摘　　要：根据广义谐波理论,证明了应用自适应噪声对消技术可实时检测出需要补偿的广义谐波电流分量。该法比传统的谐波检测电路简单、易实现、抗扰性强。以该分量为输出日标电流的单相有源电力滤波器能将非线性负载补偿成纯电阻负载。仿真结果证明了该方法的有效性。Based on broad-sense harmonic theory,the current harmonic can be got in real time through applying adaptive noise canceling technology.The single phase APF can turn non-linear load to be pure resistance by compensating the broad-sense harmonic detected,i.e.,when the system voltage is sinusoidal,the APF can compensate fundamental frequency reactive power and current harmonic in traditional conception simultaneously.The method presented is simple on harmonic detecting circuit and can be easily realized.Theoretical analysis is verified by simulation results.
