| 摘 要： | 采用传统检测电网谐波电流的控制方式时，串联混合有源电力滤波器的谐波补偿性能与系统稳定性之间存在矛盾。文中在传统控制方式基础上增加了一个比例微分环节，能同时提高系统稳定性和谐波补偿性能，并更好地阻尼电网阻抗和并联无源滤波器之间可能产生的谐振。仿真和实验结果证明了所提出的方法的正确性。

| Abstract: | When using traditional harmonic current detection control strategy, a conflict occurs between the harmonics compensation performance and the system stability of a series hybrid active power filter (SHAPF). This paper presents a novel control strategy by adding a proportional plus derivative control unit to the traditional control. The system stability and the harmonics compensation performance are improved at the same time. Furthermore, the possible resonance between the grid internal impedance and the paralleled passive power filters is damped out. Simulation and experimental results validate the proposed method. |
