摘　　要：针对实现负载谐波电流抑制和无功功率补偿的目标,分析了无功谐波电流检测的方法,并在此基础上提出基于平均功率的研究方法,设计了电路原理图;给出平均功率谐波检测算法,并借助M atlab对给出的检测电路进行仿真研究。结果表明了该检测方法的正确性和可行性。Aiming at the controlling object about realizing load harmonic current suppression and reactive current compensation,the method of reactive harmonic current detection were analyzed. A new research method on the basis of average power was carried out. The circuit scheme was designed, and new detection method was given. The detection circuit was simulated by Matlab. The result shows that the method is correct and reliable.
