Abstract
A control strategy based on multiple proportional resonant is proposed to solve the problem of fundamental waveform extraction and harmonic compensation of dynamic voltage restorer in the process of single phase voltage compensation. On the basis of the mathematical model of dynamic voltage restorer, the discretization effect of impulse invariance and bilinear transformation on proportional resonant controller is analyzed to improve the computation performance of digital control. The compensation strategy of an improve fundamental waveform extraction method and multiple proportion resonance on specified voltage harmonic is discussed while ensuring the compensation characteristics of system dynamic voltage, and the influence of controller parameters on system performance is analyzed. The experimental verification is carried out on a 10 kW experimental platform and the results show that the proposed method is easily realized with good fundamental waveform extraction effect and harmonic restriction ability.
