| 摘 要： | 提出了用于一种高压混合有源电力滤波器的改进控制方法,在保证系统稳定性的前提下可显著改善谐波补偿效果,对于负载的≥3的整数或分数次谐波电流,其衰减倍数都>20dB,还可阻尼滤波器支路和系统阻抗间可能的谐振。仿真和实验表明该法滤波效果好,实现简单,控制灵活,较适于高压交流系统谐波治理。

| Abstract: | A modified control algorithm is presented for the hybrid active power filter (APF) applied to high voltage grid. While ensuring the stability of control system, the new algorithm improves filtering effect obviously. By the proposed control strategy, the harmonics higher than 3rd on load can be attenuated to more than 20 dB. It can also damp the possible resonance between the grid impedance and filter. The control algorithm is characterized by well filtering performance, easy realization and flexible control. The theoretical analysis is verified by simulation and experiment to show the possibility of the proposed algorithm applying to high voltage grid. |
