| 摘 要： | 从改变有源电力滤波器(APF)中输出低通滤波器(LPF)滤波电感的结构出发,提出一种新型并联混合有源电力滤波器(SHAPF)拓扑.SHAPF能减小控制器带宽、增加系统的稳定裕度,有效抑制数字控制固有延迟引起的负荷与系统间阻抗谐振.它能与无源滤波器并联运行,降低有源部分容量,从而减小损耗和降低装置成本,为非线性负荷电能质量治理提供了新的解决方案.这种新的拓扑结构既适用于单相系统,又适用于三相系统.主要对单相系统进行了分析,动态模拟实验证实了该拓扑结构的可行性.

| Abstract: | A novel topology for Shunt Hybrid Active Power Filter(SHAPF) is proposed through modifying the config-uration of low pass filter inductor in the link of APF and utility grid.This new topology effectively reduces the bandwidth of the controller,and thus increase the stability margin of the system.It is relatively immune to load source impedance reso-nance caused by inherent digital control delay.And it can be implemented in combination with passive filters to effectively reduce the power rating of the active part,and thereby to reduce the dissipation and cost.This topology provides a novel so-lution for power quality problems for nonlinear loads.This topology is suitable for both single-phase and three-phase sys-tem,but the paper concernes only single-phase APF.The effectiveness of the proposed topology is verified by ex-periments. |
