基于DSP的混合有源电力滤波器研究与设计

The Design of Hardware Circuit of Hybrid Active Power Filter Systems Based on DSP

笔者结合我国电力系统谐波污染的实情,设计出了基于 DSP 的并联型混合有源电力滤波器,这种电力滤波器弥补了单一并联有源电力滤波器的缺陷,能以较小的补偿容量对大容量电力系统进行谐波抑制和无功功率补偿。实验结果表明:在局部电力系统中使用该装置后,基本上可消除局部电力系统的谐波污染,可使电能质量大为提高,并且能抑制由 LC 无源电力滤波器阻抗和电力系统阻抗引起的谐振。

In this article, I have designed a parallel hybrid active power filter considering the fact of harmonic pollution in electric power systems of our country. The power filter can remedy a defect of single parallel active power filter, moreover, can accomplish restricting harmonic pollution and compensating passive power for large electric power system. The experimental result shows that this filter can eliminate the resonance resulting from the impedance of LC passive power filter and electric power system and the harmonic pollution after using the filter device in the partial electric power system, and improve the quality of electric energy.
