Simulation of an Adaptive Detecting Circuit for Harmonic Current

通过基于自适应噪声抵消技术的一种谐波电流检测方法研究,利用MATLAB仿真软件建立相应的仿真电路,并研究电网电压畸变、参考输入电压幅值对检测效果的影响,结果表明自适应谐波电流检测电路的检测效果不受电网电压畸变的影响,但受参考输入电压幅值大小的影响。

The paper introduces a method for the harmonic current detection on the basis of adaptive noise can-celing technology,and uses the MATLAB software to model the harmonic current detection circuit.The influence of grid's voltage aberration and reference input voltage amplitude on the effect of harmonic current detection is studied.The result shows that the effect of harmonic current detection is not influenced by grid's voltage aberration and is influenced by reference input voltage amplitude.
