  • Abstract

    The active power filter designed to compensate inactive power components. Aim: The aim of the study is to assess the quality of the three-phase active power filter in the distortion of the mains voltage supply, which is caused by the influence of non-linear loads, and then comparing the two active filtering algorithms – the Fryze power theory and p-q theory of instant power. Materials and Methods: Reviewed a three-phase active power filter connected in parallel to the mains via inductance. To study the modes of filter with non-linear loads with non-sinusoidal voltage programmed in Matlab/Simulink the model of electricity system is implemented. As the algorithm of implementation for determining of inactive components of power the Fryze theory and p-q theory were considered. Results: Obtained a time diagrams of network current after compensation when applying the theory of Fryze and p-q theory. Built the graphs of efficiency of reactive power compensation, fall of coefficient of network current distortion and errors of active power under the changing of firing angle of thyristor converter.
