- Abstract
In order to study the harmonic compensation performance of dynamic voltage restorer (DVR) , this paper analyzed theoretically the frequency - domain characteristics of the traditional proportional resonant (PR) controller and the improved one with the function of harmonic compensation, deduced the relevant transfer functions by installing the above two controllers in the control circuit of DVR, compared the dynamic response index and the steady compensation precision, and evaluated the harmonic compensation performance of two controllers. Through the simulation via MATLAB/SIMULINK, and waveforms and frequency spectrums before and after compensation under the two control strategies, which verify the rationality of the theoretical analysis was verified.
