| 摘 要： | 针对现有DFT（Discrete Fourier Transform,DFT）在非同步采样时存在的问题,提出了一种基于自适应同步抽样算法的滑窗迭代DFT谐波检测算法,该算法通过自动调整采样时间,可大大减小DFT在非同步采样时带来的计算误差。仿真结果表明该算法能实时有效地检测出负载电流中的谐波分量,并生成谐波参考指令电流作用于电力有源滤波器APF（Active Power Filter）,仿真同时也表明该算法具有很好的实时性、目标跟随性和抗干扰性。

| Abstract: | For solving the problems of DFT(Discrete Fourier Transform,DFT)in the non-synchronized sampling,this paper presents a sliding window iterative DFT algorithm based on adaptive sampling algorithm.The algorithm can reduce errors caused by the non-synchronous sampling by adjusting automatically the sampling time.The simulation results show that the algorithm can effectively detect the real-time harmonic current and generate harmonic reference instruction current of Active Power Filter.Simulation also shows the ... |
