直流电压稳定是有源调谐型混合滤波器(ATHPF)正常工作的前提和基础。针对有源调谐型混合滤波装置中的有源滤波器,分析了ATHPF中有源电力滤波器(APF)直流电压控制机理,提出了一种基于电网电压定向的直流电压控制方法。建立了有源调谐混合滤波系统的直流电压控制模型,分析了系统稳定性,并对控制器调节参数进行了优化设计,最后通过仿真与实验结果验证了所提直流电压控制策略及系统参数选择的有效性。

The direct voltage voltage stability is the premise and foundation for normal operation of active tuned hy- brid power filter（ATHPF）.Aiming at the active filter of ATHPF device, the control mechanism of active power filter （APF） direct voltage in ATHPF is analyzed and then the direct voltage voltage control with source voltage oriented is proposed.Meanwhile, the control model of the direct voltage voltage control of hybrid power filter system is established. Furthermore, the system stability is analyzed and the control adjustment parameters are optimally designed.Finally,the effectiveness of the proposed control principle and parameter selection is verified by simulation and experiments.
