| 摘 要： | 为消除电网中的谐波对电网质量的影响,将单周期控制技术应用于带Z源的高频环节AC/AC变换器,建立了基于该变换器的电网补偿系统.通过AC/AC变换器,产生与电网相位相反的三倍频正弦波,以抑制电网中的三次谐波.最后利用Simulink工具进行了仿真验证.仿真结果表明,电网总谐波畸变度（THD）由7.21%降到补偿后的0.54%,实现了电网的谐波补偿.

| Abstract: | In this paper,for eliminating the influence of harmonics on power supply quality in the power grid,the one-cycle control technique is employed in a high frequency link AC/AC converter with Z-source,based on which,a power grid compensation system is established,where the sine wave that is of three-time fundamental frequency and opposite phase to the grid’s is generated through the AC/AC converter for suppressing the triple-harmonic.By simulation of Simulink tools,it is shown that the grid’s THD drops from 7.21% to 0.54% after the compensation and this studied system can implement the harmonic compensation in the power grid. |
