The article presents a model of a semiconductor compensator with an additional fuzzy control loop for the level of higher harmonics of the supply network current. The model was created and tested in the MATLAB 7.0.1 package. The dependences of the level of switching overvoltages, as well as the level of the amplitude of a single harmonic of the current of the supply network, on the relative voltage across the storage capacitor are investigated. The possibility of effective control of the amplitude level of a separate harmonic of the supply network current is shown. Graphical dependencies were obtained by means of modeling, their analysis was carried out, which confirmed the theoretical conclusions that must be taken into account when setting the parameters of a fuzzy controller. The use of an additional control loop for the level of a single harmonic makes it possible to adapt the proposed digital control system to varying conditions of the power system. The ability to adapt the pro-proponated digital control system in the energy system’s minus has been brought to the table, and the additional contour to regulate the level of the taken harmonic system has been added.
