| 摘 要： | 从谐波电流检测原理、交流采样方法和硬件实现方案等方面,研究了基于DSP的UPF谐波电流检测系统的误差,分析了各项主要误差的产生原因及量级大小,并提出了相应的减小或修正误差的改进方法,以提高谐波电流的检测精度.这些方法已在基于DSP的并联型有源电力滤波器实验装置上得以应用.结论亦可为它类有源电力滤波器的设计提供参考.

| Abstract: | Errors in UPF harmonic current detection system based on DSP are discussed from several aspects such as harmonic current detecting principle,AC sampling,and hardware realization.The cause and the quantity of each primary error are analyzed,and the corresponding modified methods to reduce or revise errors are presented.The proposed modified methods improve the accuracy of harmonic current detection,and have been applied to a shunt active power filter experimental prototype based on DSP.The conclusions elicited also can provide some references for designing other types of active power filters. |

| Keywords: | active power filter unity power factor RMS DSP detecting errors |
