The Effect of Voltage and Current Harmonic Distortion on Power Indicators in Power Circuits a Dynamic Voltage Restorer

On the basis of the developed model of the dynamic voltage restorer, a subsystem for measuring power indicators was built to assess its distribution in circuit elements. Experiments were conducted to determine the effect of harmonic distortion of voltage and current on integral power indicators in the power circuits of the dynamic voltage restorer. It is noted that there is distortion power in the converter circuits and on the filter elements, which for the inductance is comparable to the full power. Significant reactive power is distributed between the filter elements and the output lines of the converter. In this case, the reactive power of the capacitor is balanced by the reactive power of the inductor and the converter. The storage capacitor in the investigated mode gives active power to the external circuits.
