摘　　要：现有的多种有源电力滤波器(Active Power Filter,APF)单相电路谐波电流检测方法,它们的有效性均采用仿真验证,而缺少实验环节。针对此问题,将UA206 A/D数据采集卡通过PCI口与计算机相连,以电源电压和负载电流作为输入信号可以构成一种简单实用的APF谐波电流检测实验系统。该系统具有结构简单、稳定性好、可靠性高、程序设计较为容易等特点。使用此系统对一种基于神经网络的谐波电流检测方法进行了实验,实验证实使用此实验系统可以方便验证所提出的APF谐波电流检测方法的正确性和检测性能。At present,the validities of many detecting methods for harmonic current of single-phase active power filter（APF） are verified by simulation but without experiments.To solve this problem,a simple practical experimental detecting system for harmonic current of APF is obtained by UA206 A/D data collecting block being joined with computer by PCI port and supply power voltage and load current being regarded as input signals.The system has the characteristics of simple configuration,nice stability,high reliability and easy programmer.Using this system,the experiment of a detecting method for harmonic current based on neural networks is done,and it validates that adopting the system can expediently verify the correctness and detecting performance of the proposed detecting method for harmonic current of APF.
