An Investigation on the Unnecessary of Harmonic and Reactive Current Detection for Active Power Filters(Part II)——Simulation and Experiment

Journal: TRANSACTIONS OF CHINA ELECTROTECHNICAL SOCIETY

Keyword:  有源电力滤波器谐波及无功检测电流控制;
Abstract: 在经理论分析得出经典有源电力滤波器(APF)中的谐波及无功电流检测不是必需的结论的基础上,推出经典APF电流控制策略与电源电流直接控制策略之间的等效关系.在经典控制方案基础上,省掉了负载和APF电流检测单元以及谐波及无功电流或基波有功电流运算单元,保留了经典APF中的电容电压控制器和电流控制器,提供了一个廉价而高性能的APF控制方案.最后对基于上述两种控制策略的APF进行了仿真研究,并用电源电流直接控制方案开发了一台单相APF实验样机.仿真和实验结果验证了理论分析的正确性.
