摘要

有源电力滤波器（active power filter

APF）直流侧电压控制是其关键技术。直流侧电压大小直接影响APF的功率损耗和补偿性能。在某些复杂的工业应用场合

各种负载的波动会造成APF公共耦合处网侧电压的严重波动

影响了其补偿性能。以三线三相APF为例

分析其损耗、补偿性能与直流侧电压关系

提出一种下垂系数模糊自适应的APF直流侧电压控制策略。结果表明:当网侧电压升高或降低时

可以通过提高或降低直流侧电压来提高其补偿性能与降低其功率损耗;仿真与实验验证了其可行性与正确性。

Abstract

Active power filter（APF）DC voltage control is the key technology. The DC link voltage directly affects power losses and the compensative ability of APF. In some complex industrial environment

the fluctuant load brings about the grid voltages fluctuation at the point of common coupling（PCC）

which effects on the compensative ability of APF. The paper analyses the losses and the compensation performance

and introduces an APF DC voltage control strategy based on adaptive fuzzy droop control. When the network side voltage increases or decreases

the DC voltage accordingly increases or decreses. It can improve its compensation performance and reduce its power losses. Simulation and experiment verifies its feasibility and accuracy.
